My problems are as follows: It seems that my Mac will no longer detect the iPod since configuring it to the PC. After playing around with it a bit, I was able to restore the iPod. It still doesn't seem to work properly. While my Mac will detect it now, it won't let me manually manage the songs, only preform complete updates. When I try to change the setting to manually managment, a notice pops up that I have to manually unmount the iPod disk image each time. What does that mean? iTunes also won't let me drag selected playlists to the iPod either. After these problems, I went back to the PC and tried plugging it in, to which I found a message that the iPod was no longer configured for PCs and my only option was to restore it entirely, again. I fear I'm faced with having to choose only one computer to use it with. Any comments would be greatly appreciated.
