Ready to test out the new changes and features including a big UI refresh in macOS Big Sur? Follow along for how to install the macOS Big Sur beta on your Mac.

Apple unveiled the next major version of its Mac software, macOS Big Sur at WWDC20 as well as making its developer beta available. It comes with a big visual overhaul inspired by iOS, has a new Control Center, lots of Safari improvements, as well as modern widgets and notifications.

Keep in mind it’s generally a bad idea to run a developer beta on your primary Mac since there are performance issues and other bugs to be worked out.

Below we’ll look at how to install the free public beta (coming soon) as well as the developer beta (already available). Even though the iOS 14 public beta has been released, it’s not quite available for macOS Big Sur, but these are the steps when it does…

Mac: How to install the macOS Big Sur developer beta

  2. On your Mac, head to Apple’s Developer website
  3. Sign in if you’re not already by clicking Account (top right corner)

  10. The Software Update section of System Preferences should pop up
  11. The macOS Big Sur update should be available, click Upgrade Now

Note: Even though Apple is using macOS 11 as the marketing name, the first Big Sur beta is labeled as macOS 10.16.

Here’s how the process looks:

Now click “Allow” and open the beta.dmg and then the .pkg file.

Now follow the prompts to download macOS Big Sur on your Mac.

The macOS Big Sur beta is almost 10GB in size so it may take a while to download. When that’s done, you’ll see a dialog box to complete the installation.

While your mileage may vary, some have experienced a rebooting issue when installing Big Sur.
