Upgrading to macOS Big Sur can be an exciting experience, but it can also come with its own set of issues. One common problem that users have reported is the 'macOS Big Sur update not found' error when trying to install or update Homebrew on their Mac. If you're experiencing this issue after upgrading from Mojave to Big Sur, don't worry - we're here to help you troubleshoot and fix it.

Check Your Command Line Tools

The first step in troubleshooting the 'macOS Big Sur update not found' error is to ensure that your command line tools are installed correctly. To do this, open your Terminal app and run the following command: `xcode-select -install`. This will install the necessary command line tools for Homebrew to function properly.

Verify Your Homebrew Installation

After installing the command line tools, try running the `brew list` command again to see if you're still getting the 'macOS Big Sur update not found' error. If you are, it's possible that there's an issue with your Homebrew installation. Try reinstalling Homebrew by running the following command: `ruby -e '$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)'`.

Check Your OS Version

Another potential cause of the 'macOS Big Sur update not found' error is that your OS version may be outdated or incompatible with Homebrew. To check your OS version, run the following command: `sw_vers`. This will display your current OS version and build number.

Enroll in the Apple Developer Program
