Apple seeded the fifth beta of a future macOS Monterey 12.3 upgrade to developers today for testing reasons, with the new software arriving a week after the fourth macOS Monterey 12.3 beta was released.
Registered developers may access the beta via the Apple Developer Center, and after installing the proper profile, betas will be accessible via the Software Update mechanism in System Preferences.
macOS Monterey 12.3 is a significant update that includes Universal Control, a feature that Apple previously announced at WWDC but then postponed for several months. Universal Control is intended to let you use a single mouse/trackpad and keyboard on numerous Macs and iPads (with iPads running iPadOS 15.4).
After upgrading to macOS 12.3 and iPadOS 15.4, Universal Control will function automatically, allowing your Mac's cursor and keyboard to work on the iPad and vice versa. It's basic and easy to use.
macOS Monterey 12.3 adds support for updating AirPods firmware when the earbuds are connected to a Mac, as well as deprecating kernel extensions used by Dropbox and Microsoft OneDrive, and it removes Python 2, with Apple instructing developers to use an alternative scripting language such as Python 3 in the future.
New emoji characters include melting face, biting lip, heart hands, bubbles, beans, face with diagonal mouth, palm up hand, eggs, troll, low battery, coral, lotus, and more.
