I have a MacBook pro (mid-2006 version) with a 2.33GHz processor. I currently have 3GB RAM installed and would like to have 4GB as I use Photoshop and FinalCut Pro heavily. When I bought the computer, 3GB was the max because of a limitation of Inte's chipset. I was wondering if one of the more recent firmware upgrades has changed this and now allows for 4GB RAM.
