Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter

The Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter lets you connect Thunderbolt and Thunderbolt 2 devices — such as external hard drives and Thunderbolt docks — to any of the Thunderbolt 3 (USB-C)/USB 4 ports on your Mac.

As a bidirectional adapter, it can also connect new Thunderbolt 3 devices to a Mac with a Thunderbolt or Thunderbolt 2 port running macOS Sierra or later.

In addition, it can be used to connect Thunderbolt-enabled displays — such as the Apple Thunderbolt Display and LG Thunderbolt 2 displays — to any of the Thunderbolt 3 (USB-C)/USB 4 ports on your Mac. However, using this adapter with an Apple Thunderbolt Display requires a power source, because the display does not provide power through the adapter.

Note: This adapter does not support DisplayPort displays like the Apple LED Cinema Display, or third-party DisplayPort and Mini DisplayPort displays.
