Some quick questions, my iMac has become incredibly slow over the years and I was planning on performing a clean install on the machine. I have a time machine backup which I would transfer my files back onto my Mac from. I have a few questions about the process: 1. Will this give a noticeable speed boost to my iMac? 2. Will Time Machine keep a copy of my emails from Entourage (part of Office 06) 3. Will licensed software like pages, microsoft word, etc. have to be reinstalled with proper license codes? Hope some people can provide answers to this. Thanks!
