I want to play this game all the time but it freezes

I purchsed the version of XCOM for my ipad about a month ago. I loved it and had a lot of fun playing in it until I progressed to a point in the game where my 16gig iPad would freeze up. So I waited a while and finaly decided to purchse the game for my desktop computer thinking I would have better luck. I haven’t. I just started playing it and withing the first 45 minutes the game froze while I was trying to customize soldiers. I can’t believe how big of a sucker I am, to think that they created a mac version of this game that wasn’t buggy. Fool me once shame on you, fool my twice shame on me!
