OSX has its own unique ways to torture developers (and they keep
"improving" them :-)),
that's why it seems that Sage suffers from lack of testing on OSX...
Could you check if
sage: import dot2tex
works?
And one more sanity check:
sage: from sage.graphs.dot2tex_utils import have_dot2tex
sage: have_dot2tex()
Does this return True? (have_dot2tex() is some old function still used in
that code...)
With sagenb it's not working, and will not work; sagenb is
deprecated---switch to jupyter notebooks
(one advantage is that they can be used on SMC)
