Use your iPad as a second display for your Mac

You can extend the workspace of your Mac by using your iPad as a second display with the Sidecar feature. The extended workspace allows you to use different apps on the different screens, or to use the same app across both screens, but control different aspects of it. For example, when you use the same app on both screens, you can view your artwork on your Mac while you use ApplePencil and an apps tools and palettes on iPad.

[A MacBook Air and an iPad sitting side by side. Both screens display an article covered in scribbled red edits, such as crossed-out sentences, arrows and added words. The iPad also has Mark Up controls at the bottom of the screen.]

Before you begin

Make sure of the following:

Both devices have Wi-Fi, Bluetooth and Handoff turned on.
Youre signed in to the same Apple Account on both devices.
Your devices are within 10 metres (30 feet) of each other.
Both devices meet minimum system requirements for Sidecar.

Set up Sidecar

On your Mac, go to the System Settings app [].
Click Displays [] in the sidebar. (You may need to scroll down.)
Open Displays settings for me
You can also connect your Mac and iPad using a USB cable. You can use the USB cable that came with your iPad or another cable that matches the ports on your Mac and iPad.
Click [the Add Display menu] on the right, then choose your iPad.
To change Sidecar options (for example, to extend or mirror your Mac display), choose your iPad in Displays, then choose from the available options in the Use as pop-up menu.
You can also adjust the arrangement of your Mac and iPad displays. Click Arrange, then drag your displays into a new position.
Tip: You can use Control Centre to set up Sidecar. Click [the Control Centre status menu] in the menu bar, click Screen Mirroring, then choose your iPad. You can adjust some Display settings here, or click Display Settings for more options.
[The Displays settings pane on Mac showing options for setting up Sidecar.]

Use Sidecar with your Mac or iPad

Do any of the following:

Move windows between Mac and iPad: Drag a window to the edge of the screen until the pointer appears on the other device. Or while using an app, choose Window > Move to.
Use the sidebar on iPad: With your finger or Apple Pencil, tap icons in the sidebar to show [] or hide [] the menu bar, show [] or hide [] the Dock, or show the onscreen keyboard []. Or tap one or more modifier keys, such as Control [], to use keyboard shortcuts.
Use the Touch Bar on iPad: With your finger or Apple Pencil, tap any button in the Touch Bar. The buttons available vary depending on the app or task.
Use Apple Pencil on iPad: With your Apple Pencil, tap to select items such as menu commands, tickboxes or files. If your Apple Pencil supports it (and you selected the option in Displays settings), you can double-tap the lower section of your Apple Pencil to switch drawing tools in some apps. See the Apple Support article If you cant pair Apple Pencil with your iPad.
Use gestures on iPad: Use basic gestures, such as tap, swipe, scroll and zoom, as well as gestures for entering and editing text. See the Learn basic gestures to interact with iPad.
On iPad, switch between the Mac desktop and the iPad Home Screen: To show the Home Screen, swipe up from the bottom edge of your iPad. To return to the Mac desktop, swipe up, then tap [the Continuity icon].

Turn off Sidecar

When youre ready to stop using your iPad as a second display for your Mac, do one of the following:

On a Mac: Click [the Control Centre status menu] in the menu bar, click Screen Mirroring, then deselect your iPad from the list below Mirror or Extend to.
On an iPad: Tap [the Disconnect icon] at the bottom of the sidebar.
