Hi

If you are having issues installing the Sonos app on your Mac with Apple Silicon the following link should help. It’s an official Apple article:

https://support.apple.com/en-us/HT211861

After a successful installation I further suggest you give it permission to update by going to:

1. Apple Icon Upper Left Corner on Menu bar
2. System Settings
3. General
4. Privacy & Security
5. App Management
6. Click Plus Sign (+) to add Sonos App *

 * The app should be found in your Applications folder. If not it wasn’t properly installed.
