Old iPod won't show up in iTunes

Hi Sophie..

"it won't show up in iTunes" ..

Your profile suggests your Mac is running v10.10.3. If that is the case, updating your OS X software and iTunes may help.

The OS X 10.10.5 and iTunes 12.3.3 updates are available.

Disconnect the iPod prior to installing the updates.

Click your Apple  top left in your screen.

From the drop down menu click About this Mac

Make sure the Overview tab is selected then click Software Update.

Your Mac may restart several times during the update process. That’s ok.

Then reconnect your iPod and see if iTunes recognizes it.

OS X 10.11.4 is currently the latest version. My old monochrome-screen iPods (including an iPod mini) work fine with the latest OS X and iTunes, on my Mac mini.

In the latest iTunes, iPods appear as a small device button on the horizontal bar that goes across the iTunes window. Here's a screenshot of my iTunes window (upper left corner) showing an iPod's device button (circled in red).

You don't see the device button in iTunes when you connect the iPod? If you do, click the device button to show the iPod's settings screen.

If you don't see the device button, watch the iPod's screen when you connect it. Does it initially say "Do no disconnect" or give other indication that there is a connection? Or does it only show the battery charging symbol?
