When you Apple laptop goes full unresponsive and remains stuck on a blank white screen displaying an error, it’s usually your phone that you grab to quickly google for a solution. These kinds of issues are always uncalled for which means finding a fix becomes a matter of immediate importance. Finding articles that keeping beating around the bush for ages only adds up to the stress. So without any further ado, let’s get down to it!

What is the Mac White Screen of Death Issue?

Macs, whether it’s a MacBook Pro, Air or an iMac, have always been associated with reliability and performance to match. However, even with a reputation as strong as Apple’s, their computers do need an occasional fix. White screen on Mac — aka white screen of death — is an issue that causes your Mac to get stuck at a boot up screen preventing your computer from loading the OS.

You will often find this occurring after updating macOS to a new version, installing incompatible drivers, or a major app update installs incorrectly. This causes your Mac to be practically unusable. Luckily, there are a few fixes you can attempt yourself.

How to Quickly Fix MacBook Stuck on White Screen

Your very first step to resolving the Mac startup screen issue is actually quite simple. Begin by disconnecting all of the peripherals from your Mac computer. If you have a MacBook Pro or Air, then eject all USB devices, printers, scanners, etc. If you happen to run into the white screen issue on an iMac, then make sure to disconnect everything except mouse and keyboard, you are going to need those.

Reboot you Mac once external devices are unplugged. If it successfully boots up, then the issue is caused by one of the peripherals. Try reconnecting them one at a time to figure out which one was causing the trouble.

What to Do When MacBook Boots to White Screen?

Unfortunately, most of the times the problem isn’t as easy to deal with. If upon disconnecting all peripherals your MacBook Pro still fails to load, then you are going to need to try other options.

Boot your Mac into Safe Mode

Safe mode was specifically integrated into macOS with the purpose of troubleshooting.  With the help of safe mode, you can initiate a disk scan to determine and repair possible errors. Booting into safe mode should be your go-to action if, for some reason, your Mac does not turn on. Follow these steps:

  • Hold Shift key immediately after pressing the Power button
  • Release the Shift key after you see an Apple logo on your screen

Once in safe mode, the thing you are going to want to do is erase cache. Rebooting to safe mode will automatically clean some of the cache, however, it is still recommended to erase all cache you can find. Cache houses temporary data, which is meant to help things load faster. Occasionally though, cached data may get corrupted or simply outdated and cause performance issues or other errors. You can look up ways to clear cache manually, yet for the sake of making this quick, it is recommended you download MacFly Pro.

  • Install the app and run a System scan.
  • Select caches and click Clean Now

Reboot your Mac to see if clearing cache had solved the problem.

Reset PRAM/NVRAM

Another viable solution is resetting parameter or nonvolatile random access memory on your Mac. PRAM/NVRAM is the kind of memory your Apple computer uses to store certain settings like volume level, time zone, startup disk selection, etc. Resetting these parameters can put your Mac back in shape. Follow these steps:

1.           Shut down your Mac

2.           Hold Command-Option-P-R until you the startup sound

3.           Release the keys

Don’t forget to adjust your settings in the System Preferences after your Mac boots up.

Verify & Repair Disks with Disk Utility

Startup disk can also be the source of the problem. Luckily, Disk Utility can fix most of disk-related problems, including the ones that cause Mac to get stuck on white screen.

Here is how you can use Disk Utility:

1.           Power up your Mac while holding Command-R keys

2.           Release the keys, when Apple logo shows up

3.           Select Disk Utility and click Continue

4.           Choose the disk to repair and hit First Aid

Disk Utility will determine and fix the issues your drive may be running into. Exception being when your disk is about to fail, which is one thing Disk Utility can’t fix. In this case, you should be looking into replacing your drive.

Reinstall Fresh Version of macOS

In case all other methods fail to resolve the issue and your Mac still does not boot up past the white screen, your last resort would be to perform a fresh OS install. In fact, reinstalling macOS is not difficult even for an ordinary user.

1.           Shut down your Mac

2.           Turn it back on holding down Command-Option-R until the Apple logo appears

3.           Choose Reinstall macOS and hit Continue

4.           Select your Drive and click Install

5.           Follow onscreen instructions

This should definitely get your Mac intact again. However, to prevent such errors from reoccurring, you should start maintaining your computer regularly. Instead of trying to do everything on your own, opt for trustworthy software for the sake of speed and safety.
