I bought the macbook in summer 2009 right before the refresh, so i have the one without the glass trackpad, improved ram and hard drive. My macbook only has 2GB ram and 160GB of hard drive and it needs a serious upgrade if i want to continue editing HD video and working with adobe illustrator and whatnot. I hear stories of people upgrading their macbook and they won't boot up and stuff like that, i have no experience in upgrading computers. What's the best way to approach ram/hard drive upgrade on a macbook? Please and thank u.
