On MacOs Big Sur When I first installed Parallel 16, I was able to launch it and log in as usual. I upgraded from Parallel 10 since it was no longer compatible with the last OS. Today, I went back and tried to Launch parallel 16 again and then now, the app launches but only shows the square icon "parallel desktop Starting..." and nothing else loads. What is the problem?
Okay, just to make sure I understand your problem correctly. You were able to install the Technical Preview of Parallels on your M1 Mac and you were able to install an ARM OS and both used to work?
