A player named Growltiger believes he/she has found what's causing the problem, and has even devised a fix that's seemed to work really well for the people who've tried it. Blizzard's acknowledged this and is working on patching the issue as soon as possible.
In the meantime, I thought that, in addition to including Growltiger's solution here, it might be a good idea to run an article on how to fix and prevent heat problems with Macs. We write for a pretty computer-savvy audience here at WoW Insider, and odds are good you'll find some people in the comment section who really know their stuff. I won't claim to be one of them, but I hope some of the things that have worked for me will also work for you.
Even if you're a novice computer user, you should find a few tips here. However, if you're one of the players looking to implement Growltiger's fix, fair warning: It's not for the faint of heart.
