Describe the issue

Installed latest update and no audio devices found

have just installed the latest update on a dedicated Mac Mini running as the Roon core, all network devices have disappeared in Roon. All are on the same network and nothing has changed. other software can see all the devices. Restored from a backup from a month ago but this hasn't fixed the issue. Have restarted the Mac Mini.

Describe your network setup

Deco BE65 three of these

I have restarted both the Mac Mini and the network to no effect. The network pic shows many of the devices on the same network.

Same issue here. Restarting my Roon Server (Mac Mini M4) fixes the issue. Also, after some time the audio devices reappear but there is no pattern to the restoration that I can see.

If restarting doesn’t work try the following on your mac:

System Settings → Privacy & Security → Local Network

Toggle Roon Off and then back On and then restart Roon Server.

This fixed it, however I run my Mac mini headless so the minute I powered it off and then reconnected it It stopped working again. To keep toggling these controls off is not a solution it’s merely a work around

Not sure if Roon can do anything about it, it’s more of a macOS issue unfortunately. macOS 15.4 should be released next week, hopefully it fixes this issue.

I’ve seen the same problem in Edge Browser’s Local Network access, so it’s not just related to Roon.

if its not a Roon issue why did it only occur after this update?

It’s been a problem for many updates for many users.

Hi @Grant_Harris ,

Thanks for letting us know that toggling the Local Network Access setting temporarily resolves the issue. As @DrTone mentioned, this is more on the MacOS side than Roon, but we are tracking these kinds of reports in an investigation ticket. Once then next MacOS update is released, please let us know if there is any improvement in the behavior, thanks!

I am installing 18.4 release candidate so will let you know if that fixes the issue

I assume you mean 15.4 macOS. 18.4 iOS won’t help.

Sounds good @Grant_Harris, let us know how it goes! :+1:

So far so good, interestingly it came up with a pop up asking if I wanted Roon to access local network.
Will report back over the weekend.

I think it will do that after every update as well from now on as part of Apple’s security checks and balances. So if you run headless this is going to be a bit of a pain for you.

Every time Microsoft Edge updates on my iMac it gives me the same prompt asking me do I still want to allow Network access to Edge.

Thanks for the update @Grant_Harris ! Hopefully everything remained stable, but when you have a chance, please let us know how further testing over the weekend went!

It all seems to have been ok
