After upgrading just now my TexLive with TexUtility, I got an incompatibility with french in babel
Here is my MWE
\documentclass[11pt,a4paper,oneside]{amsart}
\usepackage[frenchb]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\begin{document}
c'est du français
\end{document}
It seems the problem comes from the installation of the e-french package instead of the frenchle one, but I do not know how to stop TexUtility doing its stuff. The only quick solution I found was to reinstall the MacTex 2015 installation and not upgrading it after. Any idea how to do better ?
