A friend uses an old iMac DV400 just to store music in iTunes (the only thing she uses a computer for at home) but her iPods haven't been mounting on the desktop. But, I can connect with either FireWire or USB (4G iPod color) or USB (Product Red Nano) and they do show up under Disk Utility. I haven't been able to mount an external hard drive or DVD writer via FireWire, either, so I figured the ports were bad. But when the iPods showed up under Disk Utility, that had me stumped. She has purchased music on the internal drive she wants to move to her iPods but the lack of mounting is starting to piss her off. Oh, and she's running the last update of Jaguar and her iTunes is up-to-date for that version as well. It worked in the past with that set up so not sure what's going on now. Any ideas?
