[UPDATE]
I’ve restored my MacBook Pro from Time Machine to Friday April 17th, and guess what?
There’s a sign of the Duo back from the dead. It still doesn’t showed on my mac, but i hear the drives start spinning and off again and again. I leave it for an hour. then i restart my Mac.
And the Duo was working normally again!!
I’m on OSX El Capitan 10.11.6, the last thing i remembered i’ve installed Security Updates and System Updates from Mac App Store this week. So i roll back to Last Week. and it works.
Now i’ll stick with 10.11.6 (15G1421), I did not want to update until i get clarification on this.
