How to connect one Nano to 2 different iMacs on a network

Question

I have 2 separate iMacs (up & downstairs) & want to put songs I've downloaded onto the downstairs iTunes onto my Nano -- which I "registered" with the upstairs iMac, (that's where I recharge/update my iPod from). But the downstairs iTunes has all the great songs! How can I get them onto my Nano, has anyone else encountered this problem? I can share the libraries, but can't seem to get the downstairs files onto my iPod, and can't plug in my Nano downstairs: get an error message telling me it can only be associated/updated from one computer.?

Answer 1

If you want to connect and use an iPod on more than one computer or with more than one iTunes library you need to connect your iPod to your first computer and change the update preference in the iPod Summary tab to "Manually manage music and videos" and click Apply.

You can also use a keyboard command to prevent your iPod auto-syncing with iTunes. While connecting the iPod to the computer on a Mac hold down the Option and Command (⌥ and ⌘ Apple) keys. This will stop the iPod from auto-syncing with iTunes and it will appear in the source list. Wait until you are sure the iPod has mounted, and that it will not auto sync and then you can let the keys go. This may take between 20 to 30 seconds depending on your computer. You should then be able to change your settings: iTunes Keyboard Shortcuts for OSX
