To be honest I'm not sure. I use it only to do an occasional wired backup of my iPhone and iPad. Every time I use it it seems to have issues of some kind. IMO iTunes has always sucked and probably always will. So I avoid it like the plague except when I need to add files or do a backup. I will say, every time they do a major update they seem to change the user interface, and that makes me have to search for the features I need to use.
