I WAS running Roon from an M1 MacMini with 8 GB RAM, to a Mytek Brooklyn DAC, streaming only Qobuz. The only things I was running were Chrome, and Roon. Granted, Qobuz “resided” on the MacMini. I previously had iMessages open, as well as Mail, but I since closed them to conserve memory. I did check to see if there were any other apps open, and besides Finder, Roon, and Chrome, that’s it. Roon crashed A LOT, and for no apparent reason. I bought a Cambridge CXN V2, thinking that since this piece was truly Roon compatible (more so than the five year old Mytek), that it would be more “memory friendly”. No dice…Roon still crashes…A LOT! I tried to attach the crash report, but it states it’s too long to post…I am seriously about to dump Roon…I question whether it’s worth it.
Did you check if your crash is the same as this one, which is the most frequent macOS crash issue? A workaround is available:
Hi James,
Can you fill out the following for the support team
Thanks!
Daniel
Roon Core Machine
Include your operating system and machine info (Model, CPU, RAM)
Networking Gear & Setup Details
Your network gear (model of routers/switches) and if on WiFi/Ethernet
Connected Audio Devices
Specify what devices you’re using and their connection types, like USB/HDMI/Chromecast, etc.

Tell us how large your music library is, eg. “30,000 tracks”
Description of Issue
Tell us about the problem you’re having in as much detail as possible. Screenshots are always appreciated!
Daniel…
Thanks for reaching out…Here ya go…
Roon Core Machine
M1 MacMini w/8 GB RAM, MAC OS Ventura 3.2
Networking Gear & Setup Details
Xfinity XFI Gateway (Gigabit service)
Connected via ethernet…Wired from dedicated computer switch cabinet downstairs (professionally wired) to gigabit switch upstairs where A/V gear lis located. Both the Cambridge CXN V2 streamer/DAC and the M1 MacMini have their own internet runs, and each has very high quality RG6 cables.
Connected Audio Devices
Roon is installed on M1 MacMini (connected as described above via ethernet), and is streaming to my Cambridge CXN V2 (also connected via ethernet as described above). My only source of music is Qobuz, which I access via the CXV V2 streamer
Number of Tracks in Library
25,680
Description of Issue
Works fine, and then crashes…Opens up Apple crash log (which I copied and attached previously). I would then have to relaunch Roon to get it to play again.
Since then, someone in the community suggested running Roon Server along with the Core, clicking “Launch on Startup”, which I did…It still crashes, but now the music continues to play after the crash…I just can’t see the interface until I relaunch Roon…Any assistance would be really appreciated! Love Roon, but this is irritating as heck, and I feel like I’m really NOT getting what I paid for…THANKS!
Jim Helman
You wrote that you couldn’t, and nothing was attached to your first post 
How the heck do I attach a file? I can only see the option of a hyperlink…
jim
I don’t think you can attach any files except images, but it should be possible to copy the text content of the Mac error message and copy & paste the text. If it’s too long, copy and paste a part of it, the first half would be most interesting.
But look if the error message mentions “.NET ThreadPool Worker” in the line saying “Cause”, in which case it would be the issue that I linked further up
No instance of the word “Cause”…14 of “ThreadPool”, but none of “ThreadPool Worker”
My mistake, I misremembered - “Cause” does not appear, it’s on the line “Crashed Thread”. A typical one from the thread I liked looks like this. I bolded the most telling part (the number may differ)

I’m just a fellow user trying to help …
The linked thread has a lot of information, maybe it looks familiar. I posted a typical crash report from this thread, above.
Hi @James_Helman,
Since you mentioned your crash reports don’t contain the “ThreadPool Worker” line suggested by other users to be the common symptom here, are you able to upload the main summary text of the crash report here?
We’ve pulled diagnostics from your Mac Core in the meantime. It’s possible you’re encountering an isolated - and resolvable - issue independent on the known Mac crash.
Thanks Connor…Here ya go:

I appreciate your help!

It’s in both
OK, so the solution you suggested was to run Roon Server from my iPhone or an iPd, but that really doesn’t solve my problem. What separates Roon from just listening to Qobuz, or Qobuz via Audirvana, is the interface…the plethora of information that we get to enjoy while listening to music. If I can’t do that while viewing on the 75" panel I have, and am relegated to “enjoying” that information on a tablet or a phone, I’m out. Roon tech support is essentially non-existent. I appreciate the help from folks like you in the forum, but there are enough people reporting the same incident when using Roon with a MacMini, that they should either have real tech support to engage with customers, or FIX THE PROBLEM.
No, the suggestion in the linked post was to install Roon Server on the core machine, which would be your Mac Mini, in addition to the full Roon app. Then the Roon Server runs separately on the Mac Mini and you can still used the full Roon app on the Mini to control it, as well as the iPad/iPhone. That gives you the exact same user interface that makes Roon what it is. Just the server is running separately from the Roon GUI on the Mini.
As for fixing the problem, they are working on it, as they posted in the linked thread. Sometimes it’s just difficult. I think it took them a long time until they could even reproduce the problem - it’s not as if it’s happening for everyone. It sucks for those affected, but that doesn’t make it easier to fix
And I did try that “solution”, but it really doesn’t solve anything. Occasionally, when it crashes, Roon Server will keep playing the music while I reboot the full Roon app, but most of the time, the music stops as well. Not really a fix, per se. Don’t get me wrong, I REALLY appreciate your help!!
Jim
You are welcome. I misunderstood when when you wrote “to run Roon Server from my iPhone or an iPd”.
I’m afraid that’s all I can do here. I never had that problem (but I run just the Roon GUI on my Macbook, the Core is ROCK) and I had to assume that the workaround should, well, work around it, based on what the Roon guys wrote. Pity if it doesn’t. The rest must come from Roon and we can only hope that they finish the fix soon.
Agreed! What do you run ROCK on?
