Hi. I am thinking of getting a developer license (or whatever they're called ), not just for Lion preview but I actually will develop apps! (Lol) One thing I'm not sure of though - if I do get Lion I will want to install it on a partition of my internal HD, not an external one. However, in Disk Utility all my partition options are greyed out. Why? (Screenie below) http://i53.tinypic.com/qs5mpk.png Is it because I have Boot Camp as well as my Mac HD? Would this cause any trouble? Many thanks.
