The latest: Public Beta 9 now available

Apple released the latest version of its macOS Big Sur public beta on Wednesday, September 30. If you installed a previous beta version, you can get the update through Software Update, which is located in System Preferences. Otherwise, follow the instructions below.

Sign up for the program and install the macOS Big Sur Public Beta

Before you can install the new operating system, you must be enrolled in the Public Beta program. You can do this through Apple’s Public Beta program website. In the Get Started section of the website, click on the “enroll your Mac” link.

This should take you to the “Enroll you devices” webpage. Follow the instructions. In step 2, you will download the “macOS Public Beta Access Utility” which will enroll your Mac into the program. Then the utility will launch Software Update to download and install the Big Sur beta.

The installation takes a while. It can take about 40 minutes or longer, depending on your internet connection speed.

What is the macOS Big Sur Public Beta?

The current version of the Mac operating system is macOS 10.15 Catalina. The next version is macOS 11 Big Sur. Apple makes a public beta version of Big Sur available for people to try out, test against their favorite software, and report bugs to the company.

Since this is beta software, there’s a good chance it could cause problems on your Mac. You may encounter frequent freezes and crashes, or your apps may not work. Don’t count on it being stable enough to use all the time.
