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

What's New in Version 2.0

• Add up to 4 displays simultaneously (with the Mac host only for now; Windows support is coming soon. Must be running Air Display 2 host software and Air Display 2 on the extra screens)

• Optimized performance and better energy usage

• Additional display resolution support

Can’t you at least tell what is also required to run on iOS?

Bought this pricey app without being told I need to run iOS 6 to install Air Display 2 on my iPad first generation.

Wasted $20.

More trouble than it’s worth.

Mirroring displays is one of the most useful tools available out there today. Great technology that can seriously enhance productivity. Unfortunately this application fails on most levels. Not only is it too slow to even be worth having two screens, the second display is extremely choppy and nearly impossibly to scroll effectively.

Don’t get too excited about having one display showing a video of some kind while you are working or writing on the other screen because it fails at that too. Displaying videos is always completely out of sync. You could disconnect one display temporarily but than when you reconnect to air display it requires adjustments to get it back to the way you want.

The developers do a good job buttering this app up but you are much better trying to spend the additional cash to get a more effective dual display connection.

If you were wondering if the quality of computers matters, it doesn’t. I am using a brand new 2.7 Ghz iMac with a 2.3 ghz macbook pro. Two exteremely expensive computers. This application is nothing but a waste of time.
