How to install macOS Monterey public beta

If you’re interested in installing and trying out macOS Monterey public beta, you now have the opportunity to do so as it became available to download for any Mac user.

Beta system software is typically less stable and more prone to bugs and incompatibilities, so installing the macOS Monterey public beta should be reserved for more advanced users, preferably on secondary Macs. Nonetheless, installing and running MacOS 12 public beta is pretty easy, so if you’re up for testing out the upcoming system software version, read on as this tutorial will walk through the process of getting it setup on a compatible Mac.

When installation has completed, macOS Monterey will boot up on the Mac.

How do install future macOS Monterey beta updates?

Once you’re running macOS Monterey public beta, it is important to regularly install beta updates when they become available. Installing the beta updates is done just the same as any other system software update, by going to  Apple menu > System Preferences > Software Update.

When the beta period ends, you will be able to update directly from the macOS Monterey public beta to the final version. That is expected to happen sometime in the fall.

What if I encounter bugs with macOS Monterey beta?

You almost certainly will encounter something that is a bug or not working as expected, that is par for the course with beta system software. The best thing to do with bugs found is to report them to Apple by using the built in “Feedback Assistant” app that gets installed onto the Mac running the Monterey beta. You will find Feedback Assistant in the Dock and the Applications folder.

If you are experiencing bugs with a third party app, contacting the developer of that app directly is typically how you report those bugs. Note that many developers are actively working on bug fixes for macOS Monterey.

MacOS Monterey is too buggy, how do I downgrade and revert back to Big Sur?

If you made a Time Machine backup prior to installation (as you should have!) you can easily downgrade from macOS Monterey by booting up from Time Machine, erasing the hard drive, and restoring from the Time Machine backup. We will cover the full downgrade process is another article for those who are curious.

If you’re interested in running macOS Monterey beta, you might also be curious about installing and running iOS 15 public beta and iPadOS 15 public beta on an iPhone or iPad as well, so check that out too.
