I would suspect that they have to deal with the very issue you're dealing with. One of the best TeX front-ends for the Mac is TeXShop and it's open-source, so you should be able to peruse its source.
All TeXShop or another front end will do is run a TeX process (e.g., pdftex, xetex) on your TeX source, then display the result in a PDFView. You'd have to look at the TeX source to see what it does: http://xetex.sourceforge.net is one example.
