Try now as it should be updated.
I just installed MOO2 clean on a brand new Macbook Pro 16 running Catalina. The installer works fine and the game opens without any error messages. However, the graphics are garbled to the point that you can barely make out what's on the screen. I figured maybe it couldn't handle the retina resolutions (though it worked fine on my previous MBP under older OSs), so I tried various lower resolutions to no effect. Has anyone gotten this working yet? Thanks.
