Assuming you have TeXLive from either 2012 or 2013, everything needed is already installed and enabled unless you specifically disabled some of the fonts that come wih TeXLive. So, in the preamble of your .tex file you'll have one or more lines that load fonts. For example,

\usepackage{mathpazo} % load palatino clone with pazo math fonts
\usepackage[bb=boondox,scr=rsfso]{mathalfa} % replace its Blackboard bold and use rsfso for \mathscr.

Effectively, TeXShop defers to TeXLive for all TeX processing, and that uses the entire elaborate TeXLive "kpathsea" (Karl's path search, cut to 8 characters) library for finding files, but only in the texmf trees. It certainly doesn't search Downloads. You may use kpsewhich to find file locations. Eg, in a Terminal window, type

/usr/texbin/kpsewhich stix-mathbb.pfb

gives you its path.
