The Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter lets you connect Thunderbolt and Thunderbolt 2 devices — external hard drives and Thunderbolt displays, for example — to any of the Thunderbolt 3 (USB-C) ports on your MacBook Pro.
Enjoy your music library and favorite playlists anywhere with a single cable solution that connects iPhones to car stereos, home speaker systems or portable speakers.
