A) SUMMARY OF ISSUE

The djay Pro user interface freezes repeatedly while browsing a local Finder Folder library. Playback is generally unaffected, but the UI becomes unresponsive for several seconds, making the application difficult to use.

The issue persists after a clean reinstall and rebuilding the library from scratch.

B) DETAILED STEPS TO REPRODUCE

  1. Install djay Pro 5.6.7 from the Mac App Store.

  2. Add a local Finder Folder containing MP3 files.

  3. Browse the library normally.

  4. Scroll through tracks or navigate between folders.

  5. After a short period, the UI freezes for several seconds.

Additional information:

  • Library contains only ~30 local MP3 files.

  • Files are stored on the internal SSD.

  • No external drives are connected.

  • Library was rebuilt from scratch after reinstalling.

  • Issue occurs consistently.

C) EXPECTED RESULTS

Browsing the library should remain smooth and responsive regardless of the number of tracks.

D) ACTUAL RESULTS

The UI freezes repeatedly while browsing the Finder Folder library.

The application becomes temporarily unresponsive before recovering.

I collected two macOS sample reports during the freezes. Both show the main thread blocked inside the library management stack, including:

  • ARMediaLibrary

  • YapDatabase

  • SQLite

  • ALCFileSystemMediaObject::loadAttributes

This appears to indicate that the UI is blocking while accessing or indexing the local library.

I can provide both sample reports if they would help investigate the issue.

Important finding: the freezes only occur when the library is displayed in List View. If I switch the exact same library to Grid View, the freezes disappear.

Hi @jpdasilva, welcome to the Community! Sorry for the delayed reply. Thanks for the setup details the thorough report. Narrowing it down to List View is a really useful clue.

You’re already on the current build (djay Pro 5.6.7, released 7 July 2026), so there’s no newer version to try. I have some follow ups to help with the troubleshooting:

  1. Please upload both sample reports to your Google Drive/Dropbox, enable sharing permissions and share a link to the files here or in a DM to me.
  2. Did this same setup work correctly on an earlier djay Pro version, and if so which one?
  3. Does the freeze also occur when browsing My Collection or a streaming playlist in List View, or only the local folder source?
  4. Does it still happen after disabling all optional metadata columns in List View?
  5. Was track analysis running or pending when the freezes occurred?
  6. Does it happen immediately after launch, or only after the app has been open for a while?
  7. Does the freeze correlate with scroll position, with hovering over specific tracks, or with the preview player?
  8. Is the folder added under My Files > Add Folder, or dragged into My Collection? Does List View freeze in both, or only in the folder source?
  9. Is the folder inside Desktop or Documents (so it’s covered by iCloud Drive), or somewhere outside iCloud sync?

Thanks!

Hello! It’s been a week since my last reply. I’m going to consider this topic completed for now so I can focus on others. However, please feel free to respond and we can definitely revisit this. Thanks!

Hi Slak_Jaw,

Thanks for the follow-up. I checked the current setup and here are the details I can confirm:

  • djay Pro: 5.6.7 (66445)
  • macOS: 26.5.1
  • The app has been open for about 29 minutes when I captured the sample.
  • The local djay library is stored at:
    ~/Music/djay/djay Media Library.djayMediaLibrary/MediaLibrary.db
  • I do not see the library under Desktop/Documents or any CloudDocs/Mobile Documents path on this machine, so this does not look like an iCloud Drive-backed folder.

I also uploaded a fresh sample report here:
https://drive.google.com/file/d/1mTtYc1KxQPwziZWDkCaXDOa34ELxVNQK/view?usp=drivesdk

A few observations from the sample:

  • The main thread is mostly idle in AppKit event handling.
  • There is active work on the main queue involving YapDatabase / ADCDatabaseManager and SQLite reads against the MediaLibrary.db file.
  • That points more toward library/metadata work than an iCloud issue.

Answers to your questions:

  • Did this same setup work correctly on an earlier version? TBD
  • Does the freeze also occur when browsing My Collection or a streaming playlist in List View, or only the local folder source? TBD
  • Does it still happen after disabling all optional metadata columns in List View? TBD
  • Was track analysis running or pending when the freezes occurred? TBD
  • Does it happen immediately after launch, or only after the app has been open for a while? It can happen after the app has been open for a while.
  • Does the freeze correlate with scroll position, hovering over specific tracks, or the preview player? TBD
  • Is the folder added under My Files > Add Folder, or dragged into My Collection? TBD
  • Is the folder inside Desktop or Documents, or somewhere outside iCloud sync? Outside iCloud sync, in ~/Music/djay.

Best,
Jp

Hi @jpdasilva, sorry for the delayed reply - I’ve been on holidays.

  1. Can you please enable sharing permissions for your linked Google Drive report?
  2. Please confirm whether either sample was captured during a live freeze.
  3. If not, please provide a sample or spindump captured with explicit confirmation that the UI was frozen at capture time.
  4. Capture a screen recording showing the freeze in List View and then the same library in Grid View not freezing, within one session.
  5. Take a screenshot of the List View browser showing enabled metadata columns and active sort column.
  6. Confirm your exact Mac model, chip, and RAM.

Thanks!
