After releasing Public Betas of iOS 15, iPadOS 15, tvOS 15 and watchOS 8 yesterday for public beta testers, macOS Monterey Public Beta is now available as well.
Here’s how to install macOS Monterey Public Beta, which Apple says should be done on a secondary machine, since it is early release software.
Step 1: Back up your Mac using Time Machine.
Step 2: Download the macOS Public Beta Access Utility (if you are a new user) installer.
Step 3: With your Mac enrolled, download macOS public beta. Go to System Preferences > Software Update. Then click ‘Upgrade Now’ as you’ll see macOS Public Beta available.
Step 4: Once macOS public beta is downloaded, follow the steps of the installer.
You’ll be able to get updates for public beta as notifications will be sent to alert you of new builds. Just install these updates via System Preferences.
