Hi guys, I have a MacBook Pro that came with Tiger, but I upgraded to Leopard when it came out (the default upgrade process as far as I remember). To get rid of the cruft that's built up, I'm thinking about starting a new when SL is released, and wiping over everything, then restoring /Users from a backup (I use Superduper! and Time Machine). Is this a good idea? Or is it best to let the installer do its thing, and really I won't see any difference by using the easy, standard upgrade process? Thanks guys.
You might like the "Archive and Install" option (which I think is supposed to be the default one now). Basically it moves all user data into one folder and erases everything else on the Mac OS X partition. That way, you get a clean install but you can still access your Documents etc. Of course you should still make sure there's a backup, just in case it goes wrong.
