Thunderbolt 3 (USB-C)-Thunderbolt 2 adapter can connect your Thunderbolt and Thunderbolt 2 connecting devices, such as external hard drives and thunderbolt docks, to any Maced 3 (USB-C) or USB 4 ports.

The converter operates in both directions, so you can use the Thunderbolt 3 connecting devices to connect Thunderbolt or Thunderbolt 2 port, Macos Sierra and newer maces.

It also allows you to connect a Thunderbolt-compatible display, such as Apple Thunderbolt Display or LG Thunderbolt 2, to any Maced 3 (USB-C) or USB 4 ports. If you use it for Apple Thunderbolt Display, you also need to provide an external power source because the display does not supply the display through the converter.

Note: The converter does not support DisplayPort display (such as the Apple LED Cinema or external displayport and mini displayport display). For more information about the Thunderbolt 3 (USB -C) - Thunderbolt 2 converters, you will find more information on Apple's support page.
