Recently upgraded to Sonos 15.2 from 15.1.  The new version won’t work on my old Mac.  How can I revert back to 15.1?  That is the last version that will work with my old Mac.

If you have a Time Machine backup you can restore the old version using the previous dateline for the Applications folder.

However, that’s only the controller, and not the software that is installed on the speakers. I don’t know of any way to walk that backwards. You could try updating from the 15.1 client, but there’s no guaranty that Sonos keeps that data for use on their servers. 

I know you don’t want to hear it, but it may be time to update your hardware and OS.
