Apple has released the third public beta for macOS High Sierra 10.13.6. To install it, you need to enroll in Apple’s beta software program. Follow our guide to download and install the public beta on your MacBook, iMac, Mac Mini or Mac Pro.
A public beta is different from a developer version because it is considered stable enough to be available for a large audience. Anybody who wants to install a public beta build of macOS can easily sign up. Meanwhile, for developer releases, you need to be registered with Apple’s developer program to download and install the builds.
Even though public builds are generally more stable than developer versions, please be cautioned that it is still not final release quality software.
Download macOS High Sierra Public Beta 3
Apple has a beta software program, where users can register and enroll their devices to download and install macOS public test releases. Before we proceed, make sure to back up your Mac using Time Machine. You would need to use an external hard drive to use Time Machine. Connect it to your Mac, go to System Preferences > Time Machine to back up your computer. The first back up takes a long time, but it’s better to be safe than sorry!
- Register on Apple’s Public Beta Software Program website. You can use your existing Apple ID to login.
- Now it is time to enroll your Mac. This is done by download and installing the macOS Public Beta Access Utility from Apple. It is normally available to download from this page.
- Once you install the utility, your Mac will now be eligible to download and install macOS beta. The installer automatically opens up Mac App Store, so you can simply click on the Updates tab to download the latest macOS High Sierra release.
- Once you download the beta, the macOS installer (also accessible from Applications folder) will open to complete the rest of the update process.
If you want to do a clean install using the public release, you can create a bootable USB drive with the macOS build you downloaded from the Mac App Store. The flash drive can also be used to install the build on another computer, without enrolling it in the beta program.
When you install the public beta, you will notice that a Feedback app is also installed on your Mac. As you would be using test software, it is a good practice to share feedback on features and bugs.
How to leave macOS public beta program
If you want to stop using macOS test builds, here is what you should do:
- Open System Preferences and click on App Store.
- Next to the line that says that your computer is set to receive beta software updates, click on the Change button.
- Click on do not show beta software updates.
This will not revert your Mac to a non-beta release of macOS. However, when the next general release of macOS is available, your Mac will be updated to it. An alternative is to follow our guide on how to clean install macOS, but this only helps if you had backed up your data, as it will reset your Mac.
