Easier to play on Mac, but keeps hanging for me

Played a couple of hours on my phone and decided to get it on Mac since the game supports iCloud saves. I find the control easier (after fairly short learning curve) on Mac but the game now freezes repeatedlly for me in Chapter 3 (Kirkwall), on a mid-2011 iMac running OS X 10.8.2, very frustrating for an otherwise enjoyable game.
