I am a mac user. I don't play the sims 2 on it as much, cause lack of ram at the moment. So I ususally play on my pc.
But so far what I have played I have not ran into any bugs yet. Of course it doesn't have UNI yet, so you never know what is to come. But I have read and am under the impression that this stuff can be used on the mac version. I will have to add some and test it out for you.
