Diverging from Boring Presentations

Thursday, November 09, 2017 0
Ask your colleagues to create a short presentation on any topic. As a result 90% of them will look absolutely alike. There is a big problem with making the audience engaged in any topic as most of templates were used by other companies and not even once. Such presentations seem boring and not new. There are certain ways on improving the look of company’s performances and lectures. Some of them cost a fortune, the others are pretty cheap.

Designer Templates

When looking for something new, managers tend to check only those websites that belong to official sources. However, young designers have their own hosts for storing artworks. Thousands of high quality templates are offered by https://poweredtemplate.com/ at the lowest price. Some other sites offer their thumbnails for free. But you should mind that images of exclusive design should be paid for.

Presentation template storages usually have other useful thumbnails to offer, like:
  • Diagrams;
  • Charts;
  • Google slides themes;
  • Word thumbnails;
  • Print Templates.

Hire a Designer

If you hate the idea anyone could use a thumbnail before you buy it - hire your own professional designer. That is a nice opportunity to stand out at any event. An employee would create any image according to company’s brief or provide unique pictures that display his or her own view on given topic.

Having a designer in team means working out some unique style for all products of inner and outer use. If your work aims winning more customers - make all your products look elite by giving them a sense of uniqueness with some impressive design.

Most of companies do not hire designers to keep them at the office as specialists as they usually ask for very high salaries. They prefer working with freelancers and talented students. Such cooperation has many benefits:
  • company pays for closed project (for result);
  • freelancers work 24\7;
  • company gets complete control over project;
  • freelancers are more experienced;
  • there always is an opportunity to check designer’s reputation before signing a contract.
Ask Google

Most of people do not realize the true power of modern Internet search system. When sparing some time and effort we are more likely to discover some new approaches for our presentations.

Big enterprises often share their most successful work samples on the Internet. Of course, copying anyone’s work is a crime and that might end up at the court. But how about a thorough research? Find a few presentations that would impress you and your team and create something even better than that adjusting regular thumbnails from image banks and other free websites for your slides.

Some companies often take some professional images of their team and office to add them as background. There is nothing wrong with using some experience of manufacture giants. Such system helped many companies find their own style.

Increasing Cyber Crime and how to avoid becoming a victim of it? (Heimdal PRO Review)

Wednesday, November 08, 2017 0
It seems like almost every week there is a new type of malware or ransomware making headlines, threatening our online security and bringing an organization to its knees. The stolen funds, hard drive encryption, theft of confidential corporate information and bad publicity are front page news. Cyber criminals are becoming smarter and using innovative techniques to get into someone's computer and access valuable data. 

Given the evolution of information technology, almost every organization is adopting or migrating to emerging technologies, such as cloud, social and mobile computing, to interconnect their different offices for exchanging information and conducting business online. This has not only increased their online presence but also their exposure to security threats and cyber crime. Cyber criminals are not only targeting businesses but individuals too. Nowadays everyone is connected to the internet almost all the time either through wireless or mobile data and thus no one is immune to cyber threats. And after so many cyber criminal incidents, I must say that antivirus alone is not enough to protect your PC from such malicious viruses, malware or ransomware. So the big question is "How can you protect yourself or your organization from cyber threats?"

As attackers employ advanced innovative techniques and exploit security vulnerabilities, you must keep yourself up to date with the latest developments and research on cyber threats to avoid becoming a victim of cyber crime. If you are running a small business or working as an IT professional for an organization, you must also adopt strict cyber security measures in order to respond to these increased threats and protect your business or company from any types of cyber threats such as hacking, virus attacks, spyware, malware, or ransomware attacks, etc. Here are some cyber security basics that everyone should be aware of.

How do you protect yourself from cyber threats and avoid becoming a victim of cyber crime?

#1. Keep your software up to date

First thing’s first, make sure you keep all your third party software and operating systems up to date. Obsolete and outdated software is more vulnerable to cyber attacks as it has many loopholes and flaws. Keeping them all as up to date as possible at all times closes the vulnerabilities and mitigate exploits which alone stops more than 85% of cyber attacks targeted towards vulnerable software.

#2. Use a good Antivirus program and keep it up to date

Antivirus, if updated regularly, can protect your computer from being hacked or infected with viruses, Malware, Ransomware, as it always scans files transferred or downloaded to your computer from external sources.

#3. Use a Good firewall and Internet Security Suite

Firewall actively monitors your network traffic as it filters every incoming and outgoing data packet in order to prevent unauthorized apps or internet users from accessing your private network while it is connected to the internet. So basically, it acts as a barrier to keep foreign elements out of your computer and your private network. Though the firewall can filter data packets, it’s not very effective in recognizing malicious worms, malware and most viruses, so it can't make you 100% safe online. Due to the advanced sophisticated technologies used by attackers, firewall has become obsolete now and a more powerful and proactive preventive solution is required, as almost every week there is a new type of malware or ransomware detected. So the new  solution, known as Internet Security Suite, is being used to detect most viruses, poorly configured Wi-Fi networks, spam emails, silent installations of spyware and malware, which a normal firewall or antivirus can’t detect.

Now the question is "how many of such software solutions do you need?" and "are they effective enough to provide you with full security and keep you completely safe online?" and, most importantly, "are they proactive enough to fight against the current evolving and emerging security threats?" 

After reviewing multiple antiviruses and internet security suites, I stumbled upon one of the best security software named Heimdal which is unique in its type as it does not only block incoming attacks, ransomware, banking trojans, phishing attempts, but also updates or patches third party applications in order to close vulnerabilities and mitigate exploits. Most importantly, its professional version, Heimdal PRO, doesn't rely on analyzing the malware's code or its behavior like antiviruses do. It uses advanced traffic monitoring and filtering technologies to protect your PC from any types of malicious content and security threats. Before we move further, let me explain how Heimdal is different from other internet security products. Also just to check its effectiveness we also installed it on our system and ran several security checks and it passed them all, so we rate it 5 out of 5. Read this review to understand how effective an internet security software should be.

What is Heimdal ?

Heimdal is a security product designed to run as supplementary protection or to create an additional layer of security to antivirus on Windows PCs. It is designed by highly skilled cyber security experts from a Denmark-based company known as Heimdal Security. Their security product and resources, such as free courses on cyber security and cyber security alert section on their blog, have been featured in top news and media outlets from all over the world, among them being Forbes, PC Mag, The Guardian, Business Insider, Info Security, The Inquirer, and many more.

Also remember that Heimdal doesn’t replace your existing Antivirus or firewall, but is rather designed to enhance and compliment these security product. As we already discussed,  antivirus alone is not enough to give you 100% protection from viruses, malware or other such malicious content. It is a lightweight security product, which doesn't utilize much memory and resources on your PC, and makes your security arrangement 100% complete after it is installed along with a traditional antivirus program.

Why Heimdal?

As hackers or cyber criminals are becoming smarter and using advanced techniques to penetrate private networks, antivirus alone is not capable of protecting against such attacks, so you need a solution which works alongside your antivirus and add an extra layer of security to your computer. Heimdal is that type of security software which is easy to install, lightweight and does not hog your computer’s memory and processing power. It updates and patches all your vulnerable third-party software, silently, without any effort on your side.

It's important to note that it's not an antivirus, but a product with a different approach to internet security. The key difference between Heimdal and antivirus is that Heimdal focuses on the advanced Traffic Scanning and Filtering to fight against incoming attacks, 2nd generation malware, ransomware, rootkits, phishing, financial Malware, banking Trojans, botnet inclusions, drive-by attacks, data leakage, etc. It scans all your HTTP, HTTPS and DNS traffic, not just the URL typed in the browser's address bar like other antiviruses or internet security suites do.

How to install Heimdal and how effective is it?

The installation and setup of Heimdal PRO is very simple. You just need to download the installer from the official website. Click here to download Heimdal PRO free for 30 days. The installer named Heimdal.DeliveryLauncher.msi is just 756 KB in size.

So if you are looking for an effective and powerful internet security software, I recommend giving Heimdal PRO a try, as it is lightweight and available at a very reasonable price with so many rare features.

Now let’s get back to the basics of cyber security and the practices we should follow to prevent our PC and data from cyber attacks. Apart from the above mentioned major steps and the software installation, you should also do the following.

#4. Use unique and strong passwords for each website, change your default password as soon as possible
#5. Enable two-factor authentication wherever available
#6. Avoid connecting USB flash drives or hard drives you don't trust to your computer.
#7. Carefully read the message and permissions while installing a new app and don't just keep clicking on the next button.
#8. Don't send or upload sensitive personal data via email or cloud sharing, if necessary, do encrypt it in a zip file before sending or uploading it.
#9. Make sure the website is secure by looking at the padlock sign in the address bar before entering your personal or financial information.
#10. Avoid using or logging into your main accounts on public computers or while connected to a free shared Wi-Fi network.
#11. Regularly back up your important files to avoid losing them
#12. Review your social media security settings and security questions. Change them immediately if you suspect someone knows them.
#13. Most importantly, keep yourself always updated with the latest trends, development and research in the field of cyber security, as it gives you important information on how to avoid being a victim of new emerging threats and what precaution you should take. Almost all major software manufacturers keep updating their blog with such incidents, causes and remedies. Heimdal 's security alerts section on their blog is one of such places where you can find the latest information on hot researched topics and breaking news about new threats and their evolution. You can also subscribe to their blog to be the first to know and stop cyber attacks.

Tez- A new Payments app - Why Google is Pouring Cash into its promotion?

Sunday, October 29, 2017 0

Learn what is Tez and how is it different from other e-wallets and payment apps!!

On Sep 18, 2017, Google launched its new Payment and money transfer App-Tez, specifically made for India. Tez, is an Urdu word which means fast, and no doubt the Google's Tez app is very fast in transferring or sending money within the country. As Google launched this App exclusively for Indians, so it also supports other regional languages like Hindi Bengali, Gujarati, Kannada, Marathi, Tamil, and Telugu in addition to English. The App has become increasingly popular these days and people are doing as much transaction as possible in the hope of getting rewarded with cashback from Google. Google is running various cashback and lucky draw offers for its Tez users to encourage them to do more transactions and attract more users.

With the launch of Tez app, Google joins India's crowded mobile payment market and is set to shake up the fintech segment which is currently ruled by Softbank-backed Paytm and by the likes of BHIM. Google's entry into the digital mobile payments is definitely going to benefit the users and help democratize digital payments segments.
Tez - A new Payment app by Google
Tez - A new Payment app by Google
As reported in different newspaper articles, the app was downloaded by five million Android users just within the 24 hours of ‘Tez’ being launched. Google Tez is also luring the Android and iOS  users by offering a total of ₹9000/- per year as reward. And the best thing about the reward is that it comes in the form of cash, directly into your bank account and there is no discount code or promo code that you need to remember as its applied automatically and you get rewarded in most of the transactions. With this new promotional approach and a huge Android users base, I am sure Google is going to make most of it.

What is Google Tez?

Unlike other e-wallets such as Paytm, MobiKwik, or Freecharge, Tez is neither a mobile wallet nor a Payments Bank or a modified version of Android Pay. It seems like a mixed modified version of PayPal and Android Pay. In Tez, user is just required to link his/her bank account to pay for items in physical or online stores and to receive money directly into the bank account. So the money is never loaded to any wallet or such form neither is temporarily held by Tez but money is moved from one bank account to other instantaneously. Tez works on government's backed UPI and BHIM app interface and its just like a platform that connects your bank to UPI and provides you with a UPI address to send and receive money. Gone are those days when we used to share the long bank A/C no., IFSC code, Account holder's name and name of the bank in order to send or receive money and now with the advent of UPI, sending or receiving money has become much easier as it only needs the virtual Payment Address (VPA) or the UPI ID which looks like yourname@yourbankname. For more information on UPI and BHIM app you can read the previous post - What is UPI payment method and BHIM app?

In order to signup with Tez- A user must have an Indian bank account, and a local phone number registered with the same bank account. Google has partnered with Axis, HDFC, ICICI and SBI bank to facilitate the payments processing across over 55 UPI-enabled banks. Tez also introduces a new feature that runs on a Google's proprietary technology called Audio QR (Patent filed by Google) which allows one to send money to a nearby Tez users without sharing any personal and financial information which can be a best option to make payment to a Chaiwaala, Cab driver or a Rikshaw driver.

It is designed in a chat like interface which is easy to use. With this app you don't need to share your personal information or bank details with other party. Now you can pay your taxi fare without sharing your details, just the UPI id is enough. Some big names like Dish TV, Uber, Red Bus, PVR, Domino's and Jet Airways has already included Tez as a payment option and of course, because it uses UPI, you can pay almost any merchant who supports payment through UPI.

Google is also planning to partner with companies like Micromax, Nokia, Lava, Xolo and Panasonic for pre-installing the Google Tez app on all upcoming smartphones from these brands.

How does Google Tez work?

Tez works on UPI based payment method. User has to link his/her bank account after signing up and then set a UPI pin for carrying out the secure transaction. Using Tez, you can send money to any Tez user's phone number, any UPI ID and any bank account using Account number and IFSC code. Money is instantly debited from your linked bank account and credited into the recipients account number. Another option is by using the camera to scan QR and the App's Cash Mode which is built using Google's proprietary AQR (Audio QR) technology which finds other Tez users in proximity and the money can be transferred without sharing Mobile number, Email ID or Bank account number. Tez is also safe and secured by both Google App PIN and UPI Pin.

How to get started with Tez?

  1. Using Tez app to send or receive money is very simple, Just download the Tez App from Google Play Store or the iOS App Store.
  2. Set your Google Pin or Screenlock for the App security.
  3. Add / Link your bank account and set your UPI pin while adding the account.
  4. Add mobile number registered with your bank account.
  5. And start sending or receiving money with your Tez UPI id which may look like your gmail userid@okicici or userid@okhdfcbank or youruserid@okaxis.
The best part is that you get instant rewards of  ₹51/- as pure cash into your linked bank account when you are referred by someone and you make the first transaction from Google's Tez app (Even a transfer of ₹1/-). You can earn further by referring more friends and and family members when they install Tez from your referral link and they make a minimum transaction of  1/-. If you are new and never heard about it then you can use the below link to download Tez and send money to someone from your contacts or add money to your Paytm wallet using the UPI ID created by Tez and both of us will be rewarded by ₹51/-.

How Google Tez is different from other mobile wallets ?

As I already mentioned in previous paragraph that the Google Tez app is neither an e-wallet nor a Payments Bank or a modified version of Android pay. It's just a platform that connects you Bank account with UPI or BHIM interface and allows the user to send or receive money to and from the linked bank account. Your money remains with the bank and so you do not need to deposit the money to the app wallet or interface, prior to make any transaction. Just choose to pay and verify the UPI Pin to complete any transaction.

There is no charge on any types of transactions done through Tez app while banks and other mobile wallet apps charge a commission on NEFT, IMPS and RTGS transaction and also limit the amount you can send at one time. However, Using Tez you can transfer the maximum amount allowed by UPI methods as set and specified by the government. As of writing the maximum allowed transfer through UPI is ₹1,00,000 ($1,561) on daily transfers and Tez will let you do the same. Most of the bank apps only allow 20 transfers in a day but there is no such limits on Tez.


As already mentioned, its unique AQR technology allows you to pay or send money without sharing any personal or financial information. Simply select cash mode and put the app on send mode and the receiver will put his app on receive mode. Tap on the name from the list of nearby detected Tez users and send money to the selected user. It's that simple like transferring movies or music using SHAREiT. It's designed as a lite app with smaller size and can run even on a slow internet connections.

Benefits of using this TEZ app:

As an introductory and promotional offer Google is rewarding both referral and referee with a cashback of ₹51/- direct into their linked bank account. Apart from that, every transaction of amount 50 or more is rewarded with a scratch card of upto 1000/-. You won't believe that both you and the other party whom you are sending or transferring money to can earn extra cash while sending or receiving money through Tez. I did not believe that either when my friend told me that he was lucky to get rewarded with 3000/- so far by doing multiple transaction using Tez. I downloaded the app and started sending payments to people whom I work with and luckily I got additional 1200 in my bank account from referral and scratch card bonus within 3 days. Here are the screenshots of the rewards.
Tez - Cashback and Rewards
Tez - Cashback and Rewards
So download Tez app and start using it to become Tez as I am sure in near future or withing 2-3 months from now every one will have a Tez ID just like a WhatsApp and Facebook account and thus sending or receiving money will become much easier. You can earn a maximum of 9000/- in a financial year by referring someone and also you can be luckier to get rewarded with 1 Lakh in a week if you make transaction of 500 or more as per Google Tez. All these rewards and cash that you win gets transferred directly to your bank account.

How to Send money using Tez?

  1. Simply select the option new and type the name of the recipient or Tap Account number to send money using Bank A/C and IFSC code. Select UPI ID, QR or Phone option to send money using UPI or Phone number.
  2. Type the UPI ID or Phone number of the recipient, Tez will check if the information is correct and shows you the name of the recipient if its correct.
  3. Type the amount > select continue and then verify the UPI Pin to send money.
  4. Similarly you can also request money from someone by simply clicking on the request button instead of send.

How secure is Tez ?

Well, being an app from Google itself certifies it as the most secure App. Though it has UPI PIN, Google PIN and Tez Shield which create multiple layer of security as told by Google India. Tez Shield protects from possible spam, fraud or hacking. If there is any concern or the transaction fails you can contact Tez support team right from within the app. 
To contact Tez support team tap on your name on top left and select "Help & feedback" under Information section. Select to request a callback or chat with a representative or send a feedback.

Some drawbacks of Google Tez:

Though the app is much faster, reliable and secure but some loose points are there which can make you think to use this app or not. If you are already using other UPI app like PhonePe and Chillr then you may not want to switch to Tez as you can pay your utility bill, insurance payments, store payments using QR code or you can do mobile recharges right within the app easily which you can't in Tez at least for now, for e-payments you still have to use other wallets like Paytm; PhonePe, Mobikwik while Google Tez is simply for basic money transfer.

Unlike other e-wallets such as Paytm, you cannot add or borrow money from credit card or debit card into your wallet.

That was all about the new payment and money transfer app from Google which is really fast and because of UPI featuring app it is easy to send or receive money just by typing the UPI ID or looking through your contacts. I have been using the Tez for almost a month now and really love it. Share your experience using Tez with us if there is something interesting or problematic do let us know here in the comment section.

Some of the best pdf readers for Mac

Monday, October 09, 2017 0
In order to read PDF files on your Mac device, you will need a suitable reader that’s made for Mac. The default view may have limited capabilities and thus the need for a more powerful PDF program. They may handle the most basic of functions but you can’t do more than that. Preview is the built in application of Mac which is generally okay but still limited.

Mac boot process stucks on Grey Screen with apple logo after upgrading to macOS Sierra - [ Fixed ]

Sunday, September 24, 2017 0
Have you ever experienced or heard about Mac which gets stuck on grey screen with Apple logo and a progress bar during boot process or has it ever happened with you that your Mac doesn't boot and stalls on the grey screen at startup just after you upgraded to macOS Sierra or El Capitan. If you are experiencing any of these problems and looking for a solution then trust me this will be the best organized article for you to fix Mac grey screen issue and recover from no boot situation while saving your precious data.
Mac boot process stucks on grey screen with Apple logo
Mac boot process stucks on grey screen with Apple logo and a progress bar
Though, It's a rare problem but I am sure most of the Mac users might have experienced it at least once. There is no doubt that Apple provides its customers with the best piece of hardware for a beautiful user experience but still as we know, nobody is perfect in this world and Mac is just a machine and so can malfunction at times. Problems can be of different types but the problem at startup is most frustrating that makes you lame and cripples you the most especially when you have some important data in your computer. This article focuses on solving Mac grey screen problems or no boot situation after upgrading to macOS Sierra or El Capitan. Different people call it by different names but no matter what you call it, the solution to all the following problems would be the same.
  • Mac boot process stucks on Grey Screen with apple logo or a spinning wheel
  • Mac Stucks on boot screen after Sierra upgrade
  • MacBook Shows grey screen with no logo
  • Grey screen of death
  • Mac stalls on the Grey Screen at Startup
  • Apple logo and a progress bar underneath stuck at approx 3/4 
  • Mac booting to a grey screen with a spinning wheel underneath
  • Stuck on dark grey Apple logo 
  • Mac stuck in a reboot loop
  • White screen with grey Apple logo on it
Some Mac users have also reported that their machines stuck in reboot loop after upgrade and it happens like Mac boots into a grey screen with a loading bar or spinning wheel underneath and stuck there for sometimes and then it either shuts down or turns off the display to save power which sometime gets mistaken as powered off state. Let me tell you the most important information- if you see a dark grey Apple Logo with a loading bar, 90% of the chances are that the hardware are fine as it's an stage where macOS boot loader ( BootX or Boot.efi) tries to load the kernel extensions (or drivers also known as kexts) essential to run major hardware component of a Mac which then passes the control over to system processes to create user environment and show desktop or login window. So, if during the loading process, the Boot Loader encounters any incompatible kernel extension or a kernel extension from unidentified developers it halts the boot process and leaves the Mac stuck at grey screen during startup.

There could be so many possible causes to this grey screen problem, sometimes an incompatible or malfunctioning hardware attached to the Mac or low disk space on your startup disk stalls the Mac during initializing the system processes. In order to solve or understand this problem you must be aware of the booting process of a macOS systemHowever, if you simply need the solution to this Mac grey screen problem then you can jump over to the troubleshooting part described later in this article. This article gives you an in-depth knowledge of Mac booting process and reasons why your " Mac stucks on grey screen during startup and how to solve this startup problem on Mac.

In most of the cases this whole story begins after you upgrade. Upgrading to new software version is obviously an exciting exercise but who knows that it will go a bit pear-shaped. Sometimes you don't even know when and how you upgraded you Mac as it happens automatically in the background when " Install updates automatically" is selected in the App Store preferences.

Understanding Mac Boot Process

Just like Windows and Linux, Mac also has its own boot process which goes through certain phases and each phase / sequence has different screen that appears to indicate the startup progress. From pressing the power button to get into the desktop it goes through four major boot phases /sequences which are as follows.

1). Boot ROM Initialization
As soon as you press the Power button to turn the Mac on, it initializes the small program code called BootROM which controls two other sub programs called POST and EFI. They basically checks and activate all the connected hardware components essential to boot your Mac. As it does the POST, the Display remains black until the BootROM sends a video check signal which turns the screen grey. EFI selects the preferred operating system partition to use and then passes the control over to Boot Loader called Boot.efi.
    2). Executing Boot Loader
    Once the Boot.efi is loaded, it draws the “Apple logo” on the screen. The primary job of this Boot.efi file is to load the essential kernel extensions (hardware drivers also known as kexts) from its cache folder located in /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache directory into main memory(RAM) and then allow the kernel to take over the system. Boot Loader starts loading the kernel extensions, a progress bar or spinning wheel appears underneath the Apple Logo on the screen indicating the progress in boot process.

    3). Kernel Initialization and Rooting
    When all the essential kernel extensions have been loaded by boot loader, it passes the control over to recently loaded kernel extensions and the user still sees the screen with grey Apple logo with a loading bar. This phase is known as Kernel initialization and the loaded kernels start loading additional drivers and the core BSD Unix system necessary to boot a Mac and then later it initializes the I/O Kit which links the loaded drivers into the kernel. At this stage the screen changes to a dark grey spinning gear right below the Apple logo. It finally mounts the System partition which is known as rooting and then passes the control over to the root system processes which show the login screen and create user interface and environment.

    4). System Initialization
    At this stage, the dark grey Apple logo is replaced by the login window or the user’s desktop background if the auto login is enabled. This phase mostly includes initializing and executing system services and creating user environment.

    So that was the shortest way to understand macOS boot process. Read the post "understanding macOS boot process" if you want to learn in depth. Now let's move on to the next topic which discusses about the reasons behind "Mac grey screen" Startup Problem or Mac stalling at Apple Logo with grey screen.

    Reasons behind Grey Screen Startup Problem or Mac stalling at Apple Logo : 

    Macs can stuck at startup due to various reasons and show different screen in every situation. This problem can occur anytime not just after upgrading to macOS Sierra but due to other various reasons as well. If you are seeing a dark grey screen with a loading bar stuck at 75 percent, or a spinning gear just underneath the Apple Logo then it is most likely that your Mac is having trouble loading kexts, drivers, or other system processes. But if you are seeing a spinning globe, a prohibitory sign, a grey screen with a flashing question mark on a folder icon, or just a black or very dark display instead, then it could be a sign of corrupt macOS, startup disk failure or any other hardware issue. This article is mainly focused on the start up problem which shows a dark grey screen with a loading bar or a spinning gear just below Apple Logo.

    After reading lots of discussions forum and supporting hundreds of users, here are the reasons that I have learned which causes the Mac stuck during boot.
    1. The installation did not process correctly.
    2. The third party kexts and drivers are not compatible with the new version of macOS.
    3. Corrupt File System or Permissions Error on startup disk
    4. No internet or insecure Wi-Fi connection during installation
    5. Low Space on Startup Disk.
    So it can be both a software or hardware related problem. Hardware related problems can be easily detected by running disk utility and hardware diagnostic test while software related issue are bit lengthy and can be fixed by following couple of troubleshooting steps. Hardware related issue can be dangerous for your data and you should immediately attempt to back up your valuable data such as Photos, contacts, email, invoices and projects to prevent it from losing. The best way to protect them is by installing macOS on an external drive and transfer data from the internal hard drive to the external one. If you have already been taking time machine backup then you need not to worry as all the data are in the backup disk and you can simply restore from time machine backup and all the issue will be fixed.

    Solution to Grey Screen Startup Problem or Mac stalling at Apple Logo

    In this tutorial we'll cover a wide range of troubleshooting tips to solve Mac grey screen problems after upgrading to macOS Sierra or El Capitan and I am sure that one of the steps mentioned below will fix the stalling or freezing of a Mac at grey screen. Please go through all the troubleshooting steps in the same order as it's written. You can simply skip the rest of the articles after the step that fixes your Mac.

    #1. Shut down, disconnect all the peripherals and restart

    Obviously, the first troubleshooting we always do is restart the Mac and see if the issue is fixed. One of the most common causes of a grey screen issue is a bad peripheral or its cable. A bad peripheral can make its associated driver software stuck in loop while it waits for the peripheral to respond to a command and thus can prevent a Mac from starting up, and cause it to stuck. So shutdown the computer first by holding the power button down for 10 seconds and the Mac will go off. Now disconnect all the peripherals (Printers, USB hub, hard drive, scanner, Camera etc.) except keyboard and mouse and try to restart. If the Mac boots successfully, then it's a problem with one of those peripherals. Plug one peripheral at a time and restart again to isolate the problem. This way you can find the problematic peripherals, which will cause the Mac to stall again at start up right after connecting it. Try without keyboard and mouse as well if the Mac does not boot even after disconnecting all other peripherals.

    Once you have found the problematic peripherals you can look for an update or try to find a solution from its manufacturer's web site and see if others are also reporting the same problem. Or you can simply replace it with a new one instead. If this step does not fix the Mac stalling at grey screen issue then move on to the next step.

    #2. Restart in Safe Mode

    It is always a good practice to start your Mac in safe mode when it doesn't boot in normal mode or have any other problem. Safe Boot in Mac is different than Safe Boot in Windows, as it attempts to fix problems while booting. Safe Boot itself fixes hundreds of problems. So start your Mac in safe Boot mode by holding the Shift key down during boot up and and see if it boots successfully.
    You may also like to read: What is safe mode and how to start your Mac in safe mode.
    Once it is booted safely, make sure
    Safe Boot is always slower but If the boot process still stuck or stall during booting in safe mode, then the problem is likely caused by a third-party kext and drivers, or your startup disk is damaged or malfunctioning. If the problem persist, follow the next step to find the problematic kext or verbose.

    #3. Boot your Mac in Verbose Mode

    Booting in verbose mode is not a problem solving step rather it's a diagnostic process. All it does is list all the extensions and drivers on the screen while they are loading during boot. So it shows the detail what’s going on in the background, similar to watching a Linux machine start up.
    Start your Mac in Verbose Mode if it stucks on Apple logo during boot
    Start your Mac in Verbose Mode if it stucks on Apple logo during boot
    To boot a Mac in verbose mode - Simply turn on or reboot it and immediately hold down ' command + v ' keys at the same time. Note down the name of the kexts, driver, or service which is the last in the list of loaded items or the one boot loader is struggling to load before the Mac goes into stall or stuck mode again. Remove the problematic kext or drivers in recovery mode.

    #4. Make sure that your Wi-Fi connection is secure and has a Unique SSID if trying to upgrade over the Wi-Fi

    If you are experiencing this "grey screen" or "Mac stalling at apple logo during boot "issue just after upgrade or in the process of upgrading to El Capitan or macOS High Sierra then it could also be an issue with internet connectivity. Make sure your internet is working - try opening any webpage on other devices connected to the same network.


    Also please note that - Apple recommends you to have the device connected through a WPA/WPA2 or WPA2-Personal secured Wi-Fi network if you are trying to contact Apple server. Apple server may reject the download request if your device is connected through an unsecured public network or a network with a common default SSID name like linksys, netgear, dlink, wireless, 2wire, xfinitywifi, and default. You can also switch from wireless to a hardwired connection.

    #5. Reset SMC and NVRAM

    Resetting SMC and PRAM fixes hundreds of problems including Apps misbehaving and hardware malfunctioning (keyboard, lights, fans, Battery, Charger) and slow Mac despite low CPU load. SMC manages the power specific settings and customization ranging from screen brightness levels and settings for peripheral attached to Mac to settings in Energy Saver like auto-dimming based on lighting and power sources, sleep when idle, screen sleep behavior, etc.
    Sometimes, after upgrading to El Capitan or macOS Sierra, you may need to reset SMC for the settings to become compatible with the new macOS. Resetting them does not risk the loss of any data or other adverse effect. Resetting SMC and NVRAM are a simple task of holding "CTRL+Shift+Option" keys and "Command+Option + P + R" keys respectively. So just go ahead and fire these action without any worry. Resetting NVRAM is always recommended when you're experiencing issues with startup problem, Mac stalling at grey screen,  startup disk or any kernel process panics. Both of these components are important for your Mac to run it properly, but once they get corrupted, things gets cranky. If your Mac doesn't boot after Sierra upgrade, you should reset SMC and PRAM.
    To reset SMC read the post on "How to Reset SMC?".
    To Reset PRAM read the post on " How to reset PRAM?".

    #6. Startup Disk Selection

    As mentioned earlier resetting NVRAM affect the settings for startup disk so post resetting the NVRAM , you may need to select the correct working startup disk specially if you have more than one operating system or hard disk installed on a Mac.
    So simply start your Mac normally and hold down the "Option" key as the computer starts. You will see an option to select the desired operating system or startup disk from the list. Use the left or right arrow keys to make selection and press the "Return / Enter" key to boot from it.

    #7. Use Disk Utility in Recovery Mode

    Disk utility can turn out to be the most useful tool when a Mac is in no boot situation or it boots to a grey screen and stuck on Apple logo with a loading bar. 50% of the troubleshooting is performed here in disk utility and thus it's a key to resolve such problems. Here are the Major task that we perform when in disk utility in context of grey screen startup problem.
    1). Repair Startup Disk
    2). Repair Disk Permissions.
    3). Check the Free Space on Startup Disk
    4). Perform Disk Management ( Restoring, Partitioning, or Erasing the disk)

    Repairing startup disk and disk permissions

    Turn the Mac on and immediately press and hold "Command+ R" keys together or simply hold down the option key as the computer starts and then select Recovery HD to boot your Mac from recovery partition. If it doesn't boot from Recovery Partition, jump over to the next section.
    Once the Mac has booted from recovery partition, you may be asked to select the language, choose English(US) and click arrow key at the bottom to continue. Now select disk utility from the four macOS utilities options and hit continue again. You will see exactly the same Disk utility as it appears in macOS environment when boots normally. One of the most important checks you should perform here is verify the SMART status of the startup disk. So select the name of the startup disk (that also shows the make of and Capacity of the hard drive) from the left pane and not the volume which appears indented below the drive, then look for "Smart Status" on the bottom right side. If it shows anything other than Verified, then it is most likely the problem with startup disk and you should immediately take the backup of your disk and replace it.

    If the smart status shows verified then select the startup disk from the left and click on "First Aid" tab from the top tools bar and then click on run and continue to perform disk check and repair on startup disk. Disk utility will now verify disk for any error, corruption in file system, permissions error, corrupt directory entries and other problems related to files and directories, etc. If it finds any problem, it will try to repair it and if it can not repair the problem it will suggest to format the disk and reinstall macOS as a fresh, which you won't like to do before taking backup of the disk. At this point, you can either take the backup of the disk using restore option in the disk utility or install macOS Sierra on an external USB hard drive then copy all the data from the original startup disk to the external hard drive and then erase the startup disk and reinstall macOS on the original internal startup disk again. For more detailed information on verifying and repairing your Mac's startup drive using disk utility in recovery mode, read this post.


    Remember that, older Mac OS X v10.10 and below used to have two separate task buttons under First Aid tab, which were repair disk and repair disk permissions but the OS X El Capitan and above has got this eliminated to just one first Aid button which does the both tasks.

    Checking available Space on Startup Disk

    When you turn the Mac on it actually loads the essential programs like drivers, hardware extensions or kexts, user interface such as Finder and various other apps which are temporarily stored in physical memory (also called RAM) and a part of the RAM is virtually allocated on the startup disk to which it swap information between, so your Mac must have enough free space on the startup disk for virtual RAM to swap or exchange the information in order to make computer operational. 

    When we are already in disk utility, why not we check the free disk space on startup disk, also, as this could be another reason to grey screen startup problem. When you select the startup disk on the left pane in disk utility, you would be able to see the available free space on the bottom right hand side. Make sure you have enough space available for macOS to boot and work properly. You should have at least 10GB of free space. If you have enough space then skip and move on to the next step.

    If the available space is less than 5 GB, you must delete some unwanted or duplicate files or stuff that you already have backed up somewhere else, too. If the Mac were able to start in safe mode, it would have been easier to free up disk space on startup disk as you could have simply gone to different folders, checked the unwanted file and deleted them and finally emptied the trash to claim more space. But my assumption at this point is that the Mac couldn't boot even in safe mode and so the only option left to you is use recovery mode. So, follow the steps mentioned below to free up some disk space.

    How to free up disk space in recovery mode when your Mac doesn't boot to safe mode or normal mode.

    1. Simply boot to recovery mode by holding "CMD+R" keys during starts up.
    2. Go to Utilities menu up at the top and select terminal.
    3. Type "ls /Volumes" to list all the mounted volume or partition.
    4. Note down the exact name of your startup disk, in most of the cases it is named as " Macintosh HD"
    5. Now type " cd /Volumes/"Macintosh HD"/Users/" and then type " ls " to list the home folders of all the users on Mac. Double check every command for typo before executing it as it could be dangerous and lead to data lose. Also its a good practice to use ls command every time to list all files and directories of a folder to be sure that you are in the right working directory and it contains the item you want to delete.
    6. In order to free up space on your startup disk, you will need to delete unwanted files/folders. If you have more than one user account and you do not need anything stored by the other account you can simply delete the home folder belonging to the unwanted account. It can free up gigabytes of space. Type the following commands to delete all the contents of that user.

    rm -rf user_name  (replace user_name with the real name of the home folder belonging to unwanted user account)

    7. Delete users logs and caches - Type "cd Library" and hit return and then type "ls" to make sure you have the logs and Caches folder. Type the following command.

    rm -rf Logs/*
    rm -rf Caches/*

    it will take some time to delete all the contents and return the prompt again once the command is executed.

    8. You can also clear the downloads folder if not required as it mostly contains the stuff that you can download again. To clear the downloads folder - come out of the library folder first by typing the following command
    cd ..
    rm -rf Downloads/*
    Similarly, you can delete some files/folders from desktop and documents folder after checking the list using "ls" command.

    9. Similarly you can go to Movies and iTunes folder under library to delete some videos and iTunes backup files to quickly recover gigabytes of space. Refer to the article " Startup disk is almost full issue" to find out their location and other such files to delete.

    10. Now to go to Applications folder and list all the applications you have installed. Delete or remove those you do not need to claim some more space.You may find the installation files of previously downloaded macOS version which is taking more than 5GB of precious disk space.So, type these commands to delete them.
    cd /Volumes/"Macintosh HD"/Applications
    ls
    rm -rf "Install macOS High Sierra Beta.app" (Type the name with quotes)

    When you are in the /Application folder, also look for any Antivirus or security software. If there is any delete them permanently as they are not required at all.

    10. Finally after deleting all the unwanted items you need to come back to the user's home folder and clear trash. To clear trash in recovery mode, type the command written below.
    cd /Volumes/"Macintosh HD"/Users/replace_user_name
    rm -rf .Trash/*

    Here are the sample of those terminal commands that I used in recovery mode. So, once you have deleted the all junks and unwanted files, quit terminal and go to disk utility and verify if the startup disk has enough free disk space. Finally, restart the Mac and check if it boots normally.

    What if your Mac doesn't boot from Recovery Partition either

    If the Mac is not booting from recovery partition either, chances are that it's startup disk is damaged or your Mac did not have a recovery partition. You can further read this post to check if your Mac has a recovery partition. Now the options left to you are
    1). Try booting from macOS recovery USB drive if you created one earlier and then repair and clean your original startup disk.
    2). Run disk cleanup and file system check in single user mode.

    Important Note :-  Disable SIP

    In order to fix grey screen startup problem, you may not be able to delete some unwanted stuff like unwanted applications, third party kernels(Kexts) or hardware drivers files or any other system protected files from recovery mode or Single user mode(SUM). This is because, starting from OS X El Capitan ver 10.11, Apple introduced a new feature called System Integrity Protection ( SIP, also knows as rootless) which actually prevents anyone from editing, deleting or moving any system protected files including kernel extensions( kexts) or hardware drivers. If you need to edit or delete them you must disable or turn the SIP feature off.

    To Disable System Integrity Protection:
    Disable SIP to make changes to System files
    Disable SIP to make changes to System files in case of no boot situation like grey screen with Apple logo

    #8. Run file system Check in Single User Mode

    Single user mode is a stripped down version of your real macOS which boots a Mac into minimal environment with basic OS kernel, and the processes for normal graphical interface, most of the system daemons and network services does not run. It actually boots the Machine from the original macOS partition ( Root Partition or default Startup Disk) and not from the recovery partition. In SUM, your Mac is booted with default superuser account known as root and does not require any password. However, If you have the FileVault enabled, it shows a login window before loading the single user environment and ask for the administrator password who encrypted the hard drive using FileVault. If you want to verify the name of startup disk or the disk name your Mac booted from in single user mode, simply type the following command when you get to the command line prompt saying root#.

    localhost:/ root# system_profiler SPSoftwareDataType

    To boot a Mac in SUM, Simply turn on or reboot it and immediately hold down ' Command + S ' keys at the same time. Continue holding the keys until you see white text line scrolling on black screen. Now wait until all the text line is done scrolling past and you see the command-line prompt saying "root#". 

    Now type the command "fsck -fy" to check and repair the file system on startup disk.
    File System Check and Repair
    File System Check and Repair in SUM
     The command will start checking the file system and go through five different checks which may take several minutes to complete. Once completed, it would show one of two messages: "FILE SYSTEM WAS MODIFIED" or "The volume [Boot Volume Name] appears to be OK" If you get the first message saying file system was modified then run the same command again and keep running it until you get the message "The volume [Boot Volume Name] appears to be OK."
    File System Check in SUM in case of Mac boot processes stuck on loading bar
    File System Check in Single user Mode in case of Mac boot processes stuck on loading bar
    Once you get to the second message saying the volume appears to be ok, type "reboot" and wait to see if computer boots successfully.

    Note:- In this mode the boot disk isn't fully mounted. So in order to fix various other issues with startup disk you need to first mount the disk in read / write access mode. Type the following command to enable write access.
    mount -uw /

    If it is still stalling at grey screen with Apple logo during boot then restart your Mac in single user mode and type the following command to clear boot caches, third party kexts (kernel extensions) and driver.

    mount -uw /
    rm -rf /System/Library/Caches/*
    rm /private/var/db/BootCache*
    rm -rf /Volumes/"Macintosh HD"/Library/Caches/com.apple*
    reboot

    If this reboots your Mac successfully, it means that the Mac is fixed and does not require any further troubleshooting but if it's still getting stuck at grey screen with Apple logo then follow the next step to find and remove incompatible kernel extensions ( kexts) using terminal in recovery mode.

    You can also do the other disk clean up and maintenance task in here if the Mac is unable to boot in recovery mode or if it does not have recovery partition. Both the SUM and the terminal in recovery mode accept same commands for cleanup and maintenance task, the only difference is the boot disk. Single user mode boots from original startup disk while the system recovery boots a Mac from recovery partition. So, in case your Mac is unable to boot due to low disk space, then boot it to SUM and delete logs, caches, unwanted applications, unwanted files, folders, or videos from different locations like (Desktop, Documents, and Downloads).

    #9. Remove incompatible Kernel Extensions (.kexts) and third party drivers

    As mentioned in step 3, if your Mac is still stalling or getting stuck on Apple logo with a loading bar due to an incompatible kernel extension(kext) or driver that is unable to load, then try to find the problematic kext or driver by booting your Mac in verbose mode. Once you have found the problematic kext, or you have already tried all the above steps, boot your Mac in recovery mode and start terminal to remove those problematic kexts or drivers. if you are unable to boot in recovery mode then try single user mode.

    If your Mac can boot into recovery mode:

    1. Boot into recovery mode and open terminal window as mentioned in step 7.
    2. Type "ls /Volumes" to list all the mounted volumes or partitions.
    3. Note down the exact name of your normal startup disk, in most of the cases it is named as " Macintosh HD"
    4. Now type ' cd /Volumes/"Macintosh HD" ' and then type " ls " to list all the folders and directories.
    5. Now create a new folder/directory to  move the problematic kext and driver into it so that they are backed up, just in case you need them. Type the following command.
    mkdir /Volumes/"Macintosh HD"/kextbackup

    6. Now navigate to the folder where all the kext and drivers are stored and list them to find any third party unwanted extensions and drivers.
    cd /Volumes/"Macintosh HD"/System/Library/Extensions
    ls

    7. Now here you will see a list of all the third party kexts and drivers and you can delete those you don't need or those you can download again, for example kexts or drivers for printers, scanner, camera, wireless card, USB data card, fingerprint reader, kexts or drivers for third party sound mixing device, etc.

    Some of the users have reported that they have got this issue fixed after removing some kernel extensions from previous version of OS X which were related to hp printer drivers, some USB to serial drivers, Cisco drivers, Huawei Data card driver, etc. here are the list of some incompatible or problematic kexts which were reported by different Mac users on different online support forum.

    If you find them in the list of installed kexts on your Mac, it is recommended that you remove them from the following locations.
    /Library/Extensions
    /System/Library/Extensions
    /Library/StartupItems

    Notes:-
    1. You must disable the System Integrity Protection(SIP) as mentioned above, before you can edit, move, or delete any kexts or system protected files.
    2. If you are confused and not sure what to remove and which one could be the problematic one, then simply move or delete all those kext which are not from Apple. Remove all the third part kext leaving only default kext or drivers which are installed with a fresh macOS installation. Just make sure that you do not move any of the kexts file whose name begins with APPLE*.kext or IO*.kext. For your convenient, here is a list of all the default kext in /Volumes/"Macintosh HD"/Library/Extensions/ folder on macOS Sierra. This is the list I prepared from my Mac after fresh macOS Sierra install.

    8. Now you have the list and you can find the third party kext, so just move the third party kext into kextbackup folder. To move a particular third party kext, use the following command.

    mv KEXTNAME.kext /Volumes/"Macintosh HD"/kextbackup/

    Once you have moved all the unwanted kext and drivers, try to reboot your Mac and see if it boots successfully. Type the command "reboot".

    Try Single user mode if your Mac can't boot into recovery mode:

    1. Try booting into Single user mode as explained in Step 8.
    2. Create a kextbackup folder and move the unwanted kexts and drivers into it. Use the following commands.

    mount -uw /
    cd /System/Library/Extensions
    ls
    mkdir kextbackup
    mv KEXTNAME.kext kextbackup
    rm -rf /System/Library/Caches/*
    rm -rf /Volumes/"Macintosh HD"/Library/Caches/*

    3. Type "reboot" to restart it normally. If is still does not boot and stuck on Apple logo with a loading bar then move on to the next step.

    #10. Reinstall macOS

    If you have already tried all the steps mentioned above and your Mac still stuck on Apple logo with a loading bar then it's time to reinstall macOS Sierra. Simple re-installation of macOS Sierra does not harm any of your file or data until you do clean re-installation. Reinstallation of macOS will also fix issues with the system files if they are corrupt or damaged.

    To Reinstall macOS Sierra:

    Restart your Mac and hold down "Cmd+R " together until you see grey Apple Logo. Make sure you're connected to the Internet, select your preferred language from the list and click continue. Select "Reinstall macOS " and click "Continue." Follow the onscreen instructions to complete the installation.

    #11. Restore from Time Machine Backup

    If you have already tried reinstalling macOS and the Mac still does not boot then try restoring it from Time Machine backup as mentioned here. Restore it to an older date when it was working perfectly fine and the date after which you have successfully restarted your Mac. Restoring from Time Machine backup actually erase your whole disk first and then copy everything from backup disk.

    #12. Clean Reinstall macOS or do Internet Recovery

    If normal re-installation does not work and you do not have Time Machine Backup then the only option for you is do clean installation or internet recovery.
    Please note that all the data on the hard drive will be erased in the following troubleshooting so you are required to take backup if you have any important data on the Mac. You can copy data to an external hard drive using terminal command or SUM or Install macOS on an external hard drive then boot from the external hard drive and copy data from your Mac over to the external drive. Once the data have been copied, erase the external hard drive and reinstall macOS as mentioned in Step 10.

    If for some reason the internal drive has corrupt file system and does not allow you to reinstall macOS to an external hard drive. You can do internet recovery and boot it directly from Apple' server.
    To boot your Mac from Internet Recovery:
    • Turn off the Mac. 
    • Turn it back on and hold down "Option+Command+R" key immediately. Keep them held until you see a moving earth icon.
    • If it ask to connect to a WiFi network. Select your home network and connect.
    • Make sure the power adapter is connected in case its a MacBook.
    • Once the recovery information is loaded onto your Mac, you get the macOS Utilities option where you can select "reinstall macOS" and the external hard drive as the destination.

    #13. Check for hardware issue

    This is going to be the last resort to fix the issue - Mac stalling at grey screen with Apple logo. Sometimes low physical memory(RAM), faulty hard drive or lose connection to internal hard drive, or a faulty video card also causes your Mac to stall at boot. If you have already tried all the steps mentioned above and nothing seems to be working and you really need to buy new stuff then try the following steps.

    1. Increase the memory (RAM)
    if you just have 2GB RAM installed. If you have 4 GB of RAM and you run software or application that has higher memory usage like Adobe Photoshop, AutoCAD etc. then consider upgrading the memory to 8 GB.
    Here is how you can upgrade memory in your MacBook. If it's a MacBook Air then I would recommend you to take it to any nearby Apple Store.

    2. Disconnect and Reconnect the hard drive
    When you open the back cover of your Mac to upgrade the Memory, at the same time, also disconnect and reconnect the internal hard drive to make sure it doesn't have any loose connection problem.

    #14. Check the Video Card for any Fault

    There are few iMac and Macbook Pro model which had known issue with Video Card. Apple had accepted the fault and also conducted a recall program for the affected model.

    This issue was first time detected in 27-inch, Mid 2011 iMac model with 3.1 GHz quad-core Intel Core i5 or 3.4 GHz quad-core Intel Core i7 processors and AMD Radeon 6970 Video Card. This recall program has already ended and is no longer available but if you have the same iMac model and it wasn't replaced by Apple then you should take it to the store for out of warranty repair which may cost you hundreds of dollars.

    Another Similar recall program is still available for MacBook Pro (Retina, 15-inch, Mid 2012) and MacBook Pro (Retina, 15 inch, Early 2013) which were manufactured between Mid 2012 and Early 2013.

    Here are the Symptoms in affected model:
    • Black screen or no Video on the computer screen(or external display) even though the computer is on
    • Scrambled or distorted video on the computer screen
    • Computer restarts unexpectedly
    The program covers affected MacBook Pro models until four years from its original date of purchase. You can check the eligibility for free repair or replacement of your MacBook pro on this page.

    If your Mac model doesn't come under the recall program and you get this far, I'm sure you are dealing with a hardware fault and you should make a "Genius appointment" at any nearest Apple store.
