Late 2012 iMac Catalina stalled install
I started the update to Catalina yesterday afternoon and 22 hours later I am stuck at a "Estimating time remaining..." and a 3/4 progress bar from this AM. I hear it can be slow but this has not moved. Not sure if I should just let it go or if I need to intervene in the process. I do not want to lose it all even with a time machine back-up. Any thoughts?
