I can't be the only person who wants this, surely? But I can't seem to find anything. I have a 2012 iMac and some peripherals with USB 3.1 type C connectors. I want to buy a hub/dock that will connect to my iMac (any way) and which has at least one USB 3.1 type-C port on it. I can find lots of docks that have USB C at the host end. But that's the wrong way around, I want USB C at the client end, and either USB 3 (type B) or Thunderbolt to connect to the iMac. Has anyone found or can recommend a suitable device?
