Hello, after upgrade from catalina no major problem. Except that it is impossible to start in safe mode (crossed out circle then extinction). MacBook pro 13 "mid 2012.

Assuming you're telling about this:

  1. Turn on your Mac again (in Normal Mode) after 30 seconds of waiting.
  2. Download this file.
  3. Extract the ZIP file.
  4. With Terminal opened, execute the following command (Warning: Don't use Finder to do this): 
    sudo mv <path_to>/PlatformSupport.plist /System/Library/CoreServices/PlatformSupport.plist
  5. Restart your Mac (to Normal Mode) for the changes to take effect.
  6. Try booting into Safe Mode.
