Sometimes problems during update installations happen because of your device not being optimized for the process. To avoid hiccups, make sure to get rid of junk files on your Mac using Outbyte MacRepair, delete any unused apps, and restart your computer before downloading the updates.

If you encounter problems such as a black screen after the High Sierra update, you can follow the troubleshooting guides below to restore your display and fix the update error.

Step #1: Boot into Safe Mode.

The first step in fixing update errors is to boot into Safe Mode. This makes sure that no third-party processes will get in the way of the installation.

To boot into Safe Mode, follow these steps:

1. Turn off your Mac.
2. Hold the Shift button, then press Power to turn it back on.
3. Release the Shift button once you see the Apple logo and the progress bar.

Step #2: Reset SMC and NVRAM.

After booting into Safe Mode, the next step is to reset the System Management Controller or SMC. SMC manages the video and external displays of macOS, so resetting it should be one of the first steps you should take.

To reset SMC, shut down your Mac, then hold down Shift + Control + Option, then press Power at the same time. When you see the light on your MagSafe adapter blink with a different color, that means that the SMC has been reset. Release all the keys and boot as usual.

While you’re at it, you might also want to reset your Mac’s system settings, which is very easy to do. Shut down your Mac once again, then turn it on while pressing Command + Option + P + R on your keyboard after you hear the startup sound. Wait for the second startup sound before releasing all the keys, then boot as normal.

After resetting SMC and NVRAM, check if you can download and install the High Sierra update without going into the black screen.

Step #3: Delete Old Update Files.

MacOS update files delete themselves automatically after being installed. But if the installation was not successful, then it is possible that the update files are still on your computer. If they are, you won’t be able to download a new copy of the update and macOS will always revert to the old update files.

You need to search for the old update files and delete them. If your update was downloaded completely, you should check the ~/Applications/ directory and look for a file with a filename in this format “InstallXXXX”, InstallHighSierra, for example. Delete that file and download the update from the Mac App Store again.

If you can’t find the file in the Applications folder, then the download has probably not been completed. If this is the case, you can also check the /Library/Updates folder.

If you can’t find it in any of the folders, search for the file via Finder. Type a part of the name of the file in the search box, then press Enter to start the search. Once you find it, delete the update file and re-download it via App Store.

Step #4. Delete Cached Data via Terminal.

If you’re having trouble shutting down or restarting your Mac and you’re stuck in a black screen loop, you can try deleting the cached data using the Terminal. To do this:

1. Launch Terminal from Finder > Utilities.
2. Enter these commands one at a time, then hit Enter after each command line:
   • rm -rf ~/Library/Caches/
   • rm -rf ~/Library/Saved Application State/
   • sudo rm -rf /Library/Caches/
   • sudo rm -rf /System/Library/Caches/
   • atsutil databases -removeUser
   • sudo atsutil databases -remove
   • sudo atsutil server -shutdown
   • sudo atsutil server -ping
   • sudo rm -rf /var/folders/

Restart your computer after executing these commands to see if you can now boot normally.

Step #5: Restore Mac to an Earlier Date.

If nothing works, you can restore your system to an earlier time using your Time Machine backup. Follow these steps to undo the changes and roll back to an earlier date:

1. Reboot your Mac, then press Command + R to boot into Recovery Mode.
2. Choose Restore From Time Machine Backup.
3. Click Continue.
4. In the Restore Your System window, click the Continue button.
5. Choose your Time Machine backup, then hit Continue.
6. Click on the most recent backup of your Mac, then click Continue to start the rollback.
