Hi Rob,
It looks like you just need to manually update both Roon Server and the Roon Remote clients on your Mac.
Here are the direct download links for you.
Here is the update for Mac server that is running as your core on your Mac.
And here is the link for Roon Remote once server is updated.
There may have been a technical issue on our side or yours that caused the update to not work as it should but these links should get you back up and running. Just do them in order and verify when done. I’ll be here and awaiting a response.
Thanks,
Wes
