Why doesn't syncing of music from Mac to iPhone maintain the hierarchy of playlists?

I have a well-formed collection of music on my iMac, where I can access any playlist and play the music. I have connected the iMac to my iPhone 17 Pro using a USB cable, and performed a sync so that the Mac's music is copied to the iPhone. I can see the copied music by looking at the contents of the iPhone using the Mac - all the playlists I chose are there BUT when I start up the Music app on my iPhone, a lot of the playlists are missing! I find that they are there, shown under "recently added", but not in the right places, so to speak.

As an example, I have playlists in a hierarchy of folders, e.g. Beethoven/Piano Concertos/Beethoven pno Concerto No 5 "Emperor". This all looks right on the Mac, but although this structure exists on the iPhone, it doesn't include any new playlists - so I just have to search for the playlist I want by looking through the Recently Added collection.

How can I ensure that the folder structure used on the Mac gets transferred to the iPhone?

This is a long-standing limitation in how iOS handles deep playlist folder hierarchies during a local USB sync. While the Mac can support multiple levels of folders, iOS often flattens these or only displays the bottom-level playlists in "Recently Added". Here is how to ensure your hierarchy transfers correctly:

1. Use "Sync Library" (iCloud Music Library) — This is the most reliable way to maintain folder structures. If you have Apple Music or iTunes Match, enable "Sync Library" on both the Mac and iPhone. Changes to folder structures on the Mac will mirror perfectly to the iPhone over the air.

2. Simplify the hierarchy for local sync — If you must sync via USB, try reducing the folder depth to a single level (e.g., Folder > Playlist). iOS struggles with 3+ levels of nesting (Artist > Album Category > Specific Playlist) during a physical sync.

3. Reset the Music Sync — Sometimes the sync database on the iPhone gets "stuck" with an old folder manifest. On your Mac, uncheck "Sync Music" in Finder for your iPhone, sync it so all music is removed, then re-check it and sync again. This forces iOS to rebuild the folder structure from scratch.

4. Check for nested empty folders — Ensure every folder in your hierarchy contains at least one playlist that has songs in it. iOS often ignores folders that it perceives as "empty" or purely structural during a USB sync.

5. Update macOS and iOS — Ensure your Mac is on the latest macOS and your iPhone 17 Pro is on the latest iOS 26.x. Apple has made incremental improvements to the Finder-based sync engine in recent updates.

6. Use a "Smart Playlist" workaround — Create a Smart Playlist on your Mac that gathers all songs from a specific folder. This single playlist will always sync correctly, even if the sub-folders don't appear in the right hierarchy.

Hope this helps get your classical collection organized on your iPhone!

Thanks v1v3km for you suggestions. While I don't understand everything you say, particularly Item 1 (where would I find "Sync Library" related to iCloud?) nor why you say "if you must sync via USB" when I don't know that there's another way, nevertheless I am very grateful for your reply.

So far I have tried your Item 3 without reference to your other points. I got the iPhone music to delete, as you say; I then restored the music from the Mac. This took a long time, as expected, and from the display during the transfer process I thought everything was going across, but on opening the Music app on the iPhone, all my newer playlists were still absent! I tried restarting the phone, but still no joy. The 'Recently Added' section doesn't include all my playlists (for example the Beethoven Piano Concerto I mentioned before), and the section has a lot of displays of album covers which I don't want, especially as several of the original albums contain pieces that I have not included in my new playlists. So things are not going well.

I should have said that everything is up to date on both devices (your item 5).

I'm reluctant to alter my basic structure or adopt the "Smart Playlist" solution.

Have you any other suggestions? Maybe I should call Apple.
