Before you can copy music from your iPod to your Mac, you must authorize iTunes on your Mac with the same account that was used to purchase the music.
If your Mac is already authorized, you can skip this step and go on to the next one.
Authorize iTunes
- Launch iTunes on the destination Mac.
- From the Store menu, select 'Authorize Computer.'
- Enter your Apple ID and Password.
- Click the 'Authorize' button.
