Hello, I recently upgraded my MacBook Pro 13" 2.14ghZ (2010) to 8GB of Ram from 4, and it was just overheating. All I was doing was watching a youtube video. Before I took the picture I quite a safari process which was using almost all of the available free memory. Is this right? I only had 4gb a week ago and I've been able to have pages, preview, microsoft word, safari, illustrator AND photoshop open and then it starts getting laggy, but I don't even have photoshop open and it was using pretty much all the 8GB. Anything you can suggest? Thanks!
