Looking to share your MacBook Air screen on a larger display?

You can connect your MacBook Air to a projector using cables like HDMI and USB-C adapters or go wireless.

Let’s explore the straightforward steps for this setup!

Two Ways to Connect Your MacBook to a Projector

The following are two veritable methods to connect your MacBook to a projector.

Using USB-C to HDMI Adapter or Mini DisplayPort to HDMI Adapter

Note that MacBook Airs do not have an HDMI port since maybe the chassis is too thin or Apple doesn’t deem it necessary for the model. You’ll, therefore, have to employ workarounds.

If the device has a USB-C port, which it likely should, use a USB-C to HDMI adapter. If your MacBook Air has a Mini DisplayPort, use a Mini DisplayPort to HDMI adapter.
