Mac Mini 2014 Time Machine Freezing

I made a Time Machine backup before upgrading to Monterey, immediately knew it was a mistake as I couldn’t even use the browser without beach balls so last night I started the process of going back to my saved Time Machine backup.


it froze midway through, sat at the halfway mark for 8 hours and eventually I pulled the plug this morning after it sitting all night and making no progress - now I can’t load it at all, it won’t boot the loading bar gets to about 50% and stops so I can’t use the computer at all now.


tried going to the Time Machine backup it stops loading halfway, I’ve used disk utility to check for errors nothing, everything seems fine.


I tried to roll back to the most recent snapshot it says which is successful then won’t load and sits around 50% also tried loading a new copy of Monterey so at least I can use the computer in some capacity and nothing it doesn’t download just stops responding and I can’t seem to force it to load into safe mode either, this seems pretty bad.


any ideas please? I’d appreciate any help.

Mac mini, macOS 12.4

Sounds like the Mac Mini's hard drive is failing. You can try running the Apple Diagnostics to see if any hardware issues are detected. Unfortunately the diagnostics do not detect many types of drive failure. If the diagnostics do not report any problems, then I can provide instructions for checking the health of the drive by creating & using a Linux boot disk. If you have an external USB macOS boot disk (full install), then you can boot from it to use DriveDx to check the health of the drive.


FYI, when using First Aid, make sure to run First Aid on the hidden Container. Within Disk Utility you may need to click "View" and select "Show All Devices" so that the hidden Container appears on the left pane of Disk Utility. Even if First Aid says everything is "Ok", click "Show Details" and scroll back through the report to see if any unfixed errors are detected. If there are any unfixed errors listed, then try repairing it from Internet Recovery Mode (Command + Option + R), otherwise you will need to erase the whole physical drive before restoring from the backup.
