The next version of MacOS is official.

While at WWDC 2017, Apple announced and previewed MacOS High Sierra, a major update to the MacOS Sierra operating system that released last year for Macs. It includes many behind-the-scene upgrades that will make your Mac seem more powerful, more secure, and faster. For instance, it will allow for VR and AR content. Browse Pocket-lint's roundup for more changes included in High Sierra.

But you don't have to wait until 25 September to try all these new features. Apple just opened the High Sierra public beta program, marking yet another time the company has allowed anyone to download and run a major pre-release version of its desktop OS before a formal release. It also just opened the iOS 11 public beta program for iPhone and iPad users. You can read all about that from here.

If you want to get MacOS High Sierra up and running on your Mac now, Pocket-lint has detailed everything you need to know below.

  5. On the Enroll Your Devices website, you’ll see instructions to back up your computer using Time Machine.
  6. You’ll also see a section called “Install the MacOS High Sierra public beta". Here, you’ll find a redemption code. Click the Redeem Code button.

  8. Enter your Apple ID password to download the installer.
  9. You'll also get an email inviting you to download the MacOS High Sierra beta.

Before you get excited about High Sierra, see if your Mac is compatible:

The High Sierra public beta is not the final, stable version intended for all consumers. The final version will release this autumn. As for the public beta version, it might include several bugs that have yet to be discovered or fixed. You should therefore only download and install the beta on a machine that's not your primary computer. And always back up your data and files first (see Apple's support page).

The OS X and iOS public betas come with a Feedback Assistant app, which can be opened from the second page of the Home screen on your iOS device or from the Dock on your Mac. You can learn more about the app here. The app is also available from the Help menu of any app.

Starting 25 September, the finished version of MacOS High Sierra will roll out to Mac users via an over-the-air update. When High Sierra goes live, you can get it by clicking the Apple logo in the top left corner of the screen and then selecting About This Mac > Software Update.

Apple also has a guide and instructions on how to get both betas.
