Air Display for Mac lets you use a spare Mac’s screen as an extra display for your main computer. Launch this app on your spare Mac, then wirelessly connect to it from the free host app you’ll install on your main Mac or PC to instantly expand its screen real estate.

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


• 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
• Choose to run 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 over Ethernet
• Extremely responsive performance
• Mouse responsiveness indistinguishable from using a wired mouse


You’ll need the free Air Display host app (from installed on your main computer, and this Air Display client app running on the Mac you want to use as an extra screen.

• Purchase this app on the Mac you want to use as your second display
• On your main computer, go to and install the free host app
• Launch Air Display on your "second display" Mac and it will help you finish the setup

If you want to use your iPad or other mobile 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 from on your main computer).


• Both computers must be on the same Wi-Fi network, either via Wi-Fi or Ethernet
• Mac client app: iOS 6 and above
• Mac OS X host: 10.7 and above
• Windows host: 7 or 8 (32 or 64-bit); Windows 7 Starter Edition and Windows Vista are not supported; laptops with Nvidia's Optimus dual-graphics switching are only compatible when you disable the Optimus feature
• Connection to multiple Air Display clients is Mac only, but we're working on Windows even now
