Would I have to add the path in the preamble then?

Ah, I guess that could be exactly what I would have to enter in the  
Mac-terminal. As far as I know this is what the terminal is for: to  
enter linux-commands. I entered the line without installing anything  
and the terminal prompted me to enter my pw.

So I think I now also know, what running a texhash is. Thank you!
