iMac frozen during update. What must I do to reboot
I normally sleep my iMac and login to use it the following morning except today I found it frozen i. The early stages of updating. What must I do to reboot or unfreeze?
iMac 21.5″ 4K, macOS 13.6
Force a Shutdown using the Power Button and until it does shutdown
Optional - the remove any External Drives
Wait maybe 1 minute
Restart the computer in Safe Mode.
This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts.
The boot up will be slow and can take some time - Normal.
Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance
Hopefully the update process may or may not complete , successfully 🤞
