This is a different thing, but I've just been faced today with the  
problem reported earlier on 20 May ([XeTeX] Font sizes in footnotes,  
and dashes), and which apparently is still there:

Attempting to use \fontspec or \newfontinstance with the Apple  
Symbols font, I'm getting:

> ! Font \zf at fonttwo=Apple Symbols/I at 10.0pt not loadable: ATSUI  
> font not found

> {\fontname \...

whereas I wasn't requesting Apple Symbols in italic or bold shape at  
all. It seems \fontspec and \newfontinstance supppose any font to  
have bold, italic and bold italic versions, and that XeTeX doesn't  
fail gracefully to load them.

Thus it seems I'm stuck for now with using:

     \DeclareFontFamily{U}{applsym}{}
     \DeclareFontShape{U}{applsym}{m}{n}{<-> "Apple\space Symbols"}{}
     \DeclareTextFontCommand{\applesymbol}
       {\normalfont\fontencoding{U}\fontfamily{applsym}\selectfont}

instead of:

     \newfontinstance{\applesymbol}{Apple Symbols}

No need to hurry to fix this in any case: I was just doing a quick  
test this morning, as a small break from a very boring job I'm  
otherwise doing (in Pages); I won't be using XeTeX again for one to  
three weeks.
