Apple has started to distribute its second beta of macOS Monterey 12.3, with builds now downloadable by developers testing the operating system.

The newest builds can be downloaded via the Apple Developer Center for those enrolled in the test program, or via an over-the-air update on devices running the beta software. Public betas typically arrive within a few days of the developer versions, via the Apple Beta Software Program website.

The first build of macOS Monterey 12.3 became available to developers on January 27. The public beta build arrived one day later, on Jan 28.

The key addition in macOS Monterey is Universal Control, a feature that works with iPadOS 15.4 to enlarge the user's workspace. Under Universal Control, a single keyboard, trackpad, or mouse connected to a Mac can be shared with multiple other nearby Macs or iPads.

Shortly after its release, Apple issued a warning to developers not to install the beta onto a Mac with macOS Catalina and FileVault installed.

AppleInsider, and Apple itself, strongly recommend users don't install the betas on to "mission-critical" or primary devices, as there is the remote possibility of data loss or other issues. Instead, testers should install betas onto secondary or non-essential devices, and to make sure there are sufficient backups of important data before updating.
