I have four systems: A 5-year-old MacBook Pro, a 4-year-old iMac desktop, a 5-year-old iMac Pro Desktop, and a new MacBook Air with the M1 chip. All upgraded fine except the 4-year-old iMac desktop (the non-Pro version). I've had all kinds of problems with it since upgrading including dreadfully slow response, the black screen of death, iMessage works intermittently, etc. I ran Clean My Mac several times and it seemed to help, and it seemed to get better with time - yeah, I know, very odd. I upgraded two months ago and I just decided this morning that I'm going to rebuild the whole thing from the ground up. The performance isn't acceptable and I've hit all the Mac forums trying to figure out what might be wrong, but it seems to be all over the place. Note that this system is Intel-based. I haven't seen any problems on any of the forums with the M chip systems. Good luck!
