Always be careful when downloading beta software. It could potentially contain bugs. I recommend backing up important data first. Then follow these easy steps to install macOS 11 Big Sur:
- Make sure that your Macbook or iMac is enrolled in the “Apple Developer Programme.” Just use your Apple ID to register.
- Download the macOS Beta profile from the website https://betaprofiles.com/.
- Open the “System Preferences” app on your Mac and click on “Software Update”.
Congrats! You are now able to download Apple’s new version of MacOS.
