How to Install the New MacOS Big Sur Beta Right Now

macOS 11 beta

The macOS 11 Big Sur public beta has finally dropped for real. Here’s how to download and install it.

macOS 11 Big Sur features

macOS is all about integration and fluidity between Apple devices. It’s getting many of the new upgrades that iOS 14 is, such as Widgets, Maps, Message features and the Notification Centre.

This is probably because macOS is being primed to accommodate Apple’s new Apple Silicon chipset, which support iOS and iPadOS apps natively once its rolled out.

The Menu Bar and Sound Controls have also been reworked so they’re easier to interact with. Some brand new Mac Catalyst apps are also available on macOS 11.

macOS 11 Big Sur public beta

The public beta was supposed to go live in July. Ah well, better late than never. Now that’s been released, this is how you can get it on your Mac.

Firstly, make sure you back up your Mac first! If you’re not sure how to, Apple has explainers here.

Now you’re ready to head over to Apple’s public beta website. If you don’t already have an account — sign up!

Once you’re in, hit ‘enrol your devices’ and choose ‘macOS’. Scroll down and click on ‘Download the macOS Public Beta Access Utility’. Click ‘Allow’ to start the download.

In your downloads folder double click the macOSDeveloperBetaAccessUtility.dmg. This will open a new folder. Double click the pkg file inside it. Follow all of the prompts.

A software update folder should automatically launch. If it doesn’t go to Preferences > Software Update. At the top it should show the Big Sur public beta. Hit the ‘upgrade’ button. The beta should start installing. It’s a 9.5GB file so have some patience.

Next you’ll start the installation process. Hit ‘Continue’  and agree to the licensing agreement. Hit ‘Install’ and connected to a power source if you need to. Follow the prompts and installation will begin. Follow the prompts and installation will begin. The system will restart once its done. It’ll take a little while to finish the install so don’t stress about this.

From there it’s exactly the same process as the public beta.

In your downloads folder double click the macOSDeveloperBetaAccessUtility.dmg. This will open a new folder. Double click the pkg file inside it. Follow all of the prompts.

A software update folder should automatically launch. If it doesn’t go to Preferences > Software Update. At the top it should show the Big Sur public beta. Hit the ‘upgrade’ button. The beta should start installing. It’s a 9.5GB file so have some patience.
