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!
