The crash seems to happen randomly. I could be adding a road or zoning or scrolling across the screen and it locks up and crashes. Sometimes the cirt will run for ten tweenty mins before a crash and other times it dies 1 min into the game. There isn't a specific function i can point towards. I would love to avoid getting rid of the plugins as they are all part of a city that i have been working on for very long time, but I don't see any other options. Are intel mac users having much luck with Rush Hour in the first place? Thanks for any insight into this. Sim City is really the only game I play.
