Installed 11.1 on an M1 MBA 8/512. It fixed a particularly irksome bug that manifested itself when I was playing StartCraft II fullscreen on an external monitor where SC2 is running at a lower resolution than what I have my external monitor Desktop set to. When I switched back to my desktop screen on the external monitor while I was playing a game, the dock would place itself in the middle bottom-third of the screen, as if it were misinterpreting the resolution. For instance, normal desktop set to 2560x1440, SC2 running at 1920x1080. A task switch between the two would result in a somewhat scrambled desktop with the dock sitting in an odd location. Now, everything works fine. Good job Rosetta 2. Also, these M1 macs switch between fullscreen games and the desktop much more quickly than my Intel macbook. The intel macbook as a sort of delay that blanks the screen before making the switch. The M1 has no delay.
