Hey People. I just bought a new 2.4 Aluminum MacBook with 2GB of RAM However the guy who bought if for me only got 2GB of RAM when I needed 4GB. What are my options for upgrading? Is it possible to get more RAM from Apple? Do I have to rely on 3rd Party RAM like from OWC or someone else? Who makes the most reliable RAM for my system? Should I even consider these options or will I screw up my new MacBook? Please help if you can. Thanks people.
