OK so I'm one of the people who got the 2.4GHz Unibody MPB when they were released. Now to my knowledge the 2.4 can have 6GB of RAM and run well but 8GB causes problems (plz say if u have successfully got 8GB to work). Now Apple have 8GB kits for the higher end models, though I remember some saying all but the 17" has problems running 8GB. What I want to know is (a) do the different models have different chipsets? and (b) if no will Snow Leopard allow the 2.4 mbp run 8GB with no problems (obviously we won't know exactly cause SL is not out just yet but then if my other question is true then an answer might be clear). Also nVidia state the chipset can have 8GB. Could a firmware issue be the cause and is there any chance apple could release an update that address the issue?
