Many users are reporting an update fail for macOS Monterey. There could be several reasons for this, and it will vary from one MacBook to the other. A list of macs compatible with Monterey is available on the Apple website.
Before you read further, it would be better if you just go through that list and see if your Mac is compatible according to them. However, if you are not using an old mac, trying to upgrade to macOS under normal circumstances will inevitably fail.
Therefore, you have to take an unconventional path to get the upgrade. I will link the blog post that will walk you through the process of getting Monterey on an unsupported Mac. Anyhow, if your mac year is included in the list, but you are still facing this issue, you’re in the right place.
In this blog post, I have extensively discussed a few methods that you can try out one by one and see if your Mac responds. So, let’s get right into it.

macOS Monterey Update Fail Method 1: Check The Internet Connection
For any major upgrades in the Mac or any operating system for that matter, it is vital to have a strong and stable internet connection. Downloading a heavy file like Monterey and installing it takes atleast an hour or two at the minimum.
During this process, your internet connection must remain stable and at high speed.
If that’s not the case and your network keeps dropping every now and then, your Mac will definitely interrupt the downloading process.
To rule that your internet connection is not the reason, do the following:
Step 1: Turn off Wi-Fi on your Mac.
Step 2: Then restart your Mac.
Step 3: After that, turn on Wi-Fi.
Step 4: Furthermore, now check if your Mac can download the update.
However, if the problem persists, change the Wi-Fi network as it can be possible that the Wi-Fi network is an issue. For example, you can connect your Mac to an Ethernet and then download the update.
macOS Monterey Update Fail Method 2: Remove Software Update Plist File
Step 1: Go to Finder on your Mac and tap on Go in the menu bar.
Step 2: Under the Go menu section, select Go to folder.
Step 3: In the Go to folder, type ~/Library/Preferences/ and click on Go.
Step 4: Mac will present you with a list of files. Here you have to scroll down and find com.apple.SoftwareUpdate.plist and delete it by dragging it to trash.

Step 2: Then select ‘About This Mac’ under the Apple Menu.
Step 3: Now select Storage Tab to see how much space is being used and how much is free.
Step 4: If your Mac does not have enough space to download the update, delete all unwanted files and apps from your Mac to free up space.

Step 6: Now, try to download the update.
However, if you are still getting the update failed error, then maybe storage is not the issue.

Method 7: Install Apple SSD And Get A DFU
A lot of MacBook Pro users are receiving a specific message that says MacOS a required firmware update could not be installed. Compatible internal storage is needed in order to update.
Keep in mind they are getting this message after they have tried all the above methods I have discussed in this blog post. Whether trying to free up space or booting in your Mac in safe mode, or even after an SMC reset. Moreover, many have also tried to use a bootable USB installer, after which this error message pops up.
In that case, I have a solution for that too. First, all you have to do is install an internal Apple SSD with an NVMe drive to update the firmware and operating system boot loader. Secondly, you can also try to install Monterey in DFU mode.
To install the Apple SSD, you should contact your nearest Apple customer care center. It is best to let the professionals take care of the complicated process. Moreover, they can decide better depending on the model of your Mac if you need an internal SSD or install from the device firmware update.
