iMac mid 2014 has been working fine for 5 years (well, sort of since I made the mistake of upgrading to Catalina).
As of today:
- start the mac
- select a user from login screen
- enter password
- A few seconds elapse and then the cursor changes to the spinning colour wheel
At this point the UI is frozen. I have tried leaving it in this state for 24 hours to see if it clears, it does not.
While in this state I can SSH into the mac and
sudo kill -9 the login window daemon to get back to the user selection screen.
Tried so far:
- Safe Mode login - same result
- Safe Mode boot - same result
- Reinstall MacOS - same result
- SMC Reset - same result
- Disk Utility fschk - no problems found
- Macbook Pro stuck after I enter my password: I deleted csstore but no help.
- My Mac gives me a black screen after logging into one account, but not another: Created a new user in the terminal via ssh. Same issue, can’t log in.
If I can I'd like to avoid having to backup data via scp, wiping the disk and reinstalling from scratch - I've got better things to do with my life.
I also have no intention of visiting a Mac Store only to be told my a smug child that he's going to wipe the disk and reinstall.
Someone out there must know what specific breakage Apple and snuck in via auto update the night before and how to undo the damage, surely?
