If you upgrade your Mac to the newly released OS 10.11 then you might encounter some problems knitting files to PDF via LaTeX. (If you are interested in the details for why this happens see: here).
Maybe the easiest solution to explain is just to re-download and install MacTeX.
Please post any post-Mac Upgrade problems you might have to this thread.
