Following last week’s release of the first public beta of the next macOS Monterey 12.3 update, Apple has introduced the second beta of the new software to its public beta testing group.
After downloading the appropriate profile from Apple’s beta software website, public beta testers may download the macOS 12.3 Monterey update from the Software Update section of the System Preferences app.
Mac OS Monterey 12.3 introduces a new feature called “Universal Operate,” which lets you control several Macs and iPads with a single mouse/trackpad and keyboard. If you have a MacBook Pro and an iPad Pro, you can use the trackpad and keyboard on the MacBook Pro to operate both devices, or you can use an iPad keyboard.
Universal Control on the iPad requires iPadOS 15.4, and after the upgrades have been deployed on your devices, the functionality is activated.
Also included in macOS Monterey are new Emoji 14 characters including melting face, a bitten lip, heart hands, and more, as well as support for upgrading AirPods via the Mac. There is no official update interface, but when connected to a Mac, your AirPods may get firmware upgrades over-the-air, much like an iPhone.
In addition, there are a few adjustments beneath the hood. After Python 2’s support was halted in January 2020, Apple is removing it from macOS with macOS 12.3, mandating upgrades to Dropbox and OneDrive’s kernel extensions.
