Howdy,

I believe (I assume someone will tell me if I'm wrong --- certainly happened before) that:
if you call by the system font name (as given by Font Book) xe(la)tex looks in the standard font locations used by OS X (e.g., ~/Library/Fonts); if you call by the font file name xe(la)tex looks for the opentype (.otf) font within the fonts distributed with the TeX distribution. So when you used the otf file name with the old file name it looked in the TeX distribution and not ~/Library/Fonts where you have the font file; when you used the system font name the file in ~/Library/Fonts was found but that is not the updated version. Clear as mud?

Good Luck,
