Thank you (all) for this.  I truly appreciate this.  I’m not a tech guru, but I was able to get Sonos back up  and running for my wife’s MacBook Air and my Macbook Pro.

I haven’t done a lot of study on it yet, but thought I”d ask: is there a similar process for iOS, as I have the same issues on my ipad and iphone.

Thanks

You can, if you so choose, delete and reinstall, the effect would be the same. However, Apple hasn’t changed the way iOS updates apps, so just running the update from the Apple Store works as it always has, properly. No need to delete, unless you want to, or feel the need. 

I thank “Wintegrations” for that answer.  I am using Sonos S1 Controller on Ventura.  I went to Applications, found ‘Sonos S1 Controller.app’.  I right clicked and chose ‘Package Contents’.  It displayed a folder called Contents.  I opened that folder and saw another folder called MacOS.  In that folder I found ‘Sonos S1 Installer’. I dragged that file/app to the App Management within Privacy and Security.  I relaunched the Sonos Controller and updated Sonos like normal with no errors.

Thanks again!
