Hey Guys, I have a macbook that was the first aluminum macbook made. I have 2 GB of ram and would like to upgrade it. I don't know anything about it. How much can I upgrade to? Is it safe to put another memory in that isn't apple's? and when I do it, and click onthe apple icon and go to about this mac, will it still say 2 GB? or will it change and recognize it on its own? or do I have to change it? Sorry for all the questions. I'm new to all this upgrading stuff. Thanks in advance everyone!
