As I understand it, this is the best of both worlds; it installs a fresh copy of the OS then moves your settings into that install. Here are some general guidelines that I follow when installing OSX that at least minimize potential problems: - Run DiskWarrior or at least DIsk FIrst Aid prior to the install to clean up hard drive bits. - Use MacJanitor (free) or some similar app to clean up the Unix caches prior to install. - Repair Disk permissions (through Disk Utility) both before and after the install. - Of course, back up all important data. Another thing that is much more important with OSX than in previous Mac OS install is to READ the readme docs. These actually contain important information that may be specific to your hardware...OSX is less forgiving of seemingly minor issues. -mike
