We must have the same iMac, igazor -- got mine the day after Pets came out (my old one conveniently picked that day to finally die). I Boot Camped Win7 on it and it plays it smoothly (well, with a little help from the good folks at NRaas :D ). Also handles the Sims 4 CAS demo well, as you can see in my avatar (which is me if I was about 30 years younger). I could probably go ahead and get Sims 4 and put it on there. But I'm still holding out hopes for a Mac version, plus I'm waiting to see what direction this game takes.
