Error occurs when trying to sync Apple Music library between iPhone and Mac

The weird thing is that in my case that link only shows me roughly 20% of my cloud library. So, on my Mac no cloud library at all, on my iPhone a 100% of the cloud library, and online cloud library ~20%. Bonkers.

I'm having this issue on the latest version of iTunes & Apple Music on Windows 11. First occurred in iTunes, so I signed out, de-authorised, uninstalled completely and reinstalled. Didn't fix. Tried same in Apple Music Preview.

Have cancelled my subscription until this is fixed - Literally no use for me because music doesn't play at all, keeps asking me to sign in again because 'session expired'. Web version works, but is very inconvenient to use compared to app.

Also, turning off iCloud library still doesn't allow me to play Apple Music content. It just tells me 'An error occurred'. So issue isn't just with iCloud Library Sync.

I'm having the same problem and none of the methods mentioned have helped me resolve it.

Also, I add an album to my library in the Music app on my iPhone, but it doesn't show up in My Library on Apple Music on the web.

I also can't synchronize the Apple music library on all devices, iPhone 15 Pro Max, iPad Pro 2 and 3 Macs Apple Silicon, error 18004 on Mac, contacted support for 3 days in a row without any result, I should call back but I give up.

The only device it seems to work on is the Apple TV, so the library seems intact.

I wonder how it is possible that a company like Apple can create difficulties for its customers, who pay the subscription, on a function that has worked very well for years.

How is it possible that with each update they add almost useless things and manage to make basic things stop working.

I'm very disappointed, on a software level there are too many problems, ios, macos and all the others are full of bugs.

Hi there, seems like it is fixed on my side although some of the more recent songs are still greyed, I got back all of my library and the playback works on my iPhone.

Need to check the app on W11 tho.

Keep faith brothers.

I have been trying to sync my iPhone 13 to my PowerMac for over a month now. I’m syncing the music on my phone to iTunes. At the third level when it is preparing to sync music, it just spins. I’ve restarted both the computer and the phone. It will sync pictures, just not the music. The phone seems to work fine otherwise. I almost went in and bought a new phone. A new iOS update should be coming in two weeks, so I’ll wait for it. I don’t know if this is a phone error or a computer error though. Help!

Hey Guys, over the span of the last few days I´ve had the same issues. Always got the error 18004. It seems like Apple fixed that Problem. My whole library just reappeared and everything works just fine. Hoping your problems will be fixed aswell.

Can confirm that everything is working again for me too.

Now downloading my entire Apple Music library to a dedicated Mac Mini. So that I always have an offline "backup" of all my music and playlists if an outage like this ever happens again.

I'm sick of this. I battled with this error for the last ted days. Apple support got logged me out, erasing all my wi-fi password. I'm paying for an Apple One month plan. This is SUPER annoying.

I have an appointment with a a Genius on a store. Will keep you posted if he came up with a solution.

Ask then for a few months free. They offered me 5 months and I didn't even have to ask them, however , I had already mentioned that I had spent 11 hours on the phone to Apple support

I have the same - very annoying - problem since two weeks, but I'm happy to see that I'm not the only one. I don't have to doubt myself, it is clearly an 'Apple bug'.

At a certain point only the web version of Apple Music showed the right playlists and my compleet music library.

At this moment some devices (iPhone, Macbook) are synchronized correctly, but not all. My iMac for instance still doesn't synchronize.

It seems like this error was riased by thousands of users and nothing happened so far, not even a official update from Apple.

What can we do besides shifting Music for Spotify? I will have to do that if this is not solved quickly.

THANK YOU @nabstar! This worked for me too. My Mac hasn’t been syncing music for weeks.

I did the various points individually but not all together. Perhaps this was necessary in combination to release the lock.

I don't know if it makes a difference, but in the last step I first logged into Music and then into iCloud services in system settings.

Hope this helps others as well!

I have this problem, too. No amount of troubleshooting provided by Apple solves it. Brand new MacBook Air M1 won't sync.
