Apple Seeds Third Beta of macOS 12 Monterey to Developers

Apple today seeded the third developer beta of macOS Monterey, the newest version of the macOS operating system. The third beta comes nearly three weeks after Apple released the second macOS Monterey beta.

macOS Monterey on MBP Feature
Registered developers can download the beta through the Apple Developer Center and once the appropriate profile is installed, betas will be available through the Software Update mechanism in System Preferences.

As with all new betas, Apple recommends not installing the new macOS update on a primary machine because it is early release software and could have bugs.

macOS Monterey introduces Universal Control, a feature that lets a single mouse, trackpad, and keyboard be used across multiple Mac or iPad devices, plus there's a new AirPlay to Mac feature.

Safari has been redesigned with a new tab bar and support for Tab Groups, and FaceTime has gained spatial audio, a Portrait Mode on M1 Macs, and Voice Isolation for cutting out background noise. There's also a new SharePlay ‌FaceTime‌ feature that lets Apple users watch TV, listen to music, and share their screens with one another.

Shared With You, a separate feature, keeps track of the music, links, podcasts, news, and photos that people are sent in Messages, highlighting it in the relevant apps. Notes has a new Quick Note feature for jotting down thoughts, and collaboration is easier with mentions and an Activity View.

The Shortcuts app from iOS is now available on the Mac, and Focus helps people stay on task by cutting out background distractions. There's an updated Maps app with a whole slew of new features, and with Live Text, Macs can now detect text in photos or provide details on animals, art, landmarks, plants, and more in images.

Mail Privacy Protection hides IP and prevents tracking through invisible pixels, and iCloud Private Relay keeps Safari browsing protected. There are many other new features in macOS Monterey, with a full rundown available in our macOS Monterey roundup.

They changed Safari! They now have an option to "Show Separate Tab Bar" which restores the interface to be similar to the version on Big Sur, except it still has Tab Groups and the interface changes color depending on the website. This option can be turned off. They also brought back the refresh button as well. Thank God! Good change!

Folks talked a lot here about Apple making some of the changes into new options. It's a little uncharacteristic of them, but I'm liking it.
It's the best way. Now everyone can have it the way they want.
The interface taking the color of the page works in either option.
