Hi @Turf_Daz, can you please provide complete details for your setup? Device Model (ex. 2020 iPad Air 4th Gen): Version of operating system (ex. iOS 17.3.1): Version of djay (ex. 5.1.3): Hardware/controllers used (ex. Reloop Ready): Hardware Firmware Version: 1. Please also provide the exact steps in your workflow. . 2. What are the expected results? 3. What are the actual results? 4. A short screen recording would be really helpful in illustrating your workflow and the resulting issue. 5. The more details you can provide the better I’ll be able to help you. Thanks! ---

Thanks for the additional info @Turf_Daz 1. So you were running djay 5.6.5 and everything was fine? 2. This started after updating to djay 5.6.6 that was released about a week ago? 3. Are you running the 2.01 REV7 firmware from AlphaTheta ([DDJ-REV7 Firmware for Mac - AlphaTheta Help Center](https://support.alphatheta.com/en-US/articles/5321811361177?product=4416585726873))? 4. Did you do anything else on your Mac other than update from djay 5.6.5 to 5.6.6 (ex. macOS update, TimeMachine recovery, new software installation, etc.)? 5. What source(s) are you using for your tracks (ex. Local Music, My Files, USB Library, External Apps)? 6. Are you also using Apple Music Streaming? 7. What is your exact workflow for adding tracks to djay? 8. Are your songs stored on your Mac internal drive or on an external? 9. Have you recently moved the files on your Mac or renamed anything? ---

1. Yes 2. Yes 3. yes 4. I clicked to preview a track inside DJ pro library thats the little play button beside the track name in the library when I noticed tracks missing from that time moving forward so might of had something to do with a bug from clicking on the track library preview button 5. My library is on my 2tb MacBook Pro built in hard drive 6. No I don’t use apple streaming 7. I put my tracks in one folder in my documents then drag them across to the Dj Pro crates 8. internal drive 9. no ---

Thanks for linking these issues @Armigo. I think you’re potentially on to something here. @Turf_Daz, can you please try rolling back to macOS 15.7.1 or upgrading to Tahoe and retesting? Thanks! ---

Hi @Turf_Daz, I spoke with our engineers about this. If you use My Collection can you please try reimporting all your music again via dragging the folder/files from Finder and dropping them into the My Collection Music playlist? This might help as it will recreate the bookmarks, which might work around the problem. ---

Hi @Turf_Daz, no you will not lose your cue points and saved loops. However, just to be safe, I recommend that you backup your **djayMediaLibrary** database file to the cloud or an external drive first: > **[How to find your djay data and move it to a new device | Algoriddim Support](https://help.algoriddim.com/topic/using-djay/where-does-djay-store-data?os=mac)** > > This guide explains where djay stores playlists, cue points, MIDI mappings, recordings, and other user data on macOS and Windows — and how to move that data to a new device. ---

You’re welcome. No, crates should be fine too. My Collection playlists and the Queue are also saved in the djayMediaLibrary database. If you’re worried about it, you could also do a full system backup via something like Time Machine first.
