I have been playing the Windows version on my Bootcamped mac. It works OK. Today just as a test I downloaded the latest Unity version and tried to start that. No go. After hitting "Play" from steam, I get a red screen. It doesn't recover or start the game. I am running Catalina 10.15.7 on a macbook pro, maxed out ram and adequate graphics card. When I tried to run the demo about 6 months ago, it did run, but was super laggy and unplayable.
Possibly it doesn't like that version of OSX. I'm not updating yet.
Not a big deal for me as I can play on the Win side, but I wonder if the Mac version is running yet? Thx.
