I am about to install OSX Mavericks in an iMac I have. I would love to make a clean install (creating the bootable USB with that complex procedure).
I was thinking about copying folder by folder but thinking about iTunes, iMovie and iPhoto makes things more complicate as they are stored in the
library folder and it can carry more than one problem I guess.
I was wondering if that "clean" install will again become "dirty" if I restore everything with the copy I have in TimeMachine.
Would that also transfer preferences and things which could interfere with the new installation?
