I have a 15 inch macbook pro (mid 2009 1.8ghz core 2 duo) and I want to upgrade the memory. It currently has 4gb (2x2gb) and the maximum Apples says will work is 8gb. I am wondering if I could get away with 16gb (2x8gb). I know this is possible on certain other macbooks, I am just wondering if it will work on my model.
According EveryMac.com no Macbook Pro models build before 2010 had an actual maximum RAM of 16 GB. If your Macbook Pro is a 2009 year model, then your maximum actual RAM should be 8 GB.
