Apple in macOS Catalina introduced a new Sidecar feature that lets the iPad be used as a secondary display for a Mac, something that third-party companies have been doing for some time with products like Duet Display and Luna Display.

With ‌Sidecar‌ now available for the ‌iPad‌, Duet has adapted and introduced new functionality that's not available with ‌Sidecar‌ - namely using an additional Mac or PC as a secondary display.

As of today, Duet Air, the software that turns the ‌iPad‌ into a secondary display for a Mac, also works with a second Mac or PC.

That means if you have an extra MacBook or PC, you can use Duet Air to turn it into a wireless second display or a mirrored display for your main Mac. This is functionality that's not available with Apple's ‌Sidecar‌ implementation.

Duet Air also allows iOS devices, Macs, or PCs to remote desktop into other devices from anywhere in the world, and Duet says that the update works with "minimal latency."

Over the course of the next year, Duet has pledged to continue improving its algorithms and customizability, and there are a long list of new features in the works that will make Duet Air more compelling in 2020.

We appreciate the kind words!

Luckily, we worked hard to add support for Windows (half of iPad users), Android (most mobile users), and desktop to desktop. We also support over a hundred million iPads & Macs even Apple does not, but we are finding a lot of people choosing us even on new hardware where Sidecar exists.

We are focused on professional customers that use the product every day, and they often prefer the additional features & customization we offer.

I wish these guys lots of luck. It’s not easy pivoting to something new like that after Apple basically tries to put you out of business. These seem like genuinely useful new features.

Hey man,

if you’re responsible for Duet, I just wanted to stop a minute and tell you guys you do great work. Even whenever a company as big as Apple tried to offer a similar feature, you found a way to improve Duet and it’s feature set. Being a developer of original products in this era can be quite PITA, but you guys constantly bring your A game. Keep up the good work, stay golden, and keep bringing great new features.
I did create Duet but am now just a small part of the amazing team that delivers those features and is responsible for the current success. Thanks for the support and kind words...can't wait to show you what we will deliver next year.


Does this mean I can use an older iMac as a display powered by my newer MacBook pro?
Yes it does...even if you have a PC :)

Mmmm.. I have been able do this for years with 5KPlayer (free) or AirServer (one time fee of 7.99 to 19.99 depending on license).
Both work great, no need to pay for a subscription forever.
Neither of these support remote desktop, are as cross-platform compatible, or are very fast (AirPlay is notoriously buggy and slow) among other features. I also think the main purpose is using your Mac as a mirrored display for your iOS device? Not sure why you keep writing this in the comments of every press article about Duet.
