Apple Music crashing after iMac Sequoia OS 15 update

Hi All,

I installed the Sequoia OS 15 update on my M3 iMac, and now Apple Music crashes after about 15 minutes of use, when I try to drag a song into another playlist. Is this a known bug, and if so, when is the new update coming out to fix it?

Thanks,

Steven

This exact situation is affecting me as well. Music crashes every time I drag a track to another position. I hope an Apple solution can move this narrative forward, sooner than later.

Not exact same problem but it is after downloading Sequoia in Music, but I had over 1000 songs disappear again from the library after the update. Also, I preordered an album and got notice it had dropped and was available, but not showing in my library, and tried to download it and said it was being updated. I have not been billed for it, but will not let me access it without buying it again.

Also experiencing this since I updated to Sequoia 15.2, and finally identified the conditions under which this happens:


If you drag and drop a song in a playlist, and that playlist is set to view "as Playlist" in the "View" settings, and the song you try to drag does not have an album title, then Apple Music main thread crashes with a swift::swift_dynamicCastFailure.


If you try to drag the same song with the "View" set to "as Songs", or any other view besides "as Playlist", then there is no crash.


If you edit the metadata of the song to have an album title, and then allow the playlist UI to refresh by clicking on the playlist in the sidebar again, and then attempt to drag the song, then the app will not crash.


In contrast, if you edit a song without an album title to have an album title, save, but do not allow the playlist UI to refresh (so that the UI is still not showing an album title), and then try drag the song, the app will crash.


This is reproducible every time.


This is a SwiftUI bug and has nothing to do with the specific of the song, or even the underlying metadata. The temporary workaround is to view your playlists "as Songs".

Is your music on an external drive?


There seems to be a problem with indexing a particular drive. This is noted by

  • spotlightknowledged - High CPU Use - Responsible for indexing files on your drives
  • media-indexer - High CPU Use - Specifically for indexing media files like Music.
  • suggestd - High CPU Use - Processes the info gained from the indexed files


I would start by eliminating the Hub and all external devices to see if it resolves the problems, then start adding drives directly connected to the Mac. This is one source of a Kernel Panic problems and why it says it may be Hardware related. See if it makes a difference when you add the Hub to the mix. Many times the Hub has been identified as the source of the problem. I assume your Hub is self powered, as there may not be enough power provided by USB. If you are able to identify an external device causing the problem, then steps may be taken to resolve it.


I would also experiment with Rebuilding the Spotlight Index and excluding some of the drives to see if there is a particular drive that is not allowing Spotlight to successfully index the files. It will take some time to let Spotlight finish the index.

As for software, you look pretty good. The one thing that stands out related to the indexing of the files is the Adobe Content Synchronizer Finder Extension. Not sure if you are actively using Adobe Acrobat or if it was installed for another reason. The one kernel panic started on 9/18 when Adobe Acrobat was installed for the second time. I have no specific information about a compatibility problem with Sequoia so I can't call out that specific app, but if you want to test with Adobe installed start by using the uninstaller, then make sure these files/folder have also been removed:

  • Applications/Utilities/Adobe Sync
  • /Library/LaunchDaemons/com.adobe.ARMDC.Communicator.plist
  • /Library/LaunchDaemons/com.adobe.ARMDC.SMJobBlessHelper.plist
  • /Library/LaunchDaemons/com.adobe.acc.installer.v2.plist
  • /Library/LaunchAgents/com.adobe.ARMDCHelper.cc24aef4a1b90ed56a725c38014c95072f92651fb65e1bf9c8e43c37a23d420d.plist
  • /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist
  • /Library/LaunchAgents/com.adobe.ccxprocess.plist


All those files are running on startup to support Adobe. You can find these files by going to Finder > Go > Go to Folder, then enter the first part of the location like /Library/LaunchDaemons or /Library/LaunchAgents, and you will see those files there.

I have been experiencing this issue since upgrading to Sequoia. I'm now on Sequoia 15.3 and it is still an issue. I've noticed that it affects songs that were not purchased through the iTunes store more often than songs that were. The issue is only observed when trying to rearrange songs in one large, frequently used playlist in my library with a click and drag. I can move purchased music *sometimes* but can not move imported mp3 files at all. It always results in a crash and close. Possibly an indexing issue?

I can confirm that for me on Sequoia, that I can move tracks across many different playlists, so it would not be a system wide bug that affects every user. There may be a third party app that is interfering with the normal operation of the OS and is installed to launch on startup. These could be a syncing service such as OneDrive or DropBox that is corrupting the music file when it is trying to sync or CleanMyMac which is known to crash apps. For more details on what is installed on your computer that could be causing the problem, post the free EtreCheck report. It contains no personal information, but will show system processes launching on startup and give more details about crash reports that may identify the problem.

iMac 5K 27 inch 2019 3.7 GHz 6-Core Intel Core i5 64 GB 2667 MHz DDR4 memory. Mouse is Razer Deathadder Elite and hardwired to iMac. Apple keyboard also hardwired. I upgraded to Sequoia 15.1 everything ran fine for a few days. Everything still runs fine except the Music app it does not respond to right click on mouse, I get no dropdown. It does not respond to key commands i.e. command i, I get the error bleep. I can play music, but only one song at a time from the playlist. I can select all from keyboard in playlist, but can go no further. These commands on the keyboard and the right click on the mouse work fine in every other aspect on my iMac except in the Music app.

Tried dropdown at top right of playlist see image below.

I have restarted both my iMac several times as well as the Music app several times. I checked that the Music app recognized this iMac.

Everything you describe is reproducible on my end.

The two fixes you mentioned work. I can view the playlist "as Songs" OR add an album title to a song without one when viewed "as Playlist".


In my original post, I wondered why this only happens to one large frequently used playlist and I observed a detail. Create a new playlist with File -> new -> playlist and name it. Put a couple songs in it and the playlist UI will have a row for Song, Artist, Album, and Time at the top.



I can move songs around in ANY playlist, with or without an album title in the meta data, that has these four columns. My playlist in question does not have the "Album" column.



I can only move songs around in this playlist that have an album title OR I have to view "as Songs". To get around this. I created a new playlist and added all the songs to it. No good. I've identified three songs that, when added to this list, remove the "Album" column from this new playlist. When I add any of these three songs to another playlist, they do not have any effect on the "Album" column. My new playlist is 600 minus those 3 songs and works as intended. Yes this took a while as I transferred them in small groups. Still digging but this seems like a Swift UI issue like you mentioned. The three songs in question all have title, artist and album titles.

My music is also on an external My Passport 4T drive which is connected to ACASIS 7 Ports 36W USB 3.0 Data Hub with individual On/Off switches and a power adapter. When playing music I only have the one port which contains the drive that holds my music (MP3s) active. There’s 355.71GB of music files within that drive, I don’t imagine there’s a limit(?)

I’ve swapped ports on the hub with another same make drive and though it does not contain MP3 music files ( they’re MP4 movie files) nor is it linked to the Music app the files within show a dropdown menu when I right click on them and the files respond to the commands. I’ve removed the drive from the hub and connected directly to my iMac in a different port and still the same result.
