so today i went to frys to pick up some crucial ram on saleand decided to get cod4 just to play with it on my imac, so for some reason i put it in my black macbook 2.4 ghz 2gb ram, 250gb hd, and it ran! even tho it said graphics chip not supported, it lagged a bit at optimal settings but changed the settings and now it runs oh so smooth, also i need to install that ram on my macbook, ive tried and tried but screws ARE TOO TIGHT!!! rawr
