How to Use a Projector Wirelessly With a MacBook

By Shawn Farner

Projectors are versatile tools in office settings. If you want to use a MacBook with a projector wirelessly, you can do so by utilizing Apple's AirPlay feature. You'll need to connect an Apple TV device to your projector via the projector's HDMI input.

Connect your Apple TV to your projector. Plug one end of an HDMI cable into the HDMI port on the Apple TV device and the other end into the HDMI port on your projector.

Plug the power cable into the Apple TV and then connect the cable to a nearby electrical outlet. Press the center button on the Apple TV remote to wake the device, which will automatically enter into configuration mode on first use. If you haven't already, turn on your projector.

Select a language for your Apple TV and then select "Wireless Network" as the network type on the network setup screen. When prompted, enter your wireless network's password. If you've already used your Apple TV before and need to set up the wireless network, use the remote to select the "Settings" app, open the "General" page and then choose the "Network" option. Select "Configure Network" to set up a new wireless network.

Open the Web page, application or slideshow presentation you wish to display on your MacBook.

Click on the AirPlay icon in the top menu and then click "Apple TV." This mirrors your MacBook display to the projector. To turn off AirPlay mirroring when you're finished using it, click the AirPlay icon and then click "Turn Off AirPlay Mirroring."

Items you will need

  • Apple TV

  • HDMI cable


The AirPlay mirroring feature requires Mac OS X Mountain Lion or newer.
