I read the community blog most days - passes the time.  

Seeing all of the sometimes agonized comments prompts me to say that I have been a Sonos user for several years, have updated and upgraded the software and hardware as needed, I use several different Mac systems and a Synology NAS to access Mac music, Audible books and other books on various local library files.  It all works and has caused me no trouble over the years.  

I added a Roam, worked perfectly first time, and continues to work as advertised.  The Soundbar update was easy.  Adding new Sonos surrounds was also a breeze.

I am not a Sonos, Mac, Network or It specialist, I just follow the instructions, and, guess what, it works!
