I'm thinking of upgrading to Mountain Lion and when I do I'd like to do a fresh install. This would be possible? Also, what is the best way to prepare iTunes for the transfer. There are two user accounts on my laptop which is on Lion now. Can I maintain the same settings, music, podcasts, etc? I understand that I would have to reimport the music again, but I'm worried about losing applications and settings in iTunes and have to redownload things again. Thanks in advance.
