Thanks for letting us know. Apple has basically made it impossible to get mac games to work properly on newer versions of macOS so there might not be much we can do about it. You might want to look into using Remote Play Detached with Steam (https://github.com/smaTc/RemotePlayDetached) or Parsec (https://parsecgaming.com/). Sorry for the super delayed response, we weren't getting email notifications for some reason. Stay slimy!
