It's because when xdvipdfmx is trying to load an non-CID OpenType
font, CIDFont_cache_find() will first attempt to load such font as a
Type2 font, which will trigger such a OS X resource fork access,
previously we had sfnt_open to replace that for XETEX:

-#ifdef XETEX
- sfont = sfnt_open(font->ft_face, SFNT_TYPE_TTC | SFNT_TYPE_TRUETYPE);
-#else
fp = DPXFOPEN(font->ident, DPX_RES_TYPE_TTFONT);
if (!fp) {
fp = DPXFOPEN(font->ident, DPX_RES_TYPE_DFONT);
@@ -553,7 +550,6 @@ CIDFont_type2_dofont (CIDFont *font)
} else {
sfont = sfnt_open(fp);
}
-#endif

The backtrace is as follow:

r34758 should fix this.
