Most of my files use the LaTeX rendering system to process my files. Some, especially those with customized fonts, use XeLaTeX. There are two ways to make Aquamacs process this file using the XeTeX engine. First, choose the menu options: command->TeXing Options->Use XeTeX engine.

Now you have a custom menu option under the Command menu that says XeTeX.
THIS WORKS ON AQUAMACS
In order to set this as the default on a specific file add the following local variables to your document. Add these at the end of the document, with the comment characters:
% Local Variables:
% mode: LaTeX
% TeX-command-default: "XeTeX"
% coding: utf-8
THIS WORKS ON EMACS
Close and reopen the document. Click ^C-^C <ret> and this will run XeTeX on your document.
