Seriously? No uninstall program for LR 5 when you upgrade to LR 6 CC on Mac OS? That's a bad oversight. You really want Mac users mucking around in their library files deleting stuff and hoping for the best? I noticed there was an uninstall for CC now, but come on. This is basic stuff Adobe. Maybe at least some directions on the new install so you know what to remove without having to google a solution.
