Or perhaps you want to keep your eye on a specific app during the day putting it on its own display lets you view it at a glance. You may want to do this for a number of reasons, such as when you need to view two windows at the same time, but are working on a laptop, where you don’t have enough screen real estate. Mirroring the display is of limited use, but where Sidecar becomes really practical is when you move a single window to your iPad. (I discuss the buttons in the iPad sidebar below.) Move windows to Sidecar To return to your normal display, click the AirPlay icon and choose Disconnect, or tap the Disconnect button in the sidebar on the iPad. You can hand someone your iPad, so they can be, for example, across a desk or table from you, and when in this mode, you can switch apps, type, and edit files, as normal the only difference is the display: it changes to the aspect ratio and resolution of the iPad.

This is a good way to show someone else something on your Macs, such as design drafts, photos, or videos. If you do this, you’ll see the same thing on your iPad as on your Mac. The Mac will send the frontmost window to that iPad.įrom the AirPlay menu, you can also choose to mirror the display. If you have the AirPlay icon in your menu bar, you can click it and choose an iPad. There are a couple of ways you can use Sidecar. This limits your flexibility, since you can’t move the iPad very far, but if you want to use Sidecar all day, with, for example, a specific app always on your iPad, this allows it to have enough power. You can also use Sidecar with a USB connection just use the cable that came with your iPad to connect it to your Mac. Bluetooth and Wi-Fi must be turned on, along with Handoff. Your Mac and iPad must be signed into iCloud with the same Apple ID, using two-factor authentication, and you should be within about 10 meters or 30 ft this is the range of Bluetooth, which is used for discovery and to establish connections. To use Sidecar, you need a Mac from 2016 or later (one exception is the late-2017 5K Retina iMac), and an iPad Pro (any model), iPad (6th generation or later), iPad mini (5th generation or later), or iPad Air (3rd generation or later). In this article, I’ll show you how you can use Sidecar to extend your Mac’s display. And if you work on a laptop, having that additional screen space for occasional or even regular usage can make your work a lot smoother. This is practical if you want to work on a document on your iPad using the Apple Pencil, or if you want to be able to show something from your Mac to a colleague or client without them needing to look over your shoulder.

One of the more useful features in macOS Catalina is Sidecar, which allows you to use your iPad as a second display for your Mac.
