How to make your Mac and iPad work together at the same time

“My Apple life is one of privilege,” Kate MacKenzie writes for PixoBebo. “I have a 27-inch iMac on my desk at work. I have a 13-inch MacBook Pro for travel. And I have an iPad Air 2 for, well, just because. The latter two travel with me and each has a specific purpose but there is a way they can work together, side-by-side.”

“All you need is a simple utility on your Mac and iPad and the iPad can become a second screen for the Mac,” MacKenzie writes. “Think about that for a moment. Many MacBook users have a larger display on their desk in the office or at home. And many of us also have an iPad Air. Duet is the affordable utility (free on the Mac, nominally priced for the iPad) which turns the iPad into an extra external display for the Mac.”

“This is one of those nifty utilities which needs to be tried to be appreciated. It works,” MacKenzie writes. “Plug in the iPad to your Mac using a Lightning cable. Run Duet on both iPad and Mac. Like magic, the iPad’s screen becomes an external display for the Mac.”

MacDailyNews Note: Duet is built by ex-Apple engineers, delivering a retina display at 60 frames per second with zero lag. It allows you to interact with OS X like never before, because you can interact with OS X directly with your fingers.

Here are the currently-supported interactions:
• Left click: Tap with one finger to left click anywhere on your iPad display
• Secondary (right) click: Tap with two fingers to use right click

  1. The only problem with Duet is that it doesn’t work with Citrix. The company I work for uses Windows and while Citrix for Mac works fine for remote access, Duet doesn’t support it. Hopefully soon.

  2. This might make the iPad Pro even more compelling for some users, assuming Duet can manage the extra screen real estate. And if the iPad Pro and Apple Pencil can work as a stylus/tablet input for applications on the Mac (ala Wacom), that’s even more interesting.

    I’m still intrigued about the value of using a stylus on an Apple trackpad, but this would go a long way in that direction.

    1. “Nominally priced” makes no grammatical sense since nominal means “in name only.” I think it is supposed to say “minimally priced,” but even there I would say the price is not minimal.
