Hi friends, If you launch the game on OSX today, you might see a small download in Steam/Epic, but no change in the game version number.  We've notarized the build for the tighter security restrictions on OSX Catalina (10.15). The game itself hasn't changed in any way.  We're also aware of some issues that exist on Catalina at the moment. Some of these require Unity and drivers to publish updates, but we're working on the problem and hope to have it smoothed out soon. Thanks!
