I just bought this Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter for my new MacBook Pro (2016) to connect it to my old Thunderbolt Display, but realized that none of my USB ports or Thunderbolt port work (so no daisy-chaining).

Is it something wrong with my setup or is this connectivity not supported by Apple's official Thunderbolt 3 (USB-C) to Thunderbolt 2 solution?

This does not sound like "to Thunderbolt 2" adapter to me, since it only supports multimedia.

    What model is your old Thunderbolt display? And what do you mean by but realized that none of my USB ports or Thunderbolts port work? Just to clarify, does your display work with this cable? If so, what is it that you're trying to do that isn't working?

    My Thunderbolt Display is from 2012. I just realized that USB/Thunderbolt ports work when I plug the cable off and then plug it on back again, but it works only for ten of minutes and then it stops working. I have to plug it off and on again. I am merely using USB keyboard in my Display and Wacom Tablet so this is really an inconvenience.

Connecting 2 Thunderbolt displays using daisy chain with the Thunderbolt 3 (USB-C) to Thunderbolt 2 didn't work for me until I upgraded to the latest Sierra build. (10.12.13) now everything is working as it should. If upgrading didn't work for you I suggest that the adapter is faulty.

    What about the ethernet slot in the display? Is it recognised by the mac?
