What hardware do I need? » Mac Video Adapters
This are adapters for a Macbook, the white kind that you see in these picks. Neither one is an actual Apple product which saves you about $15 each. One has a VGA end and one has a DVI end. You will also see the one I use the most in another picture with an HDMI end. Those three ends allow you to attach to just about any TV or projector. You don’t have to have all three as long as you check the TV/Projectors at the location to make sure you have the right one. Best Buy, Apple, Staples all have them.
