Note that Org does not officially support Aquamacs. For now, I fixed
this particular issue because it also affects Emacs 25. However, this
part of Org is currently a subject of change. Feel free to join the
discussion at https://list.orgmode.org/87ee7yaksm.fsf@localhost/ to make
your voice (as Aquamacs user) heard.

Best,
