MacBook Pros not recognized as zones despite Roon Bridge and RAATServer troubleshooting (ref#FRBYVF)

Describe the issue

I have 2 MacBook Pros and neither will act as a zone or output. Both connect to Roon Core on a third MBP. I've installed Roon Bridge, troublshot RAATServer and still no luck. I have extensive notes. Please help/advise. Neither MBP shows "this device" in Settings/Audio. Play is only directed back to the Core MBP and a Schiit Modi DAC connected via USB (which works fine).

Describe your network setup

Wifi via Linkys Velop nodes with C4000GX router. Centurylink fiber. 140mb+ signal down/ 90mb+.

On each of your Macs, open System Settings > Privacy & Security > Local Network, and check that the Roon app is enabled.

Thanks for this suggestion. Here’s what I seel:

  • 2023 MBP M2 running Sequoia 15.3.2 - Local Network/Roon is/was enabled
  • Late 2013 MBP 2.8Ghz Dual-Core Intel Core i7 running Big Sur 11.7.10 - Local Network is not an option under Privacy/Security settings (yes, I’m trying to teach an old dog a new trick)

Hi @Ty_Montgomery,

We’ve seen a number of user where even with the switch enabled you have to toggle it of and then on again to make it actually active. Can you try that?

Toggled Roon and RoonBridge in Local Network - no change.
I did launch RoonBridge and see it is quickly changing from “running” to “not running” in the menu bar. Still can’t see “This Mac” on the MBP M2 running Sequoia. Nor can I see it from the MBP running Roon Core. Remote connection

s are enabled in Roon app.

On the MacBook Pros that you want to use as endpoints, start Roon and navigate to Settings > Audio. Select the gear for the local MacBook Pro: This Mac > System Output and select Device Setup. Switch Private Zone to the off (No) position. You may need to restart the Roon apps to get the change to show up quickly.

Thanks, but that’s the crux of the issue … the Mac(s) I want to use as endpoints do not show as This Mac (or local MacBook Pro, as you put it). Only the Mac hosting the Roon Server.

What you are showing is the Audio settings on the MacBook Pro running Roon Server (Office Mac). You need to start Roon on the other MacBook Pros (e.g., Ty’s MacBook Pro) and follow the instructions above to enable it as an end point. The Roon App needs to be running on the others but it will not be acting as a server for those machines.

Well, Roon Bridge on those clients should do the same, but using the Roon App gives you more control. I do this between a Mac Mini, a MacBook Pro, and even an iPad Pro if I want to treat it as a remote zone.

This screenshot is from the M2 MBP I want to use as an endpoint.

The Office Mac is another MBP that is running the Roon Server.

I can play from the M2 MBP but only through the MBP running the Server.

No ability to make it an endpoint or Zone.

In short, this M2 MBP is not showing up as This Mac in the Roon App running on it.

And … Roon Bridge is behaving erratically (running, not running) as showin a post above.

Understood. Sorry if I was a randomizing factor with my suggestions! I’ll watch to see if you get resolution.

No worries, happy for any input, Mark. I seek the same goal!

Hey Daniel, can you circle back on this topic? Note that I’m not getting anywhere and that RoonBridge is cycling from running and not running every second. Is that an indicator of why my M2 running Sequoia is not acting as an endpoint?

Hello @Ty_Montgomery,

Thank you for the update.

Could you please clarify your network setup? Based on the diagnostic report from your account, your Roon Server appears to be located in the 192.168.1.0/24 subnet, while both of your Macs (used as Roon clients) are in the 192.168.0.0/24 subnet.

This difference may indicate a network segmentation issue that could prevent proper communication between your Roon Server and clients.

Looking forward to your reply!

Thanks Vadim … this sounds promising. I’m on a home network with CenturyLink fiber internet as source. Signals run to a C4000GX router (provided by CenturyLink). I’m using Linkysys Velop nodes in bridge mode for a mesh network. Each MBP is accessing internet via WiFi on the same Wifi Network. I’ve recenty optimized the network and am getting 190mb download/150mb upload speeds. I can do admin on the network (with guidance, please).

Hello @Ty_Montgomery,

Based on this, it seems that your Linksys Velop nodes might be assigning their own DHCP addresses to WiFi clients. This could explain why your devices are on different subnets.

Could you please double-check your Velop configuration and ensure that the DHCP server is disabled on the WiFi network, or confirm that all devices are receiving IP addresses from the same DHCP source (ideally your main router)?

Let us know what you find!

Vadim … you unlocked the front door to the solution. Thank you!

TLDR: Ensuring all endpoint MPBs are in the same subnet is key. It works and I have full home syncing across 3 MBPs.

Long story: I spent a lot of time since your response in ChatGPT. We ran through firewall settings, subnets, Mac OS security, installs/reinstalls, etc. RAATServer was a pesky bugger to get in place. Once done, everything flowed. I even added an Ipad with a USB-C to HDMI so I can use a Samsung N850 Soundbar as fourth endpoint.

If others run into this issue, do what Vadim says and ensure your network is flat, your subnets identical and that firewalls aren’t stopping you. Terminal is your friend … if you can ping it, Roon can see it.

Hello @Ty_Montgomery.

Thank you for the update I am glad to hear that the issue is resolved. Enjoy listening your music.
