Use iPad as a second display for your Mac

With Sidecar, you can use your iPad as a display that extends or mirrors your Mac desktop.

Get ready

  • Before continuing, make sure your Mac and iPad meet the Sidecar system requirements, including each device being signed in with the same Apple ID.
  • You can use Sidecar wirelessly, but to keep your iPad charged during use, connect it directly to your Mac with the USB charging cable that came with your iPad.

If you want your keyboard, mouse or trackpad to control your Mac and iPad, with your iPad displaying its own Home Screen and apps rather than the desktop and apps shown on your Mac, use Universal Control instead.

 


Move a Mac window to your iPad

Move your pointer over the full-screen button  of a window on your Mac, then choose the option to move that window to your iPad.

You can repeat this step for other Mac windows, or simply drag other Mac windows to and from your iPad. To move a window back to your Mac, you can also move your pointer over the full-screen button  and choose Move Window Back to Mac.

If you want your iPad to mirror your Mac screen instead of extending its desktop:

  • In macOS Monterey, choose a mirroring option from the Screen Mirroring menu  in the menu bar.1
  • In macOS Big Sur, choose a mirroring option from the Display menu in Control Centre or the menu bar.
  • In macOS Catalina, choose a mirroring option from the AirPlay menu ( or ) in the menu bar.2


The sidebar puts commonly used Mac controls on the side of your iPad screen. It includes Command, Shift and other modifier keys, so you can choose essential commands with your finger or Apple Pencil instead of a keyboard.

Use gestures for scrolling and other actions

These Multi-Touch gestures are particularly useful when using your iPad as a display.

  • Scroll: swipe with two fingers.
  • Copy: pinch in with three fingers.
  • Cut: pinch in with three fingers twice.
  • Paste: pinch out with three fingers.
  • Undo: swipe left with three fingers or double-tap with three fingers.
  • Redo: swipe right with three fingers.


Use Apple Pencil

To point, click, select and perform tasks such as drawing, editing photos and manipulating objects on your iPad while it's extending or mirroring your Mac display, you can use your Apple Pencil instead of the mouse or trackpad connected to your Mac. You can also use it to write, sketch and mark up documents while seeing the updates live on your Mac.

Sidecar also supports double-tap, which you can turn on in System Preferences. Double-tap enables apps that support this feature to perform custom actions when you double-tap the side of your Apple Pencil (2nd generation).


Use the Touch Bar

Many apps on Mac have Touch Bar controls that make common actions even easier. With Sidecar, you get a Touch Bar on your iPad screen even if your Mac doesn't have a Touch Bar. Tap its controls with either your finger or Apple Pencil. If the Touch Bar isn't appearing when using an app that offers Touch Bar controls, choose Apple menu  > System Preferences, click Mission Control, then make sure "Displays have separate Spaces" is selected.


Use a keyboard, mouse or trackpad

During your session, you can type using the keyboard connected to your Mac, or you can use a keyboard connected to your iPad, such as the Smart Keyboard or Magic Keyboard for iPad. To point, click or select with a mouse or trackpad, use the mouse or trackpad connected to your Mac or use an Apple Pencil on your iPad.


Use iPad apps

While using your iPad as a display, you can switch to an iPad app, then interact with that app on your iPad as you normally would. This will suspend your session until you switch back to the Sidecar app, which only appears on your iPad Home Screen while using Sidecar.
