If you need to connect an older device that requires i.LINK or FireWire connections to a computer, you either want an old computer with the correct port (IEEE 1394) or an adapter. The Apple Thunderbolt to FireWire Adapter will allow Mac owners to transfer data between their modern computers and aged hardware. Stick the Thunderbolt end into your compatible Mac and the FireWire 800 end into the external device. The adapter supplies up to 7W for peripherals and works on OS X v10.7.4 or later. If you are connecting an old video camera to back up taped footage, use Apple's iMovie software to record as you press Play and let the tapes run.
