I have a 17" flat screen iMac and a dual usb 500 mHz iBook. I mainly use my iMac for listening to music. But I use my iBook to run virtual PC and run kazaa. So I want to put some of the music from my iBook onto my iPod. Everytime I plug my iPod into my iBook it doesn't recognize it. It NEVER shows up in iTunes or on the desktop or anything. When I plug it into my iMac it works just fine. Any thoughts?
