So I got C&C, First Decade from Best Buy. It's the first 12 games in the series. I can't play any of them. I have Snow Leopard, installed Parallels, and installed XP Pro... SP2 or 3. I don't remember. With the earlier games such as Red Alert 1, I get an error message: Unable to allocate primary video buffer Red Alert 2 will start to play but no mouse action and no video... just sound With Generals it will not boot at all. I'm guessing there is a communication error with the games and hardware on my mac. Things I've tried: patches (including XP patch you get from the free download of Red Alert 1), properties>compatibility>win95 what I have: OS X 10.6.8 NVIDIA GeForce 9400M Anyone got a clue?
