Apple Seeds Fourth macOS Monterey 12.3 Beta to Developers [Update: Public Beta Available]

Apple today seeded the fourth beta of an upcoming macOS macOS Monterey 12.3 update to developers for testing purposes, with the new software coming a week after the release of the third macOS Monterey 12.3 beta.

macOS Monterey on MBP Feature
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.

macOS Monterey 12.3 is a major update that introduces Universal Control, a feature that Apple first teased at WWDC and then delayed for several months. ‌Universal Control‌ is designed to allow you to use a single mouse/trackpad and keyboard across multiple Macs and iPads (with iPads running iPadOS 15.4).

After updating your devices to macOS 12.3 and iPadOS 15.4, ‌Universal Control‌ works automatically, allowing your Mac's cursor and keyboard to work on the iPad and vice versa. It's simple and intuitive to use.

macOS Monterey 12.3 adds support for updating the AirPods firmware when the earbuds are connected to a Mac, plus it deprecates kernel extensions used by Dropbox and Microsoft OneDrive, and it eliminates Python 2, with Apple instructing developers to use an alternative scripting language like Python 3 going forward.

There are also new emoji characters, including melting face, biting lip, heart hands, bubbles, beans, face with diagonal mouth, palm up hand, eggs, troll, low battery, coral, lotus, and more.

I've been using macOS/X since Panther.
It's always felt ultra compressed - perfect in form.

I've been aware of sloppy stuff since Catalina.

For example, you can see your trusted devices on iCloud.com and it lists all devices and their Apple Pay cards. On id.apple.com, the cards are missing from the Macs, not from the iDevices. On System Preferences, the same.


It's getting messy, even look at this stylistic disparity in the same config Window in macOS:







* Want / Wish
* a 30 day period / 30 days to




This might seem minor, and it is, but this is the type of slop that's been slowly creeping in.
