Every computer I’ve called my own for work or personal use has been a laptop. I love the portability of a laptop. It’s great to do work while lounging in my favorite chair or at a coffee shop (when we could still do that). But it’s really hard for me to put in a full workday hunched over one. To fix that, I’ve found that plugging my laptop to an external monitor on my desk is essential for me to be productive. Now I can’t imagine working without one.
If you’re considering adding another screen to your macOS setup to help fix that laptop hunch or just to add some extra screen real estate, read on. If you have an iPad and a Mac, Apple offers a handy feature called Sidecar that lets you use your iPad as a second display. If you don’t have an iPad, you can connect a separate monitor to your Mac. I’ll walk through how to set up both options in this guide. (We’ll offer advice for how Windows PC users can set up an external monitor in an upcoming article.)
If you want to use macOS Catalina’s Sidecar feature to share your Mac’s screen with your iPad, first make sure you have a Mac and an iPad that both support the feature. You can check Apple’s list of supported devices right here. You’ll also need to be on the right firmware; your Mac will need to be on macOS Catalina and your iPad needs to be on iPadOS 13.0.
