Apple Seeds First Beta of macOS Monterey 12.3 to Developers
Apple today seeded the first beta of an upcoming macOS Monterey 12.3 update to developers for testing purposes, with the new software coming just a day after the release of macOS Monterey 12.2.

Registered developers can download the beta through the Apple Developer Center and after the appropriate profile is installed, betas will be available through the Software Update mechanism in System Preferences.
In the release notes for the update, Apple confirms that it has deprecated kernel extensions used by Dropbox and Microsoft OneDrive and notes that both cloud storage services have replacements for the functionality currently in beta. The update also adds new emojis and support for Universal Control.
Universal Control is designed to allow a single mouse and trackpad to be used with multiple Macs and iPads, and Apple has said it will be launching this spring.
