The Universal Control is one of the much-anticipated features of macOS Monterey and iPadOS 15. This feature was unveiled at Apple’s 2021 Worldwide Developers Conference (WWDC 2021).
You can use a single mouse and keyboard to control your Mac and iPad devices, making it simple to switch between them and greatly improving your productivity.
Unfortunately, this feature was never made available to beta users, but a developer has discovered a way to enable Universal Control partially in macOS Monterey beta 5.
Enable Universal Control
The feature can be enabled by editing some internal operating system files, similar to how users could revert to the old Safari in macOS Monterey’s first beta. The procedure is not difficult but modifying system files can always lead to other problems, so be aware of this before you begin.
Developer Zhuowei Zhang has shared the codes required to enable Universal Control on a supported Mac on GitHub. To make things easier, you can simply download the file from GitHub and move it to the appropriate folder on your Mac. This method has only been tested with macOS Monterey beta 5 and may not work with future betas.
