Fix The White Screen Error On Mac: Won’t Start Or Boot

In this article, we have mentioned a list of viable fixes that can help resolve the White Screen error on Mac.

Unlike Windows, the bugs and issues on Mac are not that frequent, but this does not mean that you will not encounter any problem on your Mac ever. Some issues on Mac, when they occur, are sources of worry, and one of them is the Mac stuck on the white start-up screen issue. This issue is also referred to as the white screen of death on your Mac.

While this problem may seem horrific to the Mac owners, it is one of the most common problems you ought to encounter on your Mac. Recently, I was one of those unfortunate Mac owners who saw a completely white screen on the Mac after the startup sound. After that, there was no other start-up indication- no Apple logo appeared on the screen nor any progress bar.

If you are someone who recently encountered a similar situation on their Mac, you’re at the right place. In this article, we will try to troubleshoot this white screen error on your Mac which prevents it from starting or rebooting. Let’s get started.

Reset PRAM or NVRAM

If you had no luck until now, it’s time to reset your PRAM and NVRAM of your Mac. For the uninitiated, PRAM (parameter random access memory) or NVRAM (non-volatile random-access memory) is a tiny portion of the computer’s memory responsible for storing a few settings accessible by macOS. These settings can range from the speaker volume, screen resolution, startup disk selection, and any other kernel panic-related details.
So if you are experiencing the white screen issue on your Mac, it’s time to reset your PRAM or NVRAM.

Hopefully, you were able to resolve your white screen error on your Mac. If not, it’s time to reboot your Mac in Verbose mode. When your Mac will reboot in verbose mode, all the boot-related information will appear on the screen, generally hidden from the users.
This information will be useful for troubleshooting the white screen error on your Mac. Follow the steps given below to reboot your Mac in Verbose mode:
