It's a amazing game, with a wonderfull story. It plays fine on my Macbook 15" from late 2011 with 512mb vram. The only problem I've had is, that when i open the game sometimes the keyboard doesn't respond, but I found a fix for this, it works for me. Plug out you external mouse before you go into game, when the press enter button pop us, press enter on keyboard, then plug the mouse back in. That's it :) great game!
