I've only tried a few, but all of them except Auctioneer return some error value at some point while playing. The game never crashes, it's really only a minor disruption, but it's irritating, and one message popped up in the middle of a large fight. I"ve been careful about making sure the ones I've tried are both well regarded and tested on 1.6, but none of them seem to work totally as advertised. They function well enough to keep me interested in trying some, but I haven't found one to keep yet. Anyone use any mods that behave cleanly on a Mac? Any you find essential? My main character is a lvl 41 hunter, but I've also been dabbling with fighters, rogues, and warlocks.
