I have found workarounds or solutions for all my problems so far, except for one: the headings are not in bold (as they used to in OSX 10.5).
Here is my code:
Code: Select all
\date{}
\usepackage{sectsty}
\usepackage{blindtext}
\usepackage{lettrine}
% Headings setup (sectsty)
\allsectionsfont{\sffamily}
\@ifundefined{XeTeXversion}{}{%
\usepackage{fontspec}%
\defaultfontfeatures{Scale=MatchLowercase,Mapping=tex-text}
\setromanfont{Minion Pro}%
\setromanfont[Ligatures={Common}, Numbers={OldStyle}]{Minion Pro}
\setsansfont{Gill Sans Std}%
\setmonofont{Courier New}%
}%
\usepackage{xunicode}
\usepackage{xltxtra}
