It is rare that a Mac sometimes may fail to boot and get stuck on a white screen. The users will usually discover the problem after updating system software. Where the Mac starts up but quickly halts on an all-white display. If in case, you observe that your Mac stuck on a white screen during boot and is not powering on as expected. Then you may think first of the troubleshooting method. So, have a look at the given below procedure and learn how to fix mac white screen issue:
We are discussing here of Mac that is stuck on an all-white screen with no progress bar. Nothing but just a blank white display. There are numerous causes for a white screen to appear on a Mac during startup. So, we’re going to discuss a handful range of troubleshooting methods that may resolve the issue. Steps are very simple and clear that is, simply reboot into Safe Mode. Now, reset NVRAM and fix the white screen issue.
Reboot into Safe Mode
So, just simply reboot into Safe Mode on the Mac with a properly timed
shift key press.
Rebooting the Mac and then immediately hold down the SHIFT key. The user sees the Apple logo and progress bar then, releases the “SHIFT” key.
Rebooting can be safe and easy and it can truly be the remedy for some simple issues with a Mac getting stuck on a white screen during boot, etc. It is the first solution that stuck in everybody’s mind. If the Mac works fine in safe mode, try rebooting again and see if it works as usual.
It is quite often seen that resetting NVRAM / PRAM is sufficient to remedy a white screen Mac issue, have a look at this method:
Rebooting the Mac and the moment you hear the boot chime. Then hold down the Command + Option + P + R keys simultaneously.
After that, if again when you hear a second boot chime. You can release the keys as the NVRAM has been already reset.
After the successful reset of NVRAM, go ahead with the further steps and let the Mac boot as usual. At this point, it should no longer get stuck on a white screen.
In this step we will focus on resetting SMC on modern MacBook Pro, MacBook, MacBook Air models:
The very first step is to shut down the computer and then connect it to your adapter and a wall outlet.
Second of all is to hold down the “Shift+Control+Option+Power button” at the same time for a few seconds and then release all keys concurrently.

The third step is to select the hard drive and then go to the “First Aid” tab and choose to run First Aid and repair the drive.
If error shown in the drive, that can’t be repaired. You may have an underlying issue or drive failure impending. In that case, be sure to backup your data from the Mac, and then consider apple hardware test and diagnose to solve the issue. Often replacing a hard disk is in order, some users are comfortable doing it themselves otherwise you might want to contact an Apple Support center.

Sometimes booting with verbose mode also works. So,
just quickly have a look at the steps:
Again, here also, we have to carry on the Rebooting the Mac as usual and then immediately hold down “COMMAND + V” keys.
It is just the general act of rebooting of Mac, yet again as verbose mode shouldn’t really do anything different aside from appearances. But it does seem to sometimes work to bypass a stuck white screen on some Macs.
Reinstallation of Mac OS
