Update MacOs to Sonoma - Cannot Run Git: xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

The error you're seeing typically occurs after a macOS update when the Command Line Tools for Xcode are either missing or outdated. Here's how you can resolve it:

Solution: Reinstall Command Line Tools

Open Terminal: You can do this by searching for "Terminal" in Spotlight (press Cmd + Space and type "Terminal").
Install Command Line Tools: Run the following command to reinstall the Command Line Tools:
```
xcode-select --install
```
- This command will prompt you to install the necessary tools. Follow the on-screen instructions.
Check the Installation: After the installation completes, verify it by running:
```
xcode-select -p
```
- This should return a valid path like /Library/Developer/CommandLineTools.
Test Git: Try running a Git command, such as git --version, to confirm that Git is working correctly.

If the above steps don't resolve the issue, you may need to accept the Xcode license:

sudo xcodebuild -license

After accepting the license, test Git again. This should resolve the problem.

If sudo xcodebuild -license gives error

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

It seems that the system is recognizing the Command Line Tools but expects a full Xcode installation to proceed with the xcodebuild -license command. Here's how you can handle this:

Option 1: Install Xcode

Install Xcode from the App Store:
- Open the App Store and search for Xcode. Download and install it.
Set the Active Developer Directory to Xcode:
- After installing Xcode, you might need to set the active developer directory to Xcode:
```
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
```
Accept the License:
- Run the license command again:
```
sudo xcodebuild -license
```

Option 2: Reinstall Command Line Tools (If you don't want full Xcode)

If you prefer not to install the full Xcode, try the following:

Reset Command Line Tools Path:
- Run the following command to reset the path:
```
sudo xcode-select --reset
```
Reinstall Command Line Tools:
- Reinstall the Command Line Tools:
```
xcode-select --install
```
Test Git:
- Try running git --version again to see if the issue is resolved.

These steps should fix the problem by either ensuring that Xcode is fully installed or by correctly setting up the Command Line Tools.

NOTE: If xcode-select --install gives message xcode-select: note: install requested for command line developer tools

The message xcode-select: note: install requested for command line developer tools indicates that the system has acknowledged your request to install the Command Line Tools. Here’s what typically happens next:

Installation Prompt:
- After running xcode-select --install, a pop-up window should appear prompting you to install the Command Line Tools.
- If the pop-up appears, follow the on-screen instructions to complete the installation.
If the Pop-up Doesn't Appear:
- Sometimes the installation pop-up may not show immediately. If this happens, you can try the following:
  - Manually Trigger the Installation:
    - Open the Terminal and run this command:
```
softwareupdate --list
```
    - If there are updates available, including Command Line Tools, it will list them. Then, you can install them using:
```
softwareupdate --install --all
```
Verify the Installation:
- Once the installation is complete, verify it by running:
```
xcode-select -p
```
- The output should be /Library/Developer/CommandLineTools if the Command Line Tools are installed correctly.
Test Git:
- Run git --version to check if Git is working now.

If everything works, your Git should be functioning again. If you still encounter issues, restarting your Mac can sometimes help complete the installation process.
