Attaching supplement essays...

<p>So I am not nearly done with my supplement essays, but I wanted to see how they would look to the admissions people, and was wondering if I should double space or not. Anyway, that is not my topic of concern. When I went to attach the essay, they said a lot of file types were allowed, including the one I use (.docx, I have a mac). I went to attach the essay, and it said it uploaded correctly, but when I went to view it, a blank white .pdf showed up, showing me nothing was there.</p>

<p>Is there any fix to this situation? Should I try saving it as a .doc or .pdf?</p>
