I'm trying to play Black & White, but when I click on the icon, the screen flickers for a moment, then says "Black & White could not initialize the display on this machine. Please switch to an 800x600 resolution and try again." I've tried both the 800x600 regular and stretch options under System Preferences|Display, I've tried reinstalling and restarting the computer, but still nothing. I have an external display I could try running it on, but I don't have an adapter that's appropriate. I'm running it on a late 2007 Macbook, 2.2 Ghz, 4GB RAM.
