Hi there,
I’m experiencing a recurring crash with djay Pro (version 5.2.9, build 61228) on my Mac running macOS 15.3.1. The app crashes with a segmentation fault (SIGSEGV) while interacting with the interface—specifically, it seems to occur during a collapse or expand action on an NSOutlineView.
Here are some technical details from the crash log:
-
Crash Reason:
EXC_BAD_ACCESS (SIGSEGV)
-
Exception Codes:
KERN_INVALID_ADDRESS at 0x0000000000000010
-
Faulting Thread: Main thread
-
Top Frame:
objc_msgSend called with a null or deallocated pointer
-
Related Frameworks: Foundation, AppKit, likely involving NSMapTable and NSOutlineView
The crash appears to happen here:
-[NSOutlineView _doUserExpandOrCollapseOfItem:isExpand:optionKeyWasDown:]
followed by a message send to a bad address in:
-[NSConcreteMapTable removeObjectForKey:]
This issue has been happening for months and I keep telling y’all there is something wrong with the app, and I keep being told that the team is unable to recreate it. It keeps coming back with the same invalid memory message, where it’s trying to access something in the framework that is not there.
What is going on??

As I don’t have access to your crash reports, unfortunately, there isn’t a lot of additional support that I can provide here. However, please feel free to share any other details about your crashes here that you think will be helpful in diagnosing the issue. I hope that helps!
Thank you for the swift response. I will submit a ticket, but can this please get a little more light from the support team?
The last few times I had this issue, I’ve been told it’s been fixed, or that the team can not recreate it. I think this needs really to be looked a little more deeply. The crashes occur every other event, and as a wedding DJ this is absolutely detrimental. I ran the program today, and as I was searching for a song the program completely crashed. Nothing else was being done other than me searching for one song. Why do I keep having these crashes?
You’re welcome @djsunkisst. I fully understand your frustration. Unfortunately, sometimes these issues are very isolated and directly related to a super specific software/hardware setup combination. So, troubleshooting the issue can be really challenging without being able to replicate it. This is why it is so important to gather as much contributing information as possible to help our teams to replicate the issue, properly diagnose it and ultimately develop a solution. It is very hard to provide a solution if you cannot clearly isolate the problem. I hope that makes sense. Your crash reports should provide some helpful clues though.
EDIT: can you please provide more specific details about your Mac hardware and any other connected DJ hardware including firmware versions? Thanks!
Thank you again for the response, though feel like I am being gaslit here a bit. I am very confident that it’s not a hardware issue. I’ve verified that I am running the the latest driver (4.0.1) for the controller I use, which is a DDJ SR2. And I am experiencing this problem on an brand new M4 Macbook Pro with 24 gigs of RAM, running the most up to date version of Mac OS, and the latest version of Djay software.
I’ve experienced this before on an Intel Mac, decided to upgrade, and still have this issue.
I strongly believe this lies within the code of the program, not what hardware I use.
I posted a video of the incident here:
As you can see, I was just doing a simple search for the next song in my library to play and the program just absolutely failed mid dance floor.
I hope this video sheds more light on this problem and we can come to a resolution.
A little more context, I am going to say again as I’ve repeatedly said before in other reports. It may have something to do with Beatsource. I just checked the last song that was playing at the time of the crash, and what do you know…? It was a Beatsource track.
I’m telling y’all there’s something funky going on with Beatsource!!
Additionally the day before, I did not have a full crash, but I did have a stutter. The program stopped both tracks and I had to hit play again to get them going. Checking my recently played from that night, it also happened with a Beatsource track.
I was playing the Beatsource track on the left, went to mix out of it, hit an effect while fading in the second track ‘Two Dozen Roses’, and the program freaked out, and stopped playing both tracks. I had to hit play two times for it to recover and start playing that second track again.
I am seeing a recurring theme here with Beatsource.
Hi @djsunkisst, thank you for the Mac details along with the video, screenshot and additional context for the crash. This should be very helpful for the engineering team in diagnosing your issue. I have passed on all of the details you shared here to our official support for further review. Thanks again!
EDIT: sorry, I did not mean to imply that I thought your issue was specifically a hardware problem. I was trying to explain why the engineering team was not able to replicate your issue and troubleshoot it previously. Often these isolated issues are related to a specific combination of hardware and software. If the team cannot replicate the issue, it becomes challenging to troubleshoot further.
Given that this seems to be linked to Beatsource, I suspect there could be a corruption within your djaymedialibrary database.
Can you please upload your djay Media Library database file to your Google Drive/Dropbox, enable sharing permissions, then share a link to here or send it to me in a DM?
- On macOS it can be found in ~/Music>djay. Thanks!
It’s okay, and I apologize. I’ve just been quite frustrated with everything going on with the program. I understand you’re doing the best you can to solve the issue. Here’s the library file on Google Drive:

No problem @djsunkisst. I totally understand your frustration. Thanks for the db. I’ve passed it onto engineering for review. I’ll report back here when I have more news. Also, please note that the Official Support team via email is different from the Community Support team here so it’s best to communicate with only one of us so there’s no accidental loss of information.
Good morning, just following up. I haven’t received anything from the support team yet unfortunately. Is there any way this can be escalated up at all? Going into a busy next few weeks of weddings & events, and want to ensure that no more issues arise. Thanks!
Hi @djsunkisst, our engineering team is still investigating this unfortunately. I’ll let you know as soon as I have more information though.
Hi again @djsunkisst, engineering is asking if you deleted any playlists at any point in the session and then hit undo CMD+Z. Please confirm. Thanks!
Hey there! I can confirm that no playlists were being deleted at the time or before the crash. it has happened in the past where I’ve had a crash because of a playlist that I deleted while I was mixing, but not this time. Just scrolling through playlists searching for the next song.
Actually, I may have before arriving to the event if the crash logs show I didn’t restart the program before arriving and setting up. I’m not sure if that can be seen in there. I would have arrived at about 7:30 AM that day, Central Time.
Thanks for the additional info @djsunkisst
Good morning! Just putting a little more spotlight back on this, and some additional updates. Ran three more events last week, and still noticed the problem happen consistently when a Beatsource track is introduced. This happened at least once at all three events. Sometimes I could be doing nothing at all, and the program would stop playing whatever is on the decks. I do have some new footage of it happening in the moment, just need to comb through it and upload.
This time no actual crashes with logs, but at all three events whenever a Beatsource track was playing, it would randomly stop playing, then recover a few seconds later. Last night was the worse, where it happened about 3 different times throughout the night.
Hoping the team has some updates soon! Haven’t heard anything back other than ‘we’re still investigating’.
Thanks!
I know you mentioned it could possibly be a media library corruption…in the meantime is there a way on my end that I can start fresh with a new media library? Would that work?
Hi @djsunkisst, thanks for the additional info - this is very helpful. The team believes they have identified the problem and are working on a fix. I’ll share more news when I have it.
The latest feedback you shared, sounds like it could potentially be an internet speed issue. Does your Beatsource/Beatport subscription include the Offline Locker? If so, can you please test to see if you experience the same issues with tracks that are in your offline locker?
Regarding the database, you can start with a fresh database, but you will lose your saved hot cues, saved loops and My Collection playlists. If you’d like to test this, I can guide you through the database backup process and how to create a fresh database. Just let me know. I hope that helps!
Hi! Exciting to hear they are working a fix! 
I found a clip in my footage of one of the dropout/stutters from last night. I noticed actually at the time of the stutter, a Beatsource song was not playing, or loaded in any of the decks. I did notice however a few songs before I did play a Beatsource track. One was downloaded already, and the second ‘Heartache on the Dancefloor’ was not in the offline locker. Not sure if the stutter is still related to Beatsource there.
Here’s a video of the stutter: https://youtube.com/shorts/H18fUfeMogg
And I’m attaching the recently played log. ‘I Gotta Feeling’ was the active track at the time, and the stutter happened right as I tried to mix in the next song. No effects used, just dropped it in on the one.
