Applogies for the newbie question. I notice that my Macbook is getting slow again. The fan starts for nothing even in really cool temperatures and on average it's just much slower than before. I usually fix this by re-installing everything, but this time I have so many things installed and set-up so I wonder if there's maybe another way to regain the same speed you get after a new fresh install. Like a safe soft that would clean-up your drive and de-fragment it (don't know if you're still supposed to care about this these days). My internal drive is 700GB. Macbook is a 2GHz Intel 2 with 4Go RAM - OS 10.6. Thanks a lot for any help.
