· Title: Mac Mini M4 on macOS 27.0 (26A428) – Missing All Roon Ready EndpointsCore Machine: Mac Mini M4 running macOS 27.0 (Build 26A428) over Wi-Fi.Issue: Roon Server is completely failing to discover any network audio zones. The "Roon Ready" header section has vanished entirely from my Settings > Audio menu. My mobile Roon Remote apps connect fine (incoming), but outgoing endpoint discovery is completely dark.Endpoints Missing: Eversolo DMP-A6, Eversolo DMP-A8, Cambridge CXN v2, and Bluesound Powernode.Troubleshooting Done: Completely rebooted the entire network, factory reset the Eversolo streamer, toggled Local Network security permissions off/on, and verified the firewall. The streamers are working perfectly and are fully visible inside their native manufacturer apps (Eversolo/BluOS/StreamMagic).

Welcome to the forum, this is a known issue with macOS 27 and Roon. Workarounds are here:

Roon is working on a fix and hopefully it should not take very long:

Hi @tcarlton777,

The team is working to restore network discovery for Roon on macOS 27 Golden Gate. Apple security severs Roon’s network connection at a deep level, preventing RAAT from generating multicast traffic.

You can find workarounds at the link shared above.

The team will announce a fix broadly on Roon Community as soon as it’s ready. We appreciate your patience in the meantime.

Hi @tcarlton777,

We released a hotfix, so please update to the latest Roon build and see whether that restores endpoint discovery. The hotfix notes are here: Roon 2.73.1 hotfix is live. Let us know how that goes!
