Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter, Model A1790

Thunderbolt 3 (USB-C)/Thunderbolt 2 adapter

The Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter lets you connect Thunderbolt and Thunderbolt 2 devices (like external hard drives and Thunderbolt docks) to any Thunderbolt 3 (USB-C) port on your MacBook Pro.

This bidirectional adapter also allows you to connect Thunderbolt 3 devices to Thunderbolt or Thunderbolt 2 ports on a Mac running macOS Sierra.

Additionally, it allows you to connect monitors with Thunderbolt ports, such as the Apple Thunderbolt Monitor or LG Thunderbolt 2 monitors, to any of the Thunderbolt 3 (USB-C) ports on your MacBook Pro. However, connecting an Apple Thunderbolt monitor through this adapter requires a power source because the adapter does not provide power to the monitor.

Note. This adapter does not support DisplayPort monitors such as the Apple LED Cinema Monitor or third-party DisplayPort and Mini DisplayPort monitors.
