Roon Core 2.0 crashing constantly on Mac Mini

I run my Roon core on my older Mac Mini Server, which is capped out in terms of software updates at macOS Catalina 10.15.7.

Recently, I’ve noticed that Roon is crashing within minutes of launch, every time I launch it. I was just trying to play an album and I had to launch it in order to start the album. I didn’t make it through the first track before it crashed. I re-launched it and got to about the middle of the second track and it crashed again so I gave up. Playback is not required for the core to crash. If I just launch it and leave it alone it crashes as well.

I’m on the latest version of the core (2.0 build 1311) but this started before that version was released.

The crash log (the head of which I’ve attached) says that the crash is a SIGABRT, which means that the app actually deliberately crashed itself. Perhaps an unhandled exception or something along those lines? (Also, .NET? Eww.)

Probably the known issue from this thread. There is a workaround here but no solution yet:

Using Open Core Legacy Patcher many older Macs can be updated to Ventura.

Thank you. I’ve just installed RoonServer, so we’ll see how that goes!

Well, it’s a couple of days later, and the server is still running. The combined app would crash within 10 minutes, playback or no playback, so this is an improvement. Time will tell whether it’s truly robust. Thank you for the pointers!

Sadly, the server was not the solution. It crashed less, to be sure, but I still had crashes when playing music, depending upon the destination device. It seemed to be pretty solid for my Roon Ready Trinnov, but it crashed when used with AirPlay.

For other reasons, I finally upgraded my Mac Mini from an old Intel Mini to a current-generation M2. I did a clean install of Roon on that new machine, and then restored my data from backup following the guide.

I’m honestly reluctant to post anything lest I jinx it, but it has been solid so far. I have played music to the Trinnov, a Sonos player, AirPlay devices, and a USB-connected DragonFly.

Fingers firmly crossed that it continues to work. I hope that others who are having the same problem will find a solution.
