Unless I'm way off base here, you have to actually >select< the mac font in XeLaTeX, which it appears you have not done.

Most preambles that work with XeLaTeX have something along the lines of:
\setromanfont[Mapping=tex-text]{Zapfino}
\setsansfont[Scale=MatchLowercase,Mapping=tex-text]{Gill Sans}
\setmonofont[Scale=MatchLowercase]{Andale Mono}

There are about 45 different fonts on my relatively up-to-date computer with MS Office 2011 installed. Unfortunately, many of mine seem to be MS specific or CJK fonts, aside from the Apple fonts, which are relatively few and far between.
