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 wirelessly connect to it from the free host app on your main Mac, to instantly expand its screen real estate. You can also connect with Ethernet, Thunderbolt, or USB-C.

IMPORTANT: This is NOT the free Air Display host software that you need on your main computer. You can download 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


You’ll need the free Air Display host app (from installed on your main Mac, 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

• Mac client app: iOS 6 and above

Don't want a nickname 3847383 ,

It works, but very slow and laggy.

I'm using air display to connect a new MBP to a new 21" retina imac as an external display.

It does not use the whole imac display, but instad crates a window with fixed aspect ratio. I am using the external for text only, with no video, etc. It works but is very slow. The mouse hops around with 200ms to 500 ms latency. The image is also not grisp. It looks like it is being interpolated or somethig. Definithely not displaying pixel-for-pixel.

Overall, yes it functions, and it allows me to do my work, but I am dissapointed, and would not buy the software again.

Waste of money!!!!

Bought it to try and mirror my mac with Apple TV. In theory in worked but it's so slow displaying to my ipad it's unusable. It costs $20 for the app on your mac but they don't tell you you need to download the app for your iPad as well, which costs $10. Then I ran into an issue where my mac's login screen would only display in 1024X768. After looking into found out that others had experienced the same issue and fixed it by uninstalling Air Dsplay. Don't buy it, I want my money back.

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.
