I know most people know the Macbook is not a true gaming machine due to the lack of a separate video card, however I thought I would still try the Bioshock demo to see if it would run at the lowest settings. I really should have known this, but the demo wouldn't even run. I kept getting a microsoft error while trying to start the demo using a black MacBook with 2.16 ghz and 2gb of ram. I hope this helps someone else thinking about testing the demo on their MacBook...it just won't work.
