My 2 year old MBP running OSX has got more sluggish. The little multicolored spinning timer wheel keeps appearing a lot more now, and I hate it! When my old PC used to do this delayed reaction thing, I could go into the running applications and do a general de-clutter of things including the registry. As I am only a mac novice, I write to ask if there is a way to (safely) de-clutter and check the overall health of this loaded MBP and have things fast and punchy again like when I bought it? Oh, and something else on this theme of speed: If there is no/little improvement through the answers I get to my first question, when I install Snow Leopard do you think it will speed things and take me back to lighting speed? Thanks for any help offered.
