I have a refurbished black macbook. I bought it late 2007, so i'm guessing it's a mid-2007. I searched macrumors and other sites but i can't get a definitive answer. I know I can put 4gbs of RAM into my mac. But will it be able to actually SEE AND USE all 4gbs? I have to 1gb chips in it right now. And if I upgrade, will it make games like Spore or World of Warcraft run smoother? UPDATE: I do have the mid 2007 with the GMA 950. So does anyone know a way I might be able to force the mac to use all 4 gbs. I know that might not be a good idea. But please post a tutorial if you know how.
