Apple has released macOS Monterey 12.3 for Mac users running the Monterey operating system.
Notably, macOS Monterey 12.3 includes support for Universal Control, the long-awaited feature that lets a single mouse and keyboard control multiple Macs and iPads. To use Universal Control with macOS Monterey and iPad, all connected devices must be running macOS 12.3 or later, and iPadOS 15.4 or later. The feature is enabled by default.
MacOS Monterey 12.3 also includes other small improvements, dozens of new Emoji icons, and bug fixes, making it recommended for all Mac users running the macOS Monterey operating system. Note that macOS Monterey 12.3 removes Python 2 from macOS, so you’ll want to make Python 3 the default or find an alternate solution if you’re relying on python.
Separately, Apple released iPadOS 15.4 for iPad, iOS 15.4 for iPhone, tvOS 15.4 for Apple TV, and watchOS 8.5 for Apple Watch.
How to Download MacOS Monterey 12.3 Update
Always back up the Mac with Time Machine before starting any system software updates.

Mac users who are not yet running Monterey but are instead running an older version of system software like Big Sur or Catalina will find a security update and Safari updates available.
macOS Big Sur 11.6.5 will be available for macOS Big Sur users, while Security Update 2022-003 Catalina will show up for macOS Catalina users.

How do I enable universal control?
On macOS, Universal Control can be enabled by going to Apple Menu > System Preferences > Displays > Universal Control > and checking the box for “Allow your cursor and keyboard to move between any nearby Macs or iPads”.
Universal Control is enabled by default on the iPad, but the settings toggle is in Settings > General > Airplay & Handoff > “Cursor & Keyboard (Beta)”.
Remember that Universal Control requires all eligible devices to be running macOS 12.3 or later, or iPadOS 15.4 or later.
Assuming all devices are running the latest versions of system software, you’ll find the Universal Control settings on the Mac in System Preferences > Displays, where you can adjust feature settings, as well as screen orientation.
