i think mine is on the last stage of installation and it froze I don’t know what to do, it was frozen for like 20 minutes. And then I called Apple and they said to wait since a lot of people are downloading Mac OS big sur at the same time. I’m going to wait another 30 minutes and if nothing works then I will call them back.
