Set fish shell as default in macOS

How to set fish shell as default shell in macOS.

1. Install fish with brew install fish
2. Test the installation by running fish
3. Add the path fish to /etc/shells. First, get the path with which fish. In my case the path is /opt/homebrew/bin/fish. You can append the path with the command sudo sh -c 'echo /opt/homebrew/bin/fish >> /etc/shells'
4. Set the shell with chsh -s /opt/homebrew/bin/fish
5. Log out of your current shell
