High Sierra install is frozen
I’ve been running Sierra on a mid 2010 iMac - tried to upgrade to High Sierra last night. Download went fine - install seemed to be proceeding well. However when the bar was about 95% of the way across, it just stopped. Has been this way for about 10 hours now. Computer is getting pretty warm (hot). Would you just shut it down? How do I know if something is going on still? Would you shut it down and just try to restart it? Or would you first try to restart in Safe Mode?
Not sure what is going on, but not thrilled. I do have a Time Machine backup.
Thanks,
Mark
