Since I'm new to Apple and Mac -- yes, unfortunately used to the Windows way of things -- I have a question before I install my new copy of iLife '09. My Mac Pro arrived a few days ago (this past Friday afternoon) and I haven't downloaded or have any files added into what would be iLife '08 (iPhoto 08, iMovie 08, GarageBand 08, and iWeb 08) so I have nothing I need to backup. So, do I need to individually delete (i.e. drag and drop into trash) all four programs (found via Finder) before installing iLife 09, or will iLife 09 over write the older "08" programs? Thanks!
