You answered your own question. Your Mac is too old.

Alex, I'd like to buy a punctuation mark.

That's Apple for you. Unless you can somehow force an upgrade to a newer version of the macOS software, you can't do anything with your iPod in terms of using iTunes to manage your media. Without a compatible computer (Windows or Mac), you can only buy music through iTunes on your iPod or subscribe to Apple Music or other music streaming services (Pandora, Spotify, etc)
