• Corrupted Files: During the update process, certain files may become corrupted, preventing the system from booting.

• Interrupted Update: If the update was interrupted due to power loss or other issues, it may leave the system in an unstable state.

How Can You Troubleshoot the Mac Won't Boot After High Sierra Update Holding Problem?

If your Mac is struggling to boot after the High Sierra update, follow these troubleshooting steps to identify and fix the issue:

1. Perform a Safe Boot

Starting your Mac in Safe Mode can help diagnose the problem. To do this, follow these steps:

1. Shut down your Mac completely.
2. Turn it back on and immediately hold down the Shift key.
3. Release the Shift key when you see the login window.

If your Mac successfully boots in Safe Mode, it may indicate that a third-party app or extension is causing the issue. You can then try uninstalling recently added applications or updates.

2. Reset NVRAM/PRAM

Resetting NVRAM (Non-Volatile Random Access Memory) can help resolve boot issues. Here's how to do it:

1. Shut down your Mac.
2. Turn it on and immediately hold down Option, Command, P, and R keys simultaneously.
3. Keep holding these keys for about 20 seconds, then release them.

This process resets the settings stored in NVRAM, which may resolve boot issues related to display resolution, volume settings, and more.

Is It Possible to Repair the Startup Disk?

If the previous steps did not resolve the issue, you may need to repair the startup disk. Here’s how:

1. Use Disk Utility in Recovery Mode

Follow these steps to access Disk Utility and repair your startup disk:

1. Shut down your Mac.
2. Turn it on and immediately hold down Command and R keys.
3. Release the keys when you see the Apple logo or a spinning globe.
4. Select Disk Utility from the macOS Utilities window.
5. Choose your startup disk and click on "First Aid" to run a repair.

2. Reinstall macOS High Sierra

If repairing the disk doesn’t work, you may need to reinstall macOS High Sierra. You can do this from the same Recovery Mode menu. Make sure to back up your data if possible, as this process may result in data loss.
