So I'm sure that some of you have Dell DJ Ditty MP3 players by now. Mine was given to me, but I'd like to make it useful. The problem is that according to Dell, it doesn't work with OS X. At all. Actually, I think it works easier with OS X than Windoze, and here's how:
Plug it into a USB port (must be powered). Look for the external drive that mounts in the Finder -- mine was called 'Untitled.' Put your music files here: Untitled/Music/Artist/Album/, then eject the disk. (Replace Artist and Album with the proper values for the music you're transferring, of course.)
Make sure you use MP3s. I thought this didn't work at first, because I used AAC files, which the Dell does not support.
