Yes, they do.

I think you might have been trying a little early, the software takes a little while to launch on all platforms sometimes.

You can get all the software here: https://www.sonos.com/en-us/controller-app

checking on my mac Sonos says there is an update available (currently 11.1)

Will this OS mac app update to S1 or S2?

I do not want S2 as I have one play 5 (gen 1) and I still want to group it in with my existing other 9 products, and I have read S2 is irreversible so once split off you cannot go back, or have not understood correctly.

S1. You have to make the change to S2 from inside the S1 app.

thanks

I cannot seem to download the S2 to my MacBook. Cannot even get to the terms and conditions. When I click on the update button in the notification that comes up in S1, nothing happens. When I click on the download button on Sonos.com, it just takes me to one or other of the S2 articles.

On the downloads page:
   https://support.sonos.com/s/downloads?language=en_US

there is a direct link to the macOS S2 app:
  https://www.sonos.com/redir/controller_software_mac2

Both of these links work for me.

PWT - thanks! That worked perfectly! Appreciate the help.
