update to macOS Tahoe

Settings are same as AJTrek1. (Except I don’t use FileVault or Firewall) Local Network access is on for Sonos.

I ddi speak to Sonos, twice, and they say call Apple/the hardware vendor. Not a great answer since it clearly is related to OS 26. (was working fine before the upgrade)

The error it throws;

Sonos has no clue nor do I.

What device are you using and is UPnP turned on?

When you ask device, do you mean the computer with the problem? It is the aforementioned Mac Min M1 now running Mac OS 26.

UPnP ia turned on at the router, yes.

Device in “Community Speak” refers to your phone or tablet where you can do anything using the Sonos App. The desktop app is just a player. Go to the Sonos App on your device and follow the paths as shown starting from the home page:

Profile > Privacy & Security > Connection Security

• Authentication > Off 
• UPnP > On (Must be enabled as it has a direct correlation to the Desktop App)
• Guest Access > Off 

Had same issue, all I had to do was in the network privacy settings turn sonos off and on

You were fortunate. For others the settings for Mac are necessary (regardless of MacOS) with the exception of FileVault which is on by default in MacOS Tahoe 26.0. The user can choose to turn it off if desired.

The settings for the Mobile App are optional except for UPnP which must be on. Turning it on at the router level does not negate the requirement to do so in the App.

Actually, I do all the system management from my desktop app. It does have the same functionality as the device app. In fact, it was the desktop that first allowed adding local music to Sonos.

Regardless, the settings on my iPhone are the same as yours except I allow Guest Access for obvious reasons.

I will add, the Mac OS Sonos apps works correctly on my MBPro notebook running 15.7/Sequoia.

This was happening to me as well, and I had everything set fine according to  (e.g. Firewall is turned off - https://support.sonos.com/en-us/article/configuring-macos-firewall).

What fixed it was Settings / Privacy & Security / Local Network. Sonos was already turned on - I toggled it off and then back on again, and the app was able to connect.

I seem to remember doing this a few months ago with Sequoia as well.

Thankfully I can always access via my phone or iPad, plus via the web at https://play.sonos.com/en-us/web-app - but it’s nice to have the local Mac app working again.

There’s a programmer type who frequents this forum (and has written his own Sonos interface software) who has said that Apple’s code for the local network setting (and I’m paraphrasing!) was poorly implemented. I’m not overly surprised to read your issues, and glad it’s working again for you. 

doogm!

That is so obscure. I thought about toggling all the Sonos prefs in SysPref but didn’t.

So, I just did toggled Local Network off then on and that solved the issue. The Sonos app is now connected.

Thanks for the push.
