I have this strange problem. Yes I know I'm using beta software but still... I have one MBP and Mac Pro. MBP crashes often when I'm using playground (it also seems to use a lot of CPU resources) while Mac Pro seems to have no trouble and hasn't crashed. What could I look into? P.S. it's my first time using Xcode but I've dabbled with UI builder in Xcode 5. I also don't use any 3rd party plugins.
