When playing rise of nations on my 2.4 Ghz 4gb ram Intel Mac, I decided to detonate a nuclear device on the hapless Lakota. However, as soon as the bomb went off, all of the terrain went black and so did the interface. I tried playing a different kind of game, and I downloaded the 1.0.1 patch, but still nukes are failing. Does anyone else have this problem? If so, have you fixed it? Thanks in advance.
