I searched, but was unable to find a similar thread for this issue.

I have obtained the game through Steam and am running version 2.1.65. I was able to get this to successfully run earlier today on my MacBook Air, but when I got home and tried to launch on my 2009 Mac Mini I just get a white screen and the spinny wheel of death. Eventually it shows up as not responding in the activity monitor.

Has anyone else experienced this issue? I'll gladly upload any necessary logs or information, just not sure how to go about that. I found a thread that linked me to another thread indicating it would have instructions, but it was just a beta release notes thread.
