Have you considered using TeXShop as a PS previewer: when TeXShop is 
asked to open a PS file, it launches ps2pdf (GhostScript's distiller 
script) in the background and displays the resulting PDF file; 
alternatively it can also be set to use pstopdf (Panther's distiller 
binary, invoked by Preview as well).

There may be situations when Panther's distiller is more appropriate 
than GhostScript's distiller, for example when processing a PS document 
containing Mac OS fonts (I'm not sure this is deterministic and 
reproducible, but I've met this problem once). I also met the case 
when, wanting to include an EPS picture inside a XeLaTeX document by 
converting it to PDF first, I got bad results when the conversion had 
been performed by GhostScript and good results when it had been 
performed by Preview.

There may also be situations when a PDF file cannot be displayed 
properly by Preview but is displayed properly by Adobe Reader. I've met 
this situation, for example, when viewing one of the versions of the 
European Constitution Treaty available from the EC site: this version 
had been prepared with MS Word + Neevia Document Converter, and was 
displayed correctly by Adobe Reader but as a succession of empty boxes 
and random  characters by Preview.

Thus in any case you may use TeXShop (or the scripts 
/usr/local/bin/ps2pdf and /usr/bin/pstopdf) as a distiller and Adobe 
Reader as a previewer.
