Until the arrival of macOS Catalina, the only way to be able to mirror the screen of the Mac on the iPad, was with third-party applications. But everything changed with Apple's Sidecar. Bad news for apps like Duet Air?
However the company responsible for one of the best applications, in my opinion, has evolved and has managed to overcome the obstacle that the Sidecar function represented for them. It has saved him and in what way.
Duet Air now duplicates the screen of two Macs or two PCs
Duet Air has been updated and has declared war on the Sidecar function, introduced by Apple through macOS Catalina, which as you know allows you to duplicate the screen of your Mac on an iPad.
However this Apple feature, not valid on all Macs. Those responsible for the creation of Duet Air, they could have continued to subsist with those users who cannot enjoy the functionality from Apple. But not, have decided to evolve, for the good of mortals.
Hereinafter with the application you can duplicate the screen of your Mac and a second Mac or PC. So that second computer can serve as a second wireless screen or mirror screen.
But that is not all, the creators have ensured that they will continue to improve the application and that throughout 2020, we will see new very useful functions and as always with minimal latency.
Remember that in addition to duplicating that screen, Duet Air also allows you to connect via remote desktop to devices that are on the other side of the world.
You could say that Sidecar has not finished with the application but that It has given you wings to improve and innovate. Hopefully they deliver on the promise and that next year we will see more and better additional features.
