Describe the issue

My Sony TA-ZAH1ES plugged on my iMac doesn't appear anymore on my audio devices. It briefly shows up and then disappears from my audio devices, as well as my iMac. Roon Server is the Nucleus One.

Describe your network setup

Nucleus One is directly plugged to my router. My Sony TA-ZH1ES DAC is plugged to my iMac.

Hello @Vincent_Baudoin,

Thank you for reaching Roon!

macOS Sequoia (version 15), has tighter (and more obfuscated) network security settings than preceding MacOS versions.

Can you please navigate to macOS System Settings > Privacy & Security > Local Network, and make sure Roon is allowed.

If it is already enabled, toggle it off and on again. Then reboot your Mac, and see if the same issue persists.

Thank you so much @vadim ! It worked like a charm. I already re-toggled the access but didn’t reboot my Mac… All the best mate.
