rashes a lot on my retina macbook

This game freezes and crshes the computer a lot. It gets stuck and then cannot open or close anything else. I have 16gb of RAM and 1GB of video memory, so it cant be the computer specs, or the lack of processing power, it has to be abug in the program itself. Nice game if it would not crash every time.
