Welcome to EA's Mac port system - Cider. Cider is just... horrible. EA has no intention of fixing anything. My game crashes to desktop constantly because Cider only supports up to 2 GB of RAM.
He looks more realistic than about 97.5% of the TS3 "pudding face" sims. Considering that the goal of a life simulator is realism, I feel that you have done a good job.
] A glitch that is caused by mod conflicts? Yes, by uninstalling the mods. A glitch in general? Most likely not. EA ships TS3 with hundreds upon hundreds of glitches. Every patch/update released for the game adds even more.
If you don't have the dress in the game, regardless of the source, you can still download the sim, but the clothing will be replaced with the most similar object in game.
Doesn't matter to me. The game crashes so much with Cider that I barely even play it. But I'd have to go with fast game with little CC, because at times loading can be intolerable.
