So I'm running the original Supreme Commander on the latest version of OS X (10.10.4) and the latest version of Crossover (14.1.4). I installed it from the CD/DVD and patched it per the patching "tip" listed. So far, so good. The game runs fairly well. At least until I get toward the end of the second campaign mission (I think it was called Snow Blind). I get to the part where you are tasked with defending your base and destroying the Aeon leader. It runs for an additional 5 minutes or so, give or take a few (I haven't really paid attention to how long it takes), and then it locks up hard. I tried twice, and both times it happened around the same time after the mission update. Each time I was doing something different. One time I was in the middle of building up forces, and the second time I was in the process of attacking the Aeon base.
Has anyone experienced this?
Any help would be appreciated since it seems that I can't proceed past this point in the game.
Thanks.
