The white Apple 1.6' (0.5 m) 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.
Thunderbolt technology supports fast data transfers with two independent channels of 10 Gb/s each. And Thunderbolt 2 technology can bond the two channels for a super fast 20 Gb/s. Use this cable to connect Thunderbolt-enabled devices to the Thunderbolt or Thunderbolt 2 port on your Mac.
