Thunderbolt technology supports fast data transfers with two independent channels of 10 Gbps each. And Thunderbolt 2 technology can bond the two channels for a super-fast 20 Gbps. Use this cable to connect Thunderbolt-enabled devices to the Thunderbolt or Thunderbolt 2 port on your Mac. The Apple Thunderbolt Cable lets you connect two Thunderbolt-equipped Mac computers in target disk mode, network two Mac computers with OS X Mavericks or use your iMac as a display for a MacBook Pro or MacBook Air.
