How do I fix the white screen of death?

Answer 1

There are a few options you can try to fix it. Go down the list starting with the first to see if it fixes the problem. If it does fix it, then you are good to use your computer, if not move to the next on the list.

First - To find a malfunctioning device attached to your Mac, start by disconnecting everything from it, including Bluetooth or other wireless connection. After you have done that, restart the Mac and see if the white screen reappears. If your Mac starts normally, then you can try reconnecting all of the devices one at a time until you find the one that caused of the problem. Replace that broken device.

Second - start your Mac in Safe Mode, follow these instructions:

Press the power button, and then press and hold the shift key when you hear the start-up chime.

Release the shift key when you see the Apple logo and progress bar.

Once the Mac has gone into Safe Mode, go to your Applications folder to uninstall the apps that you no longer use, then empty the trash.

Restart the Mac.

Third - Reset the Parameter Random-Access Memory (PRAM) and Non-volatile Random-Access Memory (NVRAM). To reset the PRAM/NVRAM, follow these instructions:

Restart the Mac, then press and hold down the Command + Option + P + R keys when you hear the start-up chime.

Continue to hold down the keys mentioned in the previous step until you hear the second start-up chime, then release the keys.

Wait for the Mac to finish starting up.

Fourth - Use the Disk Utility to make repairs by following these instructions:

Restart your Mac, then press and hold down the Command R keys when you hear the start-up chime.

Release the keys when you see the Apple logo.

When the OS X Utilities menu appears, click Disk Utility and find the drive that you want to repair.

Click the First Aid

fifth - Reinstalling the operating system should fix any corrupted software without deleting your data and files, but you should back them up first if possible. When ready, follow these instructions:

Restart the Mac, and then press and hold down the Command R keys when you hear the start-up chime.

Release the keys when you see the Apple logo.

When the Mac has finished starting up, choose Reinstall OS X from the OS X Utilities menu, then click Continue.

Follow the instructions that appear until you finish the process.
