Good evening all.
I upgraded my MacBook Pro to MacOS Sierra V10.12 a few days ago, and from that moment my 3TB MyCloud was no longer visible in Finder and TimeMachine was no longer able to back-up.
I can still see the MyCloud device through browser access - up, responding and healthy running Firmware 2.21.119.
Also I can connect to the MyCloud device as per Shabuboy’s suggestion (here: Can’t access private folders in Finder on Mac OS X Yosemite ) but Time Machine continues to not find the back-up device.
I have also tried the SSH re-connect solution suggested here: http://support.wdc.com/knowledgebase/answer.aspx?ID=14987 - using the IP address - but my system replies “Connection refused” and nothing else seems to have changed.
Many thanks in advance for any help getting this frustrating problem fixed.
