MacBook slowing down? Try Safe Boot
I just posted this to another thread but I think it bears repeating here:
I've had a MacBook for about 13 months. A few months ago (can't remember exactly when) it seemed to be running slower than it used to. I use it to run only really standard stuff: Microsoft Office, Mail, Safari, etc. No Photoshop or After Effects and the like. I was pretty sure that the slowdown was caused by upgrading to 10.4.9 or 10.4.10. I tried alot of recommended "fixes." Onyx, Cocktail, Disk Warrior, resetting PRAM and more. All of which are useful, don't get me wrong, but they didn't deal with the slowdown issue. I did one more Google search this morning under "macbook running slow". I came across a post on Macenstein that I hadn't seen before. The recommendation: SAFE BOOT! Doh! Forgot about that one. Start up your Mac while holding down the Shift key. Believe it or not, that seems to have done the trick. It's probably one of those things that should be tried for any system-wide sort of ailment.
