Git is not working after macOS update ("xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools")

It looks like you're encountering an issue with Git after updating macOS. The error message you provided, "xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools)", suggests that there might be a problem with the Xcode Command Line Tools, which includes Git.

This error usually occurs when the Command Line Tools are missing or not properly configured after an operating system update. To resolve this issue, you can follow these steps:

    Install Xcode Command Line Tools: Open a terminal and run the following command to install the Command Line Tools:

    bash

xcode-select --install

This will prompt you to install the necessary tools. Follow the on-screen instructions to complete the installation.

Reset Xcode Command Line Tools: If the installation doesn't solve the problem, you can try resetting the Command Line Tools by running the following command:

bash

sudo xcode-select --reset

This command will reset the path to the Command Line Tools.

Reinstall Git: If the issue persists, you can try reinstalling Git:

bash

brew install git

If you don't have Homebrew installed, you can install it using the following command:

bash

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Once Homebrew is installed, you can proceed with installing Git.

Check PATH Configuration: Ensure that your PATH environment variable is correctly configured. The following line should be present in your shell profile configuration file (e.g., ~/.bash_profile, ~/.zshrc):

bash

    export PATH="/usr/local/bin:$PATH"

    This ensures that Git and other Homebrew-installed tools are accessible.

    Update macOS: If none of the above steps work, consider checking for any available macOS updates and installing them. Sometimes, system updates can also resolve compatibility issues.

    Contact Apple Support: If you're still facing issues after trying these steps, it might be a good idea to reach out to Apple Support or consult developer forums to get more specific assistance for your macOS version.

Remember to back up important data before making any major changes to your system. Additionally, always exercise caution when using sudo and executing commands with administrative privileges.
