I occasionally play on an 11" 2011 macbook air and it runs acceptably most of the time, though the framerate makes you sink like a rock when levitating. I don't like to charm on it since the trackpad and overall performance isn't suited to the super fast reaction times you might need to stay alive. EC or the Plane of Air corpse island fucks up the framerate and can cause hard crashes especially when I turn my character left or right, for whatever reason. It also drains the fuck out of the battery. I can only get about an hour and a half if I'm not plugged in.
I use wine to run it. There's a terrible youtube guide out there to installing and setting up. It takes some trial and error to get it working right. Let's see if I can find it and post back before my edit timer runs out.
