Sidecar is an Apple feature that lets you use your iPad as a second screen for your Mac. Instead of being limited to your Mac's built-in display, you can move windows and apps onto your iPad screen — giving you more room to work.
This is useful for: - Keeping reference material (a PDF, a website, notes) on the iPad while working on the Mac - Using drawing apps with Apple Pencil on the iPad while viewing the results on your Mac - Getting more screen space without buying an external monitor
Sidecar works wirelessly over Wi-Fi or wired with a USB cable (USB cable is more reliable and does not drain the iPad battery as fast).
You can use Sidecar in two modes: - **Extended display**: The iPad adds more screen space to your Mac. Different things can show on each screen. - **Mirror display**: The iPad shows exactly the same thing as your Mac.
The iPad's touch screen also works as a pointing device when in Sidecar mode — you can tap on the iPad to click things in macOS. And if you have an Apple Pencil, you can draw on the iPad and have it appear in Mac apps.
Requirements: iPad with iPadOS 13 or later (most iPads from 2014 onward), Mac running macOS Catalina or later, both signed into the same Apple ID.
