I own a pre June Macbook pro 2.53Mhz. I wanted to see how much Ram i could upgrade to so i went to apples Upgrade kit pages for macbook pros before June http://store.apple.com/uk/memoryfamily/ME_MBP_AL_G1 The pre June 2.53mhz Macbook pro is not listed amongst these instead it is listed amongst the current generation of post june Macbook Pros with the option to upgrade to 8GB http://store.apple.com/uk/memoryfamily/ME_MBP I have talked about this with one or two friends and they have told me that a MONTH AGO the same upgrade pages USED to show the two MBP 2.53mhz seperately and say the pre june MBP 2.53ghz could only have an option to upgrade to 6GB. Now the apple website suggests any macbook pro 2.53mhz can upgrade to 8GB. Is this a mistake by apple or have they done something to now allow 8GB in both pre and post June MBP 2.53ghz? I dont want to buy ram from apple, im just trying to find out if Apples RAM upgrade pages are correct in leading people to think ANY macbook pro 5.23mhz can install 8GB.
