Hi, I’m hoping someone might be able to help. I followed Dr Macintosh’s tutorial video to upgrade to Monterrey from Big Sur.

Things went well up until the point where it asked me if I wanted to back up from Time Machine, which I did. Once I did this and it said it would take a few hours I came back to the Apple logo and the progress bar stuck around a third of the way.

Whenever I try to reboot the same thing happens. I’m not sure what to do as the video doesn’t say anything about this and I’m scared to make a wrong move at this point. Any help would be much appreciated! Thank you
