i updated my MacOS app this morning and it stopped connecting to my Sonos system. My android phone app, my Wifi and Sonos speakers were working just fine so the problem had to be on the Mac itself. Here’s a fix that sorted it - had to resort to Gemini to find this. Am putting it down here for the rest of community
This is a very common headache with macOS 15. Because your Android app connects without a problem, we know your Sonos speakers and Wi-Fi network are working perfectly.
The issue is entirely isolated to how your MacBook Air is managing network permissions for the desktop app.Here are the steps to fix it, ordered from the most likely culprit to the most thorough:
1. Toggle the "Local Network" Permission (The Most Common Fix)macOS has a strict security feature that blocks apps from communicating with devices on your local Wi-Fi. Even if the permission toggle looks like it's already enabled, macOS updates notoriously cause this setting to "silently fail." You usually just have to wake it up.
- Open System Settings on your Mac.
- Click Privacy & Security in the left sidebar.Scroll down on the right and click on Local Network.
- Find Sonos in the list.
- Toggle it OFF, wait a few seconds, and then toggle it back ON. (If it was off to begin with, simply turn it on).
- Force quit the Sonos app and reopen it to see if your system appears.
In my case the toggle had gone off after the app update. Clicked it on and hey presto, the Controller is now connected to my Sonos speakers again
