mediawiki at mac. Problem with formulas.

Hello, I try to install mediawiki at the Mac OS server, and it fails.
First I tried with the texvc. It seems to have the irrecoverable bug: there is no way to indicate the correct path /usr/texbin/latex in the LocalSetting.php profile, and the texvc always looks to ~/Sites/usr/texbin/latex instead; but the lates does not work being copied of moved to such a directory.
Now I try with MathJax. I should appreciate the advices. From my side I plan either describe, how does it work or in which a way it fails.
