I doubt it works on MaxOSX. You're not separating the two
commands, so "print", "-D" and $PWD are treated as arguments to
"builtin cd".

cd() {
  builtin cd "$@" &&
    print -rD $PWD
}

"&&" as you probably want to print the current directory only if
cd succeeds.

You need -r, as you don't want \x sequences to be expanded.

If you want to print the directory regardless of whether cd
succeeds, you should at least make sure you return cd's exit
status:

cd() {
  local ret
  builtin cd "$@"
  ret=$?
  print -rD $PWD
  return $ret
}
