How to Fix Mac Stuck on White Screen
If your Mac is stuck on a white screen, it is likely due to a problem with the display, graphics, or video circuitry. If you can’t seem to get your Mac to boot up normally, you can try these troubleshooting tips to get it back up and running.
First, try resetting the PRAM or NVRAM on your Mac. This can often fix simple software glitches that may be causing your Mac to get stuck on the white screen. To do this, shut down your Mac and then turn it on again. As soon as you hear the startup chime, hold down the Command + Option + P + R keys. Keep holding these keys until your Mac reboots and you hear the startup chime again.
If resetting the PRAM or NVRAM doesn’t work, you may need to try resetting the SMC (System Management Controller). This can often fix problems with the power, fans, sensors, and other hardware components on your Mac. To reset the SMC, shut down your Mac and then unplug the power cord. Wait for at least 15 seconds and then plug the power cord back in. Turn on your Mac and see if it boots up normally.
If your Mac is still stuck on the white screen, the problem may be with the graphics or video circuitry. If you have an external display connected to your Mac, try disconnecting it and then restarting your Mac. If your Mac boots up normally, the problem is probably with the external display. If you don’t have an external display connected, or if your Mac doesn’t boot up normally even with the external display disconnected, the problem is probably with the graphics or video circuitry on your Mac. In this case, you may need to take your Mac to an Apple Store or authorized service provider for repairs.

How to Fix Mac Stuck on White Screen
Restart your Mac
If you find that your Mac is stuck on a white screen, the first thing you should do is try restarting your Mac. To do this, simply press and hold the power button on your Mac for a few seconds until it powers off. Once it’s off, press the power button again to turn it back on.
If your Mac is still stuck on a white screen after restarting, you may need to try resetting the PRAM or NVRAM on your Mac. These are special settings that are used by your Mac to store certain information, and resetting them can often fix strange issues like this.
To reset the PRAM or NVRAM on your Mac, simply turn it off and then turn it back on while holding down the Option, Command, P, and R keys simultaneously. Keep holding these keys until you hear the startup sound for a second time. Once you hear the startup sound a second time, you can let go of the keys and your Mac should boot up normally.
Try Safe Boot
If you’re Mac is stuck on a white screen, one possible reason is a problem with your startup disk. To try to fix this, you can start your Mac in Safe Boot mode. This will help to rule out any software-related issues that might be causing the problem.
To do this, turn off your Mac and then turn it back on while holding down the Shift key. Keep holding the Shift key until you see the Apple logo. Once your Mac has started up in Safe Boot mode, try restarting it normally. If it works, then there’s likely an issue with some software that’s loading at startup. You can try to narrow down the problem by starting up your Mac in Safe Boot mode and then removing items from your startup items one at a time.
Use Disk Utility
If your Mac is stuck on a white screen and you can’t seem to get it to do anything, you may need to use Disk Utility. This is a built-in tool that can help you fix various issues with your Mac’s hard drive. To use Disk Utility, follow these steps:
1. Boot into Recovery Mode. This can be done by restarting your Mac and holding down the Command + R keys.
2. Once you’re in Recovery Mode, open Disk Utility.
3. Select your Mac’s hard drive from the list of devices.
4. Click on the First Aid tab.
5. Click on the Verify Disk button. This will check your hard drive for any errors.
6. If any errors are found, click on the Repair Disk button to fix them.
7. Once your hard drive has been repaired, restart your Mac.
Reinstall macOS
If your Mac is stuck on a white screen, the first thing you should do is reinstall macOS. This will remove any corrupt files or settings that may be causing the problem. To do this, follow these steps:
1. Restart your Mac and hold down the Command+R keys until you see the Apple logo.
2. When the menu appears, select the “Reinstall macOS” option and click Continue.
3. Follow the prompts to reinstall macOS.
If this doesn’t fix the problem, you may need to try a more drastic measure, such as resetting your Mac to factory settings.
Reset NVRAM or PRAM
If your Mac is stuck on a white screen and you can’t seem to figure out why, one thing you can try is resetting the NVRAM or PRAM. NVRAM is a type of memory that stores certain settings and information, and resetting it can sometimes fix issues like this. To reset your NVRAM, follow these steps:
1. Shut down your Mac.
2. Turn it on and immediately press and hold the Option, Command, P, and R keys. You must press these keys before the gray screen appears.
3. Hold the keys down until your Mac restarts and you hear the startup sound for the second time.
4. Release the keys.
If resetting the NVRAM doesn’t fix the issue, you can also try resetting the PRAM. PRAM stands for parameter random-access memory, and it stores similar information to NVRAM. To reset your PRAM, follow these steps:
1. Shut down your Mac.
2. Turn it on and immediately press and hold the Option, Command, P, and R keys. You must press these keys before the gray screen appears.
3. Hold the keys down until your Mac restarts and you hear the startup sound for the second time.
4. Release the keys.
If you’re still having issues after resetting the NVRAM or PRAM, you can try other troubleshooting steps, such as restarting in Safe Mode or resetting the SMC.
