Apple's new computers have a new type of port called USB-C*. These ports are faster and more versatile than their predecessors, however, in production setups, a computer with a different type of port can mean you suddenly can't plug in the same adapter that you have used in the past.
Standard Video Outputs (HDMI, VGA, DVI)
If you are going to a standard video output from the computer (such as an HDMI or VGA cable), then our recommendation would be to purchase a USB-C adapter for your setup. For example, if you are running HDMI to your audience screen, you can pick up any USB-C to HDMI adapter and it ought to output like normal. These adapters are widely available online as well as in your local computer store.
DualHead2Go and TripleHead2Go
For our users that are using more specialized devices such as a DualHead2Go or a TripleHead2Go you may need a different type of adapter. If your device takes in a standard type (such as VGA) then you would need a simple USB-C to VGA adapter, however many of these devices run off of DisplayPort inputs, which is a less common cable type. The good news is that USB-C ports on Macs are backwards compatible with the DisplayPort standard, so if your device requires a DisplayPort input then we would suggest a USB-C to DisplayPort cable such as this one**.
Closing
USB-C is designed to be as backwards compatible as possible, so generally speaking you should be able to buy a USB-C adapter for whatever your video needs are. As a general recommendation we recommend buying name-brand devices as they will often last longer than knock-off brands, so in a production environment it is often recommended to spend a few extra dollars to make sure that your device will work a long time.
*Technically on a Mac they are called Thunderbolt 3 ports, but for the purposes of this article, we will refer to them by their more common "USB-C" name.
