[OS X TeX] how include .eps in TeXShop using default

[Murray Eisenberg]

How in TeXShop (2.43) do I go about getting an included .eps or .pdf 
file in the pdf output when I typeset a LaTeX source file?

I have

   \usepackage[dvips]{graphics}

in the preamble. And for getting the graphics, I try to use:


\begin{center}
\scalebox{0.5}{\includegraphics{mygraph.eps}}
\end{center}

Then no graphics whatsoever appears in the pdf file obtained by 
typesetting in TeXShop.

If, instead, I create my graphic directly as a .pdf (by export from 
Mathematica) and then use correspondingly \includegraphics{mygraph.pdf}, 
then in the output from typesetting in TeXShop the graphic appears but 
grossly enlarged and overwriting text. (The bounding box information may 
have gotten lost.)

(Sorry for this seemingly naive question. I'm a recent convert to MacTeX 
from the Windows world, and this sort of thing was very easy to do with 
an obvious workflow .tex -> .dvi -> .ps -> .pdf there.)
