Describe the issue

All local network devices disappear. If I reinstall Roon, and give access to local network, they turn up. Then after a few days all devices disappear from the Audio tab under Roon settings.

Describe your network setup

Wifi router, all devices connect to same router. No extenders, mesh or anything. All devices show up in the router settings.

Hi @Tormod_Guldvog,

Thank you for your post.

One of the myriad network security changes introduced with MacOS 15.x was MAC address randomization.

I recommend navigating to your Network settings (WiFi → Details) and checking whether the Mac in question is relying on a Fixed, not a rotating, Private WiFi Address.

This will not be a panacea - the team has a ticket for ongoing Sequoia issues which also match your reported symptom. Roon interacts with coreaudio, the Mac audio daemon, via the loopback interface. Sometimes, Sequoia will interrupt RAAT’s access to that interface. Our Developers are investigating the issue diligently and proving updates as available here: Roon on MacOS 15.0+ Sequoia: Audio Zones Disappear, Requiring Local Network Access Reset or RAAT/Roon/macOS Restart [Roon Investigating]

We hope to have a more fruitful update soon. Thank you for your patience.

Thank you! It shows as Fixed.

I disabled and reenabled local network access, restarted my Mac and the devices came back. Still working after 4 days. I hope you guys get it sorted.
