The Warcraft game background colors are all neon bright -- yellow and pink and lime green. I did a disc repair, and all is well with the mac. I have OSx10.6.8, and have never had a problem before the patch. I uninstalled everything and downloaded it again from Blizzard. Same problem. Can't play like this. Any suggestions?
After some sleuthing, I discovered the Blizzard site that lists the supported and unsupported graphics cards. The graphics card in the mac mini is not supported. So that is the problem. Unfortunately, the solution is to upgrade the system. You can't put in an upgraded graphics card in a mac mini. Oh well.
