We just recently purchased a high-end early 2011 13" macbook. I'm not experiencing the problem but trying to keep the wife happy. The problem is with cityville on facebook. After about five minutes safari hangs and she has to quit out of safari to get it to do anything. At first I thought it was temp related so I got istat. I noted that it was constantly around 90c and climbing when it would happen. So I installed fan control to make the fans turn on at a lower temp. This hasn't helped, it will still hang when the temps are around 88c. So I reset safari and repaired disk permissions. That didn't change anything. Even installed firefox which seemed to help until today. Anyone else had this problem or a word of advice that they could offer. I love the computer but my wife is beginning to wonder why we purchased it if she can't play her game. Thanks
