Recently upgraded to:
MAC OS 10.13 High Sierra// followed by SONOS Controller 8.1
SONOS now unable to add my two iTunes music libraries that it has been accessing fine for the last several years. (These libraries are fairly large - 47 Gigs and 99 Gigs and are located on my iMac along with the SONOS controller program.)
Followed all steps on the various levels of the SONOS troubleshooting website - re-set firewall settings, revised music sharing settings and computer naming protocols and tried showing the path to the libraries in different manners.
Nothing prevents the receipt of error code 1002 and the message that SONOS could not add the library.
I just spent 20 minutes with the initial level SONOS support representative on the phone and he had no solution.
Any suggestions appreciated. I am a big user of SONOS and have ten Connect or Connect Amp devices in my house and it is frustrating to have this basis function suddenly not work.
