I'm also on a Mac and it worked for me without any configuration.  You might need to check whether the TeX settings in your System Preferences are set correctly.  TeXLive installs a preference pane which sets the appropriate PATH variables via a GUI so you don't have to do any hacking on your .emacs file.  Also, you might want to look at using Aquamacs Emacs rather than the plain Emacs that ships with OSX because it comes pre-loaded with all the important customizations for LaTeXing.

Aloha Chao,

I have texlive 2010 installed on my Mac.  This path works for me:

**** Emacs set path to LaTeX binaries
#+begin_src emacs-lisp :tangle yes
   (setenv "PATH" (concat (getenv "PATH") ":/usr/texbin"))
   (setq exec-path (append exec-path '("/usr/texbin")))
#+end_src

HTH,
Tom

Dear all,

I'm trying to use org-mode under MAC, and when I export to html, some fragments of LaTeX needs to be converted. So I got the texlive installed and then put these lines into my .emacs:

8<------------------------>8

(defconst lch-mac-p (eq window-system 'mac) "Are we on Mac")
(if lch-mac-p
   (progn
     (setenv "PATH" (concat "/usr/local/texlive/2010/bin/universal-darwin:" (getenv "PATH")))
     (setq exec-path (append exec-path '("/usr/local/bin" "/usr/local/texlive/2010/bin/universal-darwin:")))
     )
   )

8<------------------------->8

But seems not work, org still can't find where the LaTeX is. Could anyone give me a hint?

Thanks in advance ^.^

Chao
