[OS X TeX] [MacTeX 2015] Cannot open Ghostscript for piped input

[Ettore Aldrovandi]

It’s possible that user 504 is you or some alternative version of yourself in previous installation. 504 is a uid; yours can be found by running the command ‘id’ in the terminal.

Another strange thing is the presence of a directory git under /usr/local?

I guess there is an error in the installation script (I mean it asks for admin privileges) or it's parallels fault (cause there are some files inside this folder, too).
