How to sign documents on your Mac with your iPhone or iPad

This fall, macOS Catalina, iOS 13, and iPadOS 13 will offer greater interoperability between Mac, iPhone, and iPad than ever before, with new features like Sidecar allowing your iPad to serve as a second screen for your Mac. And while Sidecar as a whole seems limited to newer Macs, some features will be available to a larger range of them.

For instance, you will now be able to sign documents on your Mac using your iPhone or iPad. Using the macOS markup features in Quick Look or Preview, you'll be able to add a signature directly from your iPhone or iPad. This is great, especially if you have an iPad from 2018 or later, as they all work with some version of the Apple Pencil, allowing you to create a completely accurate signature for use on your Mac.
