App Description

Air Display lets you use a spare Mac’s screen as an extra display for your main Mac.

It's easy to use! Just launch this app on your spare Mac, then connect to it from the free host app on your main Mac, to instantly expand its screen real estate. You can connect wirelessly or with a cable.

IMPORTANT: This is NOT the free Air Display host software that you need on your main computer. You can download that at avatron.com/gethost. This is the client app that turns one Mac into a second monitor for another Mac.

–– FEATURES ––

• Drag windows, apps, or control palettes from your main screen to give yourself more room to work
• Use up to 4 devices simultaneously to extend or mirror your computer
• Run either full-screen or in a window
• Either extend your screen to get more room to work or mirror to share your screen with an audience
• Connect via Wi-Fi or with a wired connection (Ethernet, Thunderbolt, or USB-C)

–– INSTALLATION ––

Just install the free Air Display host app (from avatron.com/gethost) on your main Mac, and download this Air Display client app on your second Mac.

• Purchase this app on the Mac you want to use as your second display
• On your main computer, go to avatron.com/gethost and install the free host app
• You can install this app onto multiple Macs, as long as they use the same Apple ID

If you want to use your iPad or other device as your second screen, you do not need to purchase this app. Air Display for iOS is available in the iTunes App Store (and you’ll still need the same free host software on your main computer).

–– COMPATIBILITY ––

• Both computers must be on the same Wi-Fi network, or connected via Ethernet, Thunderbolt, or USB-C
• Mac client app: macOS 10.8 and above
• Mac host: macOS 10.10 and above (not compatible with macOS 10.13.4–10.13.6)
• The Air Display host software is not compatible with Windows
