I listen to iTunes on my older office Mac Pro every work day. I apparently reached a moment of truth about not updating the iTunes on it (runniing OS 10.11.6). It stopped running Internet Radio stations so I allowed it to update and that appeared to be that after a restart. Then two hours later it stopped working again and crashed out, not allowing iTunes to be restarted until it was done updating. Now it is done it has come back as iTunes 12.8.2.2 which I assume is the latest; haven't noticed anything not working but the last time I allowed it to update it decided I wasn't entitiled to some of my music but I seem to have gotten that all back!
