In emacs -Q just need something to get the Alt key bound
e.g.
(setq mac-command-modifier 'alt)
The when you Type A-c you get ยข and you cannot bind it yourself.
On a mac I want the key by space to be Alt as that is what is printed on
my PC keyboard. I suspect this is true with PCs
The issue is that (require 'iso-transl) is called before the user can alter its behaviour and that iso-transl.el then binds to various A-c and other keys.
This makes it impossible to use Alt as a modifier key
load-history shows
(defun . iso-transl-define-keys)
(defun . iso-transl-set-language)
(provide . iso-transl))
(require . syntax)
In emacs 27 iso-transl was not called that early and only seem to be
called by describe-bindings and so could be overridden as shown in Aquamacs
Ideally iso-transl should only bind the A- keys if explicitly asked to
do so. At least the user shoulkd be able to configure the behaviour - as
exising emacs uses this wrong behaviour the default can be this setting
of A- keys but the user should be able to set something to stop this.
See
for other users finding this (and they are not Mac based)
