[OS X Emacs] aquamacs texlive update

[Inge Koch]

Hello together!

I am new to emacs and use it to write in latex. I have install texlive 2012 on my System, but aquamacs always use texlive 2008. In the system requirements on my mac I have choosen texlive 2012. How can I get this? How can I get aquamacs to work with texlive2012? 
My english is not the best, but I hope you can understand my problem.
Thanks in advance
Inge
