Yes it does do the same thing for both computers. Otherwise I might be inclined to think it might be the sound hardware as the mac has Realtek Hi def audio card. Ill try the graphics thing. I can set the program to use specific graphics preferences so ill give that a go. And Yes I get the same issues with both fullscreen and windowed mode except with windowed mode i can force quit the program. Most times, in full, it crashes in such a way where the program manager won't pop up. EDIT: Nope still crashed this time right after I had finished talking with hobbs on the the first mission and i clicked the elevator. It also should be noted that, afterward, when I click on the WC3W.exe profile on my NVIDIA settings that programs crashes as well I had pretty much turned off all options except "negative LOD bias" i set to "allow" and "Multi-display/mixed-GPU acceleration" i set to "single display performance mode"
