How to Eject an iPod
- 1). Open iTunes.
- 2). Click the iPod's name beneath "Devices."
- 3). Click on the upward facing arrow to the right of the battery icon next to the iPod's name. The iPod is "ejected" from iTunes. Leave the player plugged in if you want to keep charging the iPod. Otherwise, move to the next step.
- 4). Disconnect the iPod cord (or iPod if using an iPod Shuffle) from the computer.
