Several days ago, I successfully reloaded my iPod Classic after I first installed Catalina on my MacBook Pro. But now, several days later, when I tried to update and sync again, this happened repeatedly: I plugged the iPod into the Mac, the Finder window sidebar recognized the iPod (under "Locations" and with the "Eject" delta to the right), and the iPod screen showed "Synchronizing" and the two arrows spinning slowly in the screen's yellow-orange circle. So far, so good. The Finder window continued to recognize the iPod, and clicking on the Finder window iPod link yielded the expected and appropriate boxes and screens, incl. "Music," so I checked the "Sync Music onto...iPod" box, checked the "Sync: entire music library" box below it, and finally clicked on the "Sync" button at the bottom right, which then went gray and stayed gray. The iPod screen continued to show "Synchronizing" (as above), but the Finder sidebar still had the iPod listed under "Locations" with only the original "Eject" delta and no spinning arrows that usually signify syncing. So: Was it syncing? If it was syncing, how would I have known when it was done? If it wasn't syncing, what should I do? I am concerned that "Restore" might very well "clean" the iPod but that reloading it, given this glitch, might not happen successfully and I would lose my iPod's entire (and substantal) library. One final note: after a while, I went back to the Finder window iPod link and, after clicking on it, the "Loading" page came up, and many, many, many minutes later, remained up with no sign of the "Music" or of any other box or page. I finally gave up and used "Force Eject." The good news is that the iPod tracklist remained intact as it had been after the initial reloading days ago, but no further updating took place. Any help anyone can provide would be greatly appreciated. Thanks.
