I've been using my MBP since I purchased it in Oct of 2006 (specs in sig). It's not as fast as it used to be and even after fixing permissions and running programs like OnyX it still slows up every now and then. I'm looking to do a clean install and start over. Any suggestions on the best way to do this? Losing my data is not an issue, I will back up what I need. As far as iTunes goes, how would you guys recommend backing it up? I can pull over the entire folder to my external HD, but will I have to re add them all back after the install?
