My system is installed at a place that does NOT have internet. Sonos requires internet to look for a new controller EVEN THOUGH IT HAS THE LATEST VERSION! Great coding guys !
So, can anyone send me an earlier version of the controller so that I can get back to where I was before I updated the Controller + MacOS + iTunes; which I do at another internet connected site.

I think the last question and answer in this top pre-purchase FAQ link below, might be the reason why...
Sonos do definitely say, without exception, that an internet connection and a router is required. I don’t see how the Sonos developers can really be held to account here. This is perhaps more about some users seeking a workaround to operate their equipment without internet access, rather than any Sonos endorsed official route.
