Apple's all-new Sidecar feature, coming in macOS Catalina this fall, allows users to expand their Mac desktop using their iPad as another display or as a high-precision input device across creative Mac apps.
John Voorhees for MacStories:
The core experience of using Sidecar is fantastic. Part of the reason is that running an iPad as another monitor for a Mac with Sidecar is immediately familiar to anyone who has ever used multiple monitors. The extra screen property, portability and functionality are also part of the appeal. Of course there are differences that I get into, but Sidecar is so close to a traditional dual screen setup that I expect it will be a natural extension of the way many people work on the Mac.
Apple made it clear when they introduced Catalyst in 2018 at WWDC that it does not replace macOS with iOS. Some tasks are better suited for a Mac than an iPad and vice versa. Sidecar recognizes these differences by letting an iPad become an extension of the Mac for tasks best suited to it. At the same time, however, Sidecar utilizes the functionality not available on Mac, such as Apple Pencil. Combined with the ability to seamlessly switch between using Mac apps running in Sidecar and original iPadOS apps, the most effective way is to have a touch-screen Mac.
MacDailyNews Take: Even in beta, Sidecar is an exciting look at the future of Mac and iPad symbiosis.
