Apple - For iTerm2, how do I make the working directory appear in the window title?

With the \033]0;TEXT\007 escape sequence.

Example of use in Bash: echo -ne "\033]0;$PWD\007"

Which you could add to your $PROMPT_COMMAND if you use Bash, or otherwise attach to you PS1 so it gets re-evaluated often.

Example: export PROMPT_COMMAND='echo -ne "\033]0;$PWD\007"'

If you're using zsh (which is the default in macOS 10.15), put this in your ~/.zshrc instead:

if [ $ITERM_SESSION_ID ]; then
precmd() {
  echo -ne "\033]0;${PWD##*/}\007"
}
fi

You can also spell \033 as \e and \007 as \a.

I like this answer from this gist to add it to the tab title

# put this in your .bash_profile
if [ $ITERM_SESSION_ID ]; then
  export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
fi
