Heya!
Same issue that I've seen others had but wanted to start a new thread instead of just reviving an old one.
Updated to Sequoia in the studio, 15.3.1, updated DADman to 5.8.0.8, soundflow 5.10.3.
Double checked sound flow permissions, Accessibility granted, Full Disk, Local Network.
DADman the same, Accessibility, Full Disk, Local Network.
I tried out the solution from Soundflow app opens, but there is nothing on the screen. I can't see any apps, etc. #post-15 but that didn't seem to solve anything for us.
DADman seems ok with finding other devices on the network (MTRX, DADmom). Stream Decks seem to find decks ok. Things just lock up when DADman try to find the MOMdeck.

Same problem here. For some reason the Momdeck is not found on the network more than often. Restarting DadMan sometimes works, sometimes not. Rebooting system works, sometimes not. Why does it seem so unstable?
In reply toCameron_Frankley⬆:Ron Aston @Ron_AstonI just wanted to add that I've been dealing with this exact same issue for more than a week now. I just assumed that it was something with my PT system, suddenly and couldn't figure out what might've changed. Then I found this thread.
I can sometimes get it to work by trying different things but so far that hasn't been a a consistent way of making it work again. Up until now it's been fantastic as well as reliable. I'm running Sequoia 15.4.1 and all of my software is up to date as well as the firmware in my StreamDeck Plus. HELP!
In reply toCameron_Frankley⬆:Andrew Scheps @Andrew_SchepsHi all,
Sorry I missed this thread the first time around. I know a bunch of people who aren't having the issue, so we're looking at something specific. One thing is it hasn't been tested in OS 15.4.1, so while that may not be the issue I can't confirm that it would work.
Can you all tell me whether you are running MOMDeck on the same machine as Dadman, and any other network type stuff that may help point me in the right direction? It's working fine here so it's hard to troubleshoot...

hey!
Has anyone has this issue since PT 25.10.0.144 / new sound flow implementation?
My MOM has just completely disappeared from DADMAN and it's making me rip my hair out!

Andrew Scheps @Andrew_SchepsHey @Dave_clauss ,
It’s a Mac OS thing and it really sucks.check out the steps here to get it going. Not everybody has to do all of these steps, it seems to be different on different machines.

Chris Shaw @Chris_Shaw2025-11-24 15:17:17.131Z2025-11-24 17:22:11.442ZJust adding my experience.
I was having this issue as well and Kitch's solution above is working for me.
My system is set to load DADMan automatically via the "Auto-launch Apps" (MTRX) option in the Eucon Menu bar icon:
Once DADMan is running and waiting to connect to MOMDeck I just toggle SF on and off in System Prefs >Privacy and Security >App Management". I toggle it off, enter my password and click later when asked to Quit and Reopen SF, toggle it back on then Click Quit and Reopen". This way you only have to restart SF once and, for me at least, requires fewer steps than Kich's solution. YMMV
It's a pain, but manageable. Once it's open and running it's solid
In reply toCameron_Frankley⬆:Ron Aston @Ron_AstonHi Andrew - In my case, I have a 2 computer setup. My M1 Mac Studio Ultra is my main computer and my M2 MacMini Pro runs DaDman and MoMdeck. Both computers are running MacOS 15.4.1. I have no firewalls or other network protection enabled currently. I don’t know what changed here but this all started for me a little more than a week ago.
Andrew Scheps @Andrew_SchepsCan you try running MOMDeck on the same computer as Dadman?
- In reply toRon_Aston⬆:
Andrew Scheps @Andrew_SchepsWhen did you upgrade to 15.4.1?
In reply toCameron_Frankley⬆:Ron Aston @Ron_AstonAhh yes. I forgot to mention that the MoMdeck IS running from the same computer as DaDman same as it was from day 1 and had worked great ever since. I updated to 15.4.1 approximately 2 weeks ago and everything seemed fine after that update. I think things might’ve started going south after updating the MoMdeck software from the SF store download, but I can’t say for sure.
Andrew Scheps @Andrew_SchepsWhen you start Dadman and MOMDeck, what does the Dadman device list look like?
In reply toCameron_Frankley⬆:Ron Aston @Ron_AstonWhen I startup the DADman Mac mini Pro, the MoMdeck is showing the default 'factory' button assignments....Spk1, Spk2, etc. When I launch DaDman (like I just did), it can't seem to find my devices, like Cameron posted above.
When I hit Cancel and open the Device list, all that appears there is just the MTRX Studio.
I've also noticed that there's evidently a fan issue but the unit has been functioning fine.
I've tried various methods to eventually get the MoMdeck to appear in the Device list including quitting DaDman and Soundflow and the relaunching SoundFlow, then Dadman and sometimes the MoMdeck will suddenly appear in the Device list after DaDman successfully loads without getting stuck, but it only works every so often. I'm also running DaDman 5.8.0.8.
In reply toCameron_Frankley⬆:Ron Aston @Ron_AstonAlso....Here's a screenshot of my MoMdeck Monitor Profile for layer 1. I'm using 3 of the 4 layers.

I'm running 15.4.1. Dadman and Momdeck on the same machine. Different Vlans for Eucon, Dante, etc. Total of 4 Vlans on my main machine. I have DAdman starting automatically when logging in. I noticed that that seems to interfere with Soundflow booting properly. Sometimes Momdeck is found when I restart Dadman.
Andrew Scheps @Andrew_SchepsI'm on 15.3.2 here, so it could be 15.4 and beyond. I've got 3 vlans + wifi and it's really solid here. I'll see if I can find anybody running something later than 15.3.1 to try it out.
In reply toCameron_Frankley⬆:Ron Aston @Ron_AstonI wish it was working in any way here. I just updated a 2nd volume of my Mac mini Pro (DADman computer) the was formerly a Ventura Startup v

In reply toCameron_Frankley⬆:Andrew Scheps @Andrew_SchepsOk, I've updated to 15.5 and it's still working fine on SF 5.10.5.

In reply toCameron_Frankley⬆:Andrew Scheps @Andrew_SchepsOk, I think I have finally got a repro case. I need to make sure the steps are 100% repro and then I'll file it. It's some sort of SoundFlow

In reply toCameron_Frankley⬆:Andrew Scheps @Andrew_SchepsCan you guys all try rolling back to SF 5.10.4 and seeing if that keeps things working for you? It definitely does here.
