Hi, I have a fourth generation iPod Photo (30 gig) that was originally formatted for windows around a year and a half ago, before I owned a Mac. Now that I have a Mac, I always sync my iPod's music with the iTunes library on my Mac. Whenever I plug it in, under summary it says it is formatted for windows. There are no compatibally issues, but I was just wondering what it takes to make it say it is formatted for Mac. Thanks in advance.
