iPod touch doesn't sync
My iPod Touch (model MC011LL, version 5.1.1 (9B206)) won't sync with Music. (Late 2014 Mini, OS 12.7.6). It does not appear on the desktop; Music shows it in the left-side menu but the main screen in Music endlessly shows "loading". Disk Utility also does not show it. Any ideas, please?
Mac mini, macOS 12.7
