Re: is sims compatible with macOS catalina version 10.15.4

@Jbwn5  Sims 4 is already compatible with Catalina, and has been since October.  If you'd like to know how your computer might be expected to handle the game, feel free to post in the Sims 4 Mac forum and list its specs:

Sims 3 doesn't run in Catalina, but there will eventually be an update that makes the game 64-bit-compatible.  You can keep an eye on this thread for updates:

The version of Sims 2 in the App Store is compatible with Catalina—Aspyr released an updated version a few months ago.  As for other Sims games, they don't run in Catalina, and there has been no indication that this will change at any point.
