The iPod aren’t supported anymore, they require iTunes which is no longer available on macOS.
Absolutely false. Why would you even post that?
iPods are 100% supported on macOS, and its Music program.
I have five Shuffles, and an iPod Video, and I use at least one of them almost every day, and sync them with my Macs monthly.
It’s true that after iTunes ceased to exist it was then possible to sync them with the Music app and Finder, I was wrong to say that. I meant to say that Apple no longer offers support for the device.
I have had issues syncing with Finder on a particular model. I assumed these models no longer worked with the OS. Happy to hear that they do. Maybe it was the OS version, or the model. I should try again.
