Can I use a Thunderbolt 3 to Thunderbolt 2 adapter with Codex Docks?
Following the instruction at https://support.apple.com/en-gb/HT207266, the official Apple Thunderbolt 3 > Thunderbolt 2 adaptor is bi-directional and can be used to connect Codex Docks. macOS Sierra 10.12 or higher is required to use Thunderbolt 3 machines or Docks (including with a Thunderbolt 3 to Thunderbolt 2 converter).
