Updated imac with Mac OS update and now it’s back to screen to sign in but keeps spinning
Should I manually restart computer?
iMac 21.5″, macOS 10.15
Question marked as
Yes, you'll have to.
Try this on next power on...
Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.
Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.
