My 15" Macbook Pro (in my sig) seems to be getting slower (as in startup and response time)and I use cocktail to clean things up but it doesn't seem to help. I was thinking about doing a fresh snow leopard install but here is the question. If I do a clean install then restore from my time machine back up, will it just bring it back to the state it's currently in? Or is there another option I should try first?
