Hey guys just picked up a macbook pro a week ago and twice now it has just shut down for no reason. Both times I have been using it and it just turned off, I looked around and it seems that it is not unheard of this problem happening since Yosemite, does anybody else have this problem? If so did you fix it or should I just wait for El Capitan and see if that fixes the problem? Or take it to Apple? I bought it at Best Buy and can still exchange it if need be. The only problem is that I cannot recreate the problem as it just happens randomly. Also I did not hit the power button or hold it down, nor was the laptop overheating at all. The only thing I was doing on the machine both times was internet browsing.
