When Maverick's comes out, I plan to install it as a new OS. Mainly because my MBP came with Snow Leopard, and I've just 'upgraded' to Mountain Lion so far and there's a lot of things in downloads etc I don't really need. When it installs, is it just a matter of putting my external hard drive that does the Time Machine backups in and dragging the items I want over? I'm also curious about how Dropbox would work - Can I move items from my backup Dropbox folder, so it doesn't have to download 2GB of files on my Dropbox account? Thanks.
