Can I connect a Thunderbolt 3 device to a Thunderbolt 2 Mac?

Yes, you can use the Thunderbolt 3 to Thunderbolt 2 adapter from Apple to connect a Thunderbolt 3 device to a Thunderbolt 2 computer. This is currently the only bi-directional adapter. The miminum system requirements for that adapter are macOS Sierra but we recommend using macOS High Sierra or above.

Things to consider:

  1. The Thunderbolt 3 device has to be a self-powered device. Bus-powered devices like the T3-10G are not supported.
  2. Power delivery is not supported. If your Thunderbolt 3 device provides power to your laptop over Thunderbolt, this function will not be available anymore.
  3. The bandwidth will be limited to around 1375 MB/s due to the Thunderbolt 2 interface.
  4. This only works for Thunderbolt 3 devices, not for USB-C devices like the Neutrino U3.1.
  5. The next time you update the OS, make sure the TB3 to TB2 adapter is connected to your computer, so that the firmware of the adapter can be udpated simultaneously.
