The iPadOS 15.4 and macOS Monterey 12.3 betas that Apple released today introduce support for Universal Control, the long-awaited feature that's designed to allow multiple Macs and iPads to be controlled with a single mouse and keyboard.
There are Universal Control settings available on both the Mac and the iPad, and the feature is enabled by default after updating to the new betas. On the Mac, the settings can be found under Displays > Advanced, and on the iPad, the AirPlay & Handoff section under General has a new "Cursor and Keyboard (Beta)" option.
With Universal Control, you can use the same cursor and keyboard on any nearby Mac or iPad that's signed into your iCloud account. So, for example, if you have a MacBook and an iPad next to it, your MacBook's trackpad and keyboard can be used right on the iPad.
Apple introduced Universal Control in June at the Worldwide Developers Conference and initially said that it would be introduced this fall, but the company was not able to meet that deadline and ultimately delayed the launch.
In December, Apple updated its macOS Monterey feature page with a "spring 2022" release date for Universal Control, which is aligned with when we are expecting to see iPadOS 15.4 and macOS Monterey 12.3 launch.
