In the past months my Macbook (specs below) has become extremely sluggish and slow to the point of it being a real pain to use for the most basic tasks. I want to completely wipe the hard drive and re-install OS X. Can somebody post a tutorial for the fastest and easiest way to do this. The only things I am bothered about keeping are my huge iTunes library, around 500 photos and some work documents I need and a large collection of applications that I will need in the future. I have a USB external HDD which I can use to store things on. My Macbook's specs... Black Macbook running Leopard 10.5.8 2 GHz Intel Core 2 Duo 2GB RAM 120 GB HDD I don't want to run any 'clean-up' or 'maintenance' apps, I have tried this over and over to no avail. Wiping and re-installing is the only thing I will try. Please can somebody help me out, my mac is almost impossible to use.
