This is the first time I’ve had problems with an OS X upgrade to my Mac Mini (late 2012, supposedly ok with Catalina). The upgrade got part way through the “setting up your Mac” questions but has been stalled on the same screen for about six hours. The hard drive isn’t thrashing, and there are occasional non repetitive changes in seek activity so possibly it’s still running. (There was plenty of room on the drive.) I tried command-L to see the log but it just beeps. Didn’t see much about this in a google search. Thoughts?
