org-mac-iCal not working

Question

I am trying to setup org-mac-iCal See https://orgmode.org/worg/org-contrib/org-mac-iCal.html.

Nothing happens when Emacs loads. Even when I run the specific function org-mac-iCal, nothing happens still.

My configuration:

#+BEGIN_SRC emacs-lisp
(require 'org)
(require 'org-mac-iCal)
(add-to-list 'org-modules 'org-mac-iCal)
#+END_SRC

#+BEGIN_SRC emacs-lisp
(setq org-agenda-include-diary t)
#+END_SRC

#+BEGIN_SRC emacs-lisp
(setq org-agenda-custom-commands
      '(("I" "Import diary from iCal" agenda ""
         ((org-agenda-mode-hook
           (lambda ()
             (org-mac-iCal)))))))
#+END_SRC

The diary file remains empty. Incidentally, if the diary does not exist, this complains about that, but that's not really an issue.

My iCalendar has many calendars. They are all checked, per the documentation in the link above.

UPDATE: This package might be just too old?

Ok, it turns out that all one has to fix is the version that the org-mac-iCal expects (namely, just add your Mac version directly in this line: https://github.com/Fuco1/org-mode/blob/master/contrib/lisp/org-mac-iCal.el#L101).

The rest works beautifully. Be sure to read the docs: https://orgmode.org/worg/org-contrib/org-mac-iCal.html.
