This problem has confused me for a while.
I set the mainfont garamond in my tex file:
\setmainfont{Garamond}
And it runs perfectly in my Windows laptop.
However, I use it on my Mac and there is an error:
xdvipdfmx:fatal: Cannot proceed without the font:
/Library/Fonts/Microsoft/Garamond
I check /Library/Fonts/Microsoft/ folder and the Garamond is there. But the xelatex compiler just complains about the font.
I don't know how to fix it. Can anyone help me?
