· Roon is not recognizing all of my playback devices
· No VPN. Router - Verizon Fios. there's a Verizon Fios extender. I updated to MacOS 27, and am now at 27.0.1. that's when it stopped recognizing my components
This may be the well-known problem with the latest macOS (27). Do you see a banner with a blue background at the top of this page?
If so, follow the instructions there.
If not, a quick search in the forum will reveal several threads explaining what you might be experiencing and offering suggested workarounds.
Good luck
just updated to macos 27.0.1 and now my macbook sees again my roon device !!!
Golden Gate (macOS 27) has some overzealous security features that flag Roon as a threat; this can cause device discovery to fail, as the OS limits Roon/RAAT’s local network access.
There are incoming reports on the forum that the latest macOS update to Golden Gate relieves these symptoms, but rest assured our team is also working on a solution from the Roon side.
In the meantime, you can follow the steps listed in this article to restore device discovery on a per-session basis if this occurs again:
Yes, I see the banner. I did everything on the list except for the work in Terminal. I don’t like working in Terminal as I don’t really understand the interface. I’d rather not attempt those steps unless I really need to.
I have MacOS 27.1. No change.
this part confuses me:
I don’t know what the Roon server app is, or what it’s about. I just launch Roon when I want to use it and have never interacted w/ the Roon server app. I didn’t even know it was there. Roon is in my applications folder, and I launch it from the dock.
When I launch the Roon server app, nothing happens. when I clicked the roonserver in the MacOS folder, I got the following error message.
Neal,
Simply put, the Roon application software does run on your machine, Yes. From it you control what you play etc…
But there is also a separate but connected (‘different but equal’, if you like) server system necessary for Roon to work. It’s often something that is set to run when you start your machine.
Do you see this in your Menu bar (the strip at the very top of your desktop)?
In my case (the leftmost icon), the first line (greyed out) tells me it’s running.
That is the best place to start Roon Server…
What do you see?
Then the best thing for you to do now is run those commands in Terminal.
I’d say we understand your concerns. But if you go slowly and carefully, you should be OK. Double check each one (observing case, for example) before pressing Return.
Hey @Neal_Hemphill1,
Thanks for the screenshot of the macOS menu bar and for staying with this. Have you tried the Open Package Contents method from that article yet?
Let us know if this helps, otherwise the Terminal commands are currently the best way forward.
That did it! Thank you. And thanks to Mark Sealey for the screenshot and for making me aware that the Roon Server app exists on the Menu Bar.
I had tried to work through this before, but when I clicked on the Roon Server App in settings, I didn’t see anything happening, so I didn’t understand.
So - thanks to all who guided me through this!
Fix is out to both production and EA. If you are stilling hitting issues please tag me
