title: xelatex not finding font on Mac
body: <p>I'm trying to use the polyglossia package along with xelatex to compile some Arabic text. It seems that xelatex is not recognizing the fonts that I have installed.</p>
  
  <pre><code>\documentclass{article}
  
  \usepackage{geometry}
  \geometry{letterpaper}
  \usepackage{setspace}
  
  \usepackage{fontspec}
  \usepackage{polyglossia}
  \setmainlanguage{english}
  \setotherlanguage{arabic}
  \newfontfamily\arabicfont[Script = Arabic]{Scheherazade} 
  
  \begin{document}
  
  \begin{Arabic}
  
  انطلقت الثورة الليبية منذ أكثر من سنة متوازية مع ثورات الربيع العربي الأخرى التي 
  
  \end{Arabic}
  \end{document}
  </code></pre>
  
  <p>When I try to compile this using xelatex, I get the following error:  </p>

  <p>I'm on a Mac and I've tried to search for answers to this. I've made sure that the Scheherazade font is installed on my computer (it appears in FontBook). I've tried doing</p>
  
  <pre><code>\newfontfamily\arabicfont[Script = Arabic]{Scheherazade-R.ttf} 
  </code></pre>
  
  <p>as well to no avail. Any suggestions? It seems like it's not recognizing the font even though it's installed on my system.</p>
