How to install the macOS Monterey public beta

Apple has released a beta version of macOS 12 Monterey so anyone who wants to can try the new operating system, before it launches this fall.

The macOS Monterey public beta is available to anyone with a compatible Mac and does not require a developer account. Here we explain the steps to install the beta.

Before downloading the update, it's worth noting that Apple does not recommend installing macOS Monterey Public Beta on your regular Mac, so if you have a secondary Mac, use it. This is beta software (not final) and often there are bugs and problems that can prevent the software from working properly or cause other problems, such as incompatibility with other software that you need on a daily basis.

There are also some major design changes in Safari that take some getting used to, so you may want to avoid being forced into the beta until you're sure it suits you.

Compatibility with MacOS Monterey

macOS Monterey is compatible with many of the Macs that were capable of running macOS Big Sur, but removes support for some older 2013 and 2014 MacBook Air and iMac models. The following Macs can run the software.

  • iMac - Late 2015 and later
  • iMac Pro - 2017 and later
  • MacBook Air - Early 2015 and later
  • MacBook Pro - Early 2015 and later
  • Mac Pro - Late 2013 and later
  • Mac mini - Late 2014 and later
  • MacBook - Early 2016 and later

Back up with Time Machine

Before upgrading to Monterey beta, be sure to back up using Apple's Time Machine backup feature to an external drive.

If you want to go back to your old settings after trying macOS Monterey or if you encounter an error and need to roll back, you will need to reinstall macOS Big Sur (or your previous operating system) and a backup can be useful to undo that.

Sign up for the beta software program

MacOS Big Sur installation requires registering your Mac with Apple's free beta software program. Follow these steps to do it.

  1. Visit the Apple Beta Software Program website with a browser on your Mac.
  2. Click on the blue button  to register  or, if you are already registered, click on login.

  4. You agree to the terms and conditions of the Apple Beta Software Program.
