How to Fix a White Screen After Updating Software on Mac
If you have updated your software on Mac and encountered a white screen problem, you are not alone. Many Mac users have reported this issue after installing macOS updates or security patches. A white screen usually means that your Mac cannot boot up properly and is stuck in a loop. Fortunately, there are some solutions that you can try to fix this problem and get your Mac back to normal.
Before you start, make sure that your Mac is plugged into a power source and has a stable internet connection. You may also want to back up your important data using an external drive or iCloud if possible. Here are some steps that you can follow to fix a white screen after updating software on Mac:
Restart your Mac in Safe Mode. Safe Mode is a diagnostic mode that prevents some software and drivers from loading, which may help you troubleshoot the problem. To restart your Mac in Safe Mode, press and hold the Shift key as soon as you hear the startup sound or see the Apple logo. Release the Shift key when you see the login screen. If you can log in successfully, check if the white screen problem is resolved. If not, proceed to the next step.
Reset the NVRAM or PRAM. NVRAM or PRAM is a small amount of memory that stores some settings such as sound volume, display resolution, and startup disk. Sometimes, resetting the NVRAM or PRAM can fix issues related to booting up your Mac. To reset the NVRAM or PRAM, shut down your Mac and then turn it on again. As soon as you hear the startup sound, press and hold the Option, Command, P, and R keys together for about 20 seconds. Release the keys when you hear the startup sound again or see the Apple logo. Check if the white screen problem is resolved. If not, proceed to the next step.
Run Disk Utility in Recovery Mode. Recovery Mode is a special mode that allows you to access some tools and features that can help you repair your Mac. One of these tools is Disk Utility, which can check and fix errors on your hard drive. To run Disk Utility in Recovery Mode, restart your Mac and press and hold the Command and R keys together as soon as you hear the startup sound or see the Apple logo. Release the keys when you see the macOS Utilities window. Select Disk Utility from the options and click Continue. Choose your startup disk from the sidebar and click First Aid. Click Run to start the repair process. When it is done, click Done and restart your Mac normally. Check if the white screen problem is resolved. If not, proceed to the next step.
Reinstall macOS in Recovery Mode. If none of the above steps work, you may need to reinstall macOS on your Mac. This will erase your hard drive and install a fresh copy of macOS on it. Make sure that you have backed up your data before doing this. To reinstall macOS in Recovery Mode, follow the same steps as above to enter Recovery Mode. Select Reinstall macOS from the options and click Continue. Follow the on-screen instructions to choose your startup disk and agree to the terms and conditions. Wait for the installation process to complete and then set up your Mac as new. Check if the white screen problem is resolved.
If you still have a white screen after updating software on Mac, you may need to contact Apple support or visit an Apple Store for further assistance. There may be a hardware issue that requires professional repair. aa16f39245
