MP mods that actually change the game code wouldn't work unless it's a version specifically for MACs; basically, if a mod ships with a dll file or one of the mod's pk3 files contains dll files (at the topmost level), it'll probably NOT work on a MAC.
Well that is good because I don't really care about MP all that much.
