macOS Sierra Broke My Git

One morning I was running git status. I got this ugly error message in my terminal:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

This is of course not very workable. I installed macOS Sierra last night. After reading some posts on disableing System Integrity Protection I found a StackOverflow issue on this subject. It didn’t need to disable any System Integrity Protection, just one simple command:

xcode-select --install

Git was working again. Unfortunatly Homebrew still had issues like

Error: /usr/local is not writable. You should change the ownership
and permissions of /usr/local back to your user account:
  sudo chown -R $(whoami) /usr/local

but just do what Homebrew says and you’re done!

Happy coding! – Found a mistake or a typo? Please submit a PR to my GitHub-repo.
