I'm trying to get AUCTeX up and running in macOS and linux and have followed the steps here.
(The site has a separate guide for GNU/Linux.) My problem remains invariant between OSes, so I'm asking for help.
In each instance, loading a .tex file, I note that Emacs shows my mode as
LaTeX/PS -- should this not say AUCTeX?
In any case,
C-c C-c brings up
Command (default latexmk), and another
C-c C-c is undefined.
Any suggestions where something might be amiss?
