Apple today seeded a new public beta of the macOS 12 Monterey beta to public beta testers, allowing non-developers to test the new macOS Monterey software ahead of its public release. The fourth beta comes two weeks after Apple released the third macOS Monterey public beta.


Public beta testers can download the macOS 12 Monterey update from the Software Update section of the System Preferences app after installing the proper profile from Apple's beta software website.

macOS Monterey introduces quite a few major updates for the macOS operating system. Universal Control, for example, lets a single mouse, trackpad, and keyboard be used across multiple Mac or iPad devices, and it's now possible to AirPlay directly to a Mac from an iPhone, iPad, or even another Mac.

Safari has an updated tab bar and support for Tab Groups to keep tons of tabs organized, and FaceTime now features support for spatial audio, Portrait Mode (M1 Macs only) and Voice Isolation for cutting out background noise. A SharePlay FaceTime feature lets Apple TV users watch TV, listen to music, and share their screens with one another.

Shared With You, another new 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 the Shortcuts app is now available on the Mac.

A dedicated Focus mode helps people stay on task by cutting out background distractions based on what's going on, and there's an updated Maps app with a whole slew of new features. With Live Text, Macs can now detect text in photos or provide details on animals, art, landmarks, plants, and more in images. The new beta adds Live Text support for Intel Macs.

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 complete overview available in our macOS Monterey roundup.

Yes since beta 4 Apple added Administrator authentication needed after download/preparation was completed before it installs. This is the dialog you see after the the system has been updated when you look at Software Update.

Add an other with a dead Outlook (FWIW I'm running the "New Outlook" version and up to date with the latest release)!! Luckily MAIL still runs so I'm OK for the short run. If it's OK for others, maybe it's a M1-related issue?

Yeah - it killed Outlook for me... any tips on getting it to work appreciated. If I reinstall from earlier Time Machine backup will I get the previous version of the beta?
You might to get on the latest Beta of Outlook and that one will work. Had the same issue but with the Aug 10 Update Outlook is working and no beachballs anymore. You can get it when you subscribe to the BETA channel.
Outlook Version that works is: 16.53 (21081001)
