Upgrading RAM of a MacBook Is it possible to upgrade memory to 8 GB my model of MacBook? The manual says no, but on the web some people have made some videos about the upgrade. I don't know if any of them are fake.
I found this site:

Other World Computing RAM upgrade for MacBook 6,1

It seems it's possible to upgrade.
