When i first got my unibody 15", it was real fast. But now, after the installation of various software etc etc, things are slowing down. Launching an app from the dock is around 4 bounces, which i think is fairly long. And i get the beachball a fair bit now, not freezing, just taking its sweet time completing what ive asked it to do. Is there any clean up/speed up tips i can do? Please help me! I have done the following - Repaired permissions Deleted unwanted login items Anything else?
