The script oddly named "mptopdf" in TeXShop is from Nicola
Vitacolonna, and has been incorporated under this rather improper
name by Richard Koch in TeXShop >=2.28. You cand find it in /
Applications/TeXShop.app/contents/resources/mptopdfwrap, or in /Users/
The problems you report are probably from this script, not from the
original mptopdf. I suggest you report them to Nicola Vitacolonna (http://users.dimi.uniud.it/~nicola.vitacolonna/freesoftware.html
), and also to the "TeX on Mac OS X mailing list" (http://mactex-wiki.tug.org/wiki/index.php?title=TeX_on_Mac_OS_X_mailing_list
), to which Richard Koch participates (and Nicola Vitacolonna too, if
I remember well).
