Apple has made the decision to stop support for 32-bit apps with the release of macOS Catalina (10.15).
What does this mean for my games?
With the recent Game Manger update, select games can be played on macOS Catalina (10.15), but downloads must be initiated in the Game Manger. If you have already updated your macOS, see these instructions for which games are compatible and how you can install them.
This is an interim fix and we’ll be back with more details when we have permanent solution.
How can I make sure I can continue playing my games?
To continue playing 32-bit games, do not update to macOS Catalina (10.15).
Will new games be compatible with macOS Catalina (10.15)?
We’ve released an interim workaround for select games. See these instructions for which games are compatible and how you can install them.
How can I know if a game is compatible with my macOS?
To make sure that a game is compatible with your macOS, we recommend trying out a free trial version of the game before purchasing it.
For more information about how to download a free trial version of a game, make sure to visit our Download a Trial Game help article.
Please note that if the trial version of a game doesn't run, the full game won't run either.
How can I know if my apps are 32-bit?
Apple is notifying customers when they are using an app based on 32-bit technology. This is done via a one-time alert that appears when you launch a 32-bit app.
In macOS Mojave, this alert appears once every 30 days when launching the app.
