Fix White Screen On Mac. So you have turned on your Mac and all appears is a white screen? Well we have a fix.
Why is this happening?
If a plain white screen appears when your Mac starts that means some of its hardware or software may have failed.
1. Check your Mac’s hardware systematically.
To find the device causing the issues start by disconnecting everything from it, including audio jacks, usb cables etc. After you have done that, restart the Mac and see if the white screen reappears, if the white screen is not going try resetting the PRAM.
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. Let us know in the comments if this helped.
2. Reset PRAM
Parameter Random-Access Memory (PRAM) and Non-volatile Random-Access Memory (NVRAM) store configuration information about your Mac. 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. |
If your Mac has multiple drives, you might need to select a start-up disk after resetting your Mac. If your Mac starts normally, then you can skip the instructions below. However, if you must select a start-up disk:
|
▪ Restart your Mac, then press and hold down the Option ▪ In the Startup Manager, use the arrow keys to select the main drive (usually called Macintosh HD), and then press the Return ▪ Wait for the Mac to finish starting up. |
After your Mac successfully starts, go to System Preferences and adjust any settings that changed. You might want to do some maintenance to prevent an issue like this from happening again, go ahead and check out CleanMyMacX.
