Howdy,

If the person is using pstricks a lot they should be typesetting the file using latex->dvips->ps2pdf unless they are also including pdf, png and/or jpeg images in their document. The easiest way to tell TeXShop to use that method of typesetting is to put the line

% !TEX TS-program = latex

at the top of the file.

Using the auto-pst-pdf package is more than simply loading the package. It provides wrappers (environments or commands) to be put around all pstricks/psfrag/etc. graphics and compiles them separately and finally adds the results into the document. As I stated above, there is no need to use it unless the person is also including pdf, png and/or jpeg images in the document.

If the file is being typeset within TeXShop the -shell-escape is the default so there is no need to add it. Not only that but using the latex->dvips->ps2pdf methos of typesetting, if possible even negates the necessity of having it.

Good Luck,
