I'm having difficulty with these instructions. MacOS Mojave, iOS 13. Trying to use the iTunes sync to transfer music to my iphone. I don't see the option to Sync All Music; my only option is Sync Voice Memos. My phone doesn't appear in Finder either.
You have iCloud Music Library turned on. You cannot sync directly with iTunes when that option is turned on.
iCloud Music Library negates the need to sync your music directly since it uploads anything on your Mac to iCloud and lets you access it from your other devices directly. This is a feature of your Apple Music or iTunes Match subscription.
If you want to sync instead of using iCloud Music Library, then turn it off: Turn on Sync Library with Apple Music - Apple Support
Thank you! That worked like a charm. I had indeed canceled my iTunes Match subscription and wondered if that had something to do with why half of my music suddenly vanished from my phone. All better now!
You're welcome.
