A Thunderbolt adapter allows Apple Thunderbolt, a revolutionary I/O technology, to operate on the adapter’s interface. This helps connected devices achieve high-resolution displays and transfer data in high speeds. These two properties are exchanged through a single, compact port connecting two or more Apple devices.
Some of the devices compatible with Thunderbolt adapters include MacBook Pro with Retina display computer models and the Mac Pro released in late 2013. Other devices include MacBook Pro, MacBook Air, Mac mini and iMac. These devices are only compatible if they were released in June 2011 or after. In addition, Thunderbolt adapters require these computers to be installed with OS X Lion v10.7.4 or later. For thunderbolt-equipped Macs released before June 2012, another installation is required, which is the Thunderbolt Software Update 1.2.1.
