You can use Sidecar wired or wirelessly, but if you want to switch between them, you have to disconnect and re-connect using the AirPlay menu. You can mirror your Mac's display or extend it, show or hide the Sidebar and Touch Bar that appear on the iPad, or disconnect your tablet. The icon will change, and clicking the menu again will offer you a number of options. You'll also need to be logged in to the same Apple ID on both devices.Ĭlick the AirPlay button in your Mac's menu bar and select your iPad from the list.

To connect your iPad as a display, either connect your iPad to your Mac over USB, or-to do it wirelessly-ensure Bluetooth, Wi-Fi, and Handoff are turned on. (If your devices are older than that, skip down to the next section.)

So if you have a Mac and an iPad from the past five or so years, you'll want to try it first. Sidecar is arguably the best option for turning your iPad into a second display.
