Add Git Branch Name to Terminal Prompt on Mac (Big Sur)

Open ~/.zprofile or ~/.zshrc in your favorite editor and add the following content to the bottom. ( if the file ~/.zprofile or ~/.zprofile does not already exist create it)

# Git branch in prompt.
function parse_git_branch() {
    git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}

COLOR_DEF=$'\e[0m'
COLOR_USR=$'\e[38;5;243m'
COLOR_DIR=$'\e[38;5;197m'
COLOR_GIT=$'\e[38;5;39m'
setopt PROMPT_SUBST
export PROMPT='${COLOR_USR}%n ${COLOR_DIR}%~ ${COLOR_GIT}$(parse_git_branch)${COLOR_DEF} $ '

then source ~/.zshrc or source ~/.zprofile to refresh changes

Differences between .zprofile and zshrc:

~/.zprofile is only sourced when zsh is run as login shell, e.g. when logging in on the console or via SSH.

It will not be sourced by zsh when opening a new terminal or starting a new zsh session from within a running session. Anything you need in all interactive sessions, should be set in ~/.zshrc. Anything you need in all zsh sessions, including scripts, should be set in ~/.zshenv.

I edited my /etc/zshrc file and quit the terminal and start it again. Worked as expected. Thanks.
