Download & Install MacOS Sierra Public Beta Right Now
MacOS Sierra Public Beta is now available to download and install for any Mac user interested in testing the upcoming operating system. Remember that beta system software is less stable and notoriously buggy, so this experience is recommended for more advanced users or those with a secondary computer they don’t mind running beta system software on.
This guide will walk through how to enroll in the macOS Sierra public beta program, as well as how to download and install macOS Sierra 10.12 public beta onto a Mac.
Be sure the Mac is compatible with MacOS Sierra, and that you make a fresh backup with Time Machine before beginning.
How to Download & Install MacOS Sierra Public Beta
- Back up the Mac with Time Machine before anything else, do not skip making a backup or you may lose your stuff and ability to downgrade
- Visit the official Apple Beta Program page for Mac OS Sierra here and log in to your Apple ID
- Scroll down to the “Install MacOS Sierra Public Beta” section and click on the blue “Redeem Code” button to launch the Mac App Store
- The code should automatically redeem and MacOS Sierra Public Beta installer should start downloading
You can check the progress of the download in the Purchases tab of the App Store:
Once macOS Sierra has downloaded, the installer will launch itself. If you want to create a bootable USB installer for macOS Sierra beta, quit the installer and do that first, otherwise you would have to re-download it again.
The safest way to test out beta system software on a single machine is to install macOS Sierra public on a separate partition on a Mac and dual boot, thus preserving the primary operating system. It is not recommended to update an existing Mac OS X release to a beta version, as it will be less stable than expected. Another option would be to install the public beta onto a secondary Mac. Regardless, always back up a Mac first, skipping a backup made lead to data loss or worse.
If you don’t care about making a boot installer or partitioning the drive first, you can go ahead and run the installer to install or update to macOS Sierra public beta.
Once MacOS Sierra 10.12 has been installed, the Mac will automatically reboot and the computer will be running Mac OS X 10.12 public beta. Future public beta builds will come through the App Store “Updates” tab as usual.
If you’re interested in beta software, you may also want to download and install iOS 10 public beta on iPhone or iPad too.
