Howdy, In case you don't already know, TeX Live 2016 has been frozen and work has begun on testing TeX Live 2017. See <http://tug.org/texlive/pretest.html> for more information. You may get one final update to TeX Live 2016 using TeX Live Utility if you haven't updated recently. Good Luck, Herb Schulz (herbs at wideopenwest dot com)
