If you want to download MacOS Big Sur, follow these steps:
1. Back up your Mac, just to be safe. You don't want to risk losing everything when you upgrade.
2. Make sure that you are running OS X 10.9 or later, and have 4GB of memory available, and 35.5GB available storage.
3. On your Mac, go to apple.com/macos/big-sur. Or, go to System Preferences > Software Update, and find MacOS Big Sur. Either way, click Upgrade Now. The download will start immediately, but may take while -- for my MacBook Air, it estimated about an hour.
Once you download and install the update and restart your computer, you'll be running on MacOS Big Sur.
