Connect your Thunderbolt-equipped Mac to a FireWire device with the Apple Thunderbolt to FireWire Adapter. Small and compact, it connects to the Thunderbolt (also works with Thunderbolt 2, but will be limited to Thunderbolt speeds) port on your Mac computer, giving you a FireWire 800 port that supplies up to 7W for bus-powered peripherals like hard drives and audio devices.
