Texmaker and TeXstudio ⇒ PDFLaTeX isn't compiling

[Buchstabenalphabet]

After having set up my Computer (OS X, 10.9.4), the command "PDLaTeX" in Texmaker is not working anymore. I don't get an error message, but the document is not compiled. (the Bericht.pdf is not overwritten/ renewed).

I have tried to use latex, DVI->PS, PS ->PDF instead.
The latex command is working, but when I use DVI->PS, I get the following error:

could not start the command : "/usr/texbin/dvips" -o "Bericht".ps "Bericht".dvi

I have the same problem, when I use texstudio instead. When I use Tools -> Commands -> PDFLaTeX, I get the following error:

Command txs:///pdflatex not defined

Could anyone tell me, what the problem might me or how to solve it? I have installed the same MikTEX distribution that I had before.

MiKTeX is not running on OS X. Install MacTeX 2014. Btw. if you are German, perhaps join our partner site TeXwelt.de which provides support in German. We share the same server.

Thank you very much for your help! The problem was indeed a wrong installation... It is perfectly working now.
