I have had my MBP for about two months now and it seems to be lagging a lot recently. I first noticed this when I would have a few applications open. The applications would freeze but eventually would return to normal. It seems like when the MBP gets hot (around 70 degrees Celsius) things start to freeze. My biggest concern is when I am typing something there is a definite noticeable lag. Since it is not happening all the time, (happens more when computer is hot but still happens when it is not) how will I show this to a mac genius? Is this a real problem that they will be able to fix??? thanks all!
