Sonos App not working in MacOS Golden Gate Beta

Unfortunately everyone will say to use the web app because that’s what Sonos wants you to use now, and is likely the only option. The app and its native experience will be gone shortly, and lack of Golden Gate support is likely an indicator of its imminent incompatibility.

That said, have you tried deleting and reinstalling the desktop app, as that might provide a solution short term.

Sonos does not push for compatibility with Beta software. When the software become official, they begin working to make the app compatible and that can take weeks or months. 

Knowing that Sonos will soon retire the desktops apps is reason enough not to upgrade to any software that is in its Beta stages right now. Stick with what works instead.

Hopefully Sonos will begin to add more functionality to the web app and create a better user experience for us.

Try “Phonos Ultimate” from the App Store.

Sounds like an amazing app. I’ll bet its developer is one incredible guy. 

:-) you know it must be true!

Thanks for the suggestions. Just an update, deleting app and preferences and re-installing did not work. App still can't find system on network.

Downloaded Phonos Ultimate and we’ll give that a go!

As has been stated here, and in many other threads, Sonos doesn’t chase beta’s of OS releases. Just too many potential changes that occur over the betas, requiring too much programmer time to do so.
