Apple Seeds Third macOS Monterey 12.3 Beta to Developers

by

Apple today seeded the third 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 second 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. There is also a macOS 11.6.5 update for those still running macOS Big Sur.

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.

maOS 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.

Really hope this is the release with major issues addressed and feature complete. I’d like to upgrade, just for universal control and the latest privacy and security features, but Apple’s poor software quality demands precaution before upgrading.
So your not really participating in beta testing, right? Just making comments.

Are you complaining, I can't tell. It makes sense to have administrator status for performing an administrator function. I like a bad guy have administrator status in my main login, and got no login prompt before downloading. I did need to type a password before install, but that seems fair. I know, I know, I should have separate logins, don't remind me
Its a legit observation.

For many 12.0, 12.0.1, 12.1, 12.2 Monterey betas in the past it was at the end of the install. Download, preparation, prompted Admin credential then it installs.

12.3 Beta 2 and this Beta 3 have the Admin credential event now occurring before the whole installation process. Its functional better because you don't have to wait until the end of preparation to return to do that.

Improve safari already! It's not like you don't have the money, Apple. Make it the best browser for the Mac, not just a nice to look at browser that misbehaves all the time

Good deal want to see how the third beta does against some issues.

macOS 12.3 beta 3 (21E5212f). Once again it starts by asking for admin password before downloading. M1 download is 2.92 GB.
