Apple introduced a new feature called Sidecar in macOS Catalina, with this iPad can be used as a second display for your Mac either to extend or mirror the same screen. Once extended, you can access and control your Mac with iPad; this means now you can use markup, Apple pencil, and lots of other iPad friendly features with your Mac apps.
Extending display isn’t new to Apple users, lots of you may be using some third-party software such as Luna, or Duet Display for this purpose. But as this is a built-in feature in macOS Catalina, you don’t need to worry about hardware specifications. Sidecar works either wirelessly or by connecting your iPad and Mac with USB-C or Lightning cable.
Apple didn’t officially specify any supported devices, but we’ve tested this on iPad Pro running iPadOS and MacBook Pro running macOS Catalina 10.15, and it works perfectly fine. However, Sidecar supports iMac 27″ (Late 2015) or newer, MacBook Pro (2016) or newer model, Mac Mini (2018), Mac Pro (2019), MacBook Air (2018), MacBook (Early 2016 or newer). Before getting started, make sure your iPad is on iPadOS and Mac is running macOS Catalina. Follow along and I’ll walk you through all the steps in detail.
