So I just joined the community since I'm going to see about purchasing a MacBook Pro after an update coming in the very near future. I just wanted to know what specific RAM I can purchase (2 2GB Sticks for 4 GB) from what brand, what type, and where to buy. I don't mind online, but I highly encourage myself for local (I'll look up some stores around my area for good RAM). So the ultimate question is, what is the cheapest, most usable 2- 2GB sticks I can buy for an upcoming MacBook Pro? I have seen tutorials on how to add RAM to Pros on youtube, but am a bit skeptical about voiding my warranty. Does it void a warranty? Thanks for any help.
