I used Sonos for a long time on my Macbook Pro 2013, last year I moved to a new Macbook Pro 2017 and continued to use my Sonos with this newer Mac.
Now I would like to reactivate the old Macbook.
Sonos app itself is working but I can't add my Music Library.
Sonos asks for the admin password but then an error message appears, your Macbook Pro 2013 has rejected access to the Sonos System. No error code.
I followed many suggestions I found when googling this error message.
I deactivated file sharing and reactivated it.
I removed my Music folder from Sharing, added it again.
I move a folder with just 2-3 songs to a different location.
Then I realized on my 2017 that there is a "user" called SonosDMS which has access to my Music folder there.
So I tried to add a user SonosDMS on my 2013 and got an error message that this user exists, but it seem to be hidden. So, I used some Terminal commands to get rid of the user and set it up again, or let Sonos do it automatically (I think this is happening when adding the library).
Still getting the same error message.
Any other ideas apart from a clean install ?
This is how it looks before I add the Library
and while trying to add the Library for 1-2 seconds this "new" user is trying to get access to the folder (not sure what "loading" means)
I'm running macOS Sierra on the 2013 machine, same OS was on the 2017 machine.
