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 and 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.
