Since I updated my MacBook Pro from Catalina to Montetey, I can no longer play my games under Big Fish Game Manager. How do I uninstall the Monterey update and will this fix the problem

First off all you can’t uninstall macOS Monterey second your game probably needs an update by its developer to be run on Monterey , try to delete the app then reinstall back on

I have the same problem. I have contacted Big Fish games and alerted them that macOS Monterey is incompatible with Big Fish game manager. I have uninstalled game manager several times. Completely removed the game, checked the hard drive that it's completely gone, emptied the trash and reinstalled. still doesn't work.

Big Fish has just updated their Mac game manager, but clearly not compatible with macOS Monterey. I get so annoyed when this consistently happens with apple macOS upgrades to any number of programs.
