Does someone know if I should need to format my HD before installing the latest build of 10.1?
I currently use the commercial (10.0+9.1) + updates since the 10.0.4.
I have stuff in Mail.app prefs + others. Will anything in /Users be modified by the Puma's installer? In other words, will the G24-build work as an Update, more than a First-time installer?
