Apple iPadā€™s significant feature is really outstanding. Basically, Sidecar is a feature that allows you to share the Mac screen on the iPad display. We can call it a secondary screen of Mac; it will greatly increase productivity. Across two devices, you can edit your stuff and see the real-time changes on both devices.
Open System Preferences and choose Sidecar. In the window, press Select Device, and select your iPad. Select Sidecar menu on your Mac to choose the iPad's role. Select Use As Separate Display. You can now drag windows between displays. Duet Display, Air Display, and iDisplay are other great options to set up your iPad as a second display. How Sidecar Works . You will need a supported Mac and iPad to use Sidecar. Most Macs made after 2016 with macOS Catalina or later are supported, along with most modern iPad models. The devices also must be signed in with the same Apple ID, use two-factor authentication, and be within 30-feet of each other. On both a Mac and an iPad, sign into either device with the same Apple ID. For the first time connection, plug in an Apple USB to Lightening or USB-C connector between the Mac and the iPad. Authenticate the iPad to communicate with the Mac. Sidecar controls have been moved from System Preferences to the Airplay menu bar.
The Apple Sidecar feature was first announced at Appleā€™s WWDC event, and it is yet to be introduced to Macs and iPads. This capability will be included in an operating system update in the fall of 2019. With the feature, people will be able to use their iPads as secondary displays along with their Mac devices.
Before the final release of macOS 12.3 and iPadOS 15.4, many tried unsuccessfully to use Universal Control alongside Sidecar between Mac and iPad. . 293 390 349 235 149 179 123 294 350
