Well, the support link says iPod Touch, that’s not all iPods. I was thinking about older models to be honest.

I’ve been told in another comment that they still sync, via Finder. I have had issues with that, but it’s probably okay from what other comments say.

I’ve done an online search and I see other people that have had technical issues syncing with Finder. I guess it depends on the macOS version, iPod model… who knows.

I’ve used Clementine but found it to be clunky and unreliable. Again, just my personal experience with it.
