True enough:

============================================================
sudo find / -name 'texmf.cnf'
==>
/Installeurs/XeTeX/xetex-0.9999.3/source/texk/kpathsea/texmf.cnf
/Installeurs/XeTeX/xetex-0.9999.3/source/texk/web2c/etexdir/etrip/texmf.cnf
/Users/boitet/Library/texmf/tex/latex/pgf_2.10.tds/doc/generic/pgf/text-en/texmf.cnf
/usr/local/texlive/2011/texmf/web2c/texmf.cnf
/usr/local/texlive/2011/texmf-dist/doc/generic/pgf/text-en/texmf.cnf
/usr/local/texlive/2011/texmf-dist/doc/latex/pgfplots/texmf.cnf
/usr/local/texlive/2011/texmf.cnf
/usr/local/texlive/2015/texmf-dist/web2c/texmf.cnf
/usr/local/texlive/2015/texmf.cnf
/usr/local/texlive/2016/texmf-dist/web2c/texmf.cnf
/usr/local/texlive/2016/texmf.cnf
/usr/local/texlive/2016basic/texmf-dist/web2c/texmf.cnf
/usr/local/texlive/2016basic/texmf.cnf
============================================================
But, then, how comes this file (texmf.cnf) is not found when I run TeXShop in 
mode XeTeX or XeLaTeX?

The other question is why I seem not to be able to install the latest version 
of XeTeX "on top" of what exists.
Perhaps it is, actually, but why does it report looking for files in /opt/local 
when they have been installed in /usr/local ?

==> Il will try to solve this simply, hoping the latest version of xetex is 
contained in the latest version of MacTeX, which seems natural.


I just added to my profile:
setenv PATH "$PATH":"/usr/local/texlive/2016"

If I understand well, it should solve the problem... but it does not at the 
moment. 

I'll update my system and restart tomorrow, perhaps that will help.

Question: is there is somewhere a PATH variable specific to TeX (some PATH_TEX 
or TEX_PATH)?

I did not find a place in TeXShop where I could specify which instance of 
TeXlive it should use.
Perhaps it is still using texlive/2011 or texlive/2015?
Tomorrow (too late now), I'll remove the older versions of TeXlive and the 
separate folder used to try to install semtex 0.99993 separately.

 
Best,
