I doubt it. Even people with high-end systems are finding it is very intensive. Also, there are a lot of issues with the game right now on Windows. I'd never recommend buying a Mac for gaming.
Using an early 2008 MBP and it works on low-med. Getting 20-30 fps. Looks kinda like GTA SA on really high. Some minor problems, a few seconds slow downs here and there. Not a bad game.
