Guys - I've had the macbook since it came out and recently it's really started to slow right down. I have photoshop/lightroom/iphotos/itunes installed which are the biggest apps, but at the moment i'm not even using anything except itunes and photo's. I'm getting the beachball on startup before anything has even opened. the only other thing i can think of is Norton is installed (after i had my credit card cloned, i wasn't sure where it happened) and is slowing it down. I'm going to do a fresh install tonight but wondered if anyone else is encountering it? I'm considering selling it and buying a RMBP instead. Thoughts?
