Use iPad as a second display for your Mac

With Sidecar, you can extend the workspace of your Mac by using iPad as a second display. The extended workspace allows you to do the following:

Use different apps on the different screens.
Use the same app on both screens. For example, you can view your artwork on your Mac screen while you use Apple Pencil and an app’s tools and palettes on iPad.
Mirror the screens so that Mac and iPad display the same content.

Sidecar requires macOS 10.15 or later and iPadOS 13 or later on supported models.
