I got a cheap MacMini late 2014 for a special task. Nice machine! Was delivered with Catalina, but I wanted to update to Monterey, which is the ultimate OS for that machine. So I do it, and on reboot, it gets stuck at the 1 minute mark. Sits there for a half-hour like that. I reboot, and I'm back at 29 minutes! I understand from posts on the web that this bizzarity is VERY COMMON, but there is no simple, obvious fix. Try this, try that, hope for this, pray for that. There must be ONE GOOD ANSWER. DO THIS AND IT SHALL WORK! Ideas, anyone?
