Overheating MacBook Air CPU

If you find yourself using a Macbook Air and wondering why it’s sometimes fast and sometimes slow, and almost always hot and spinning fans on high, check Activity Monitor. If one of your cores is black, you should call AppleCare.

After working with AppleCare all week, the overheating issue with Vinyamar’s CPU warrants a replacement or return. The core should not shut down, under any circumstances, especially not 10 minutes in to any video that I try to play.

So, back she goes. I’ll give the model another chance.

(Apparently, ‘limp mode’ is not actually a feature of the MBAir. Who knew?)
