My MacBook Pro has been slowed down a lot lately. I do everything I can to keep it clean and unclogged, repair permissions, run maintenance scripts, the works, but it just runs really slowly. It takes a lot longer to boot than my mom's MacBook which she's had longer! According to every test, my hard drive is fine (and plus, via BootCamp, Windows runs pretty smoothly). It's quite annoying when I have to wait 5 minutes to load up OS X. It also takes a while for programs to load up (longer than usual). What can I do to speed things up? Just to let you know, everything in Windows is really snappy. There's definitely something wrong here.
