Building with Qt4 and Python 2.7
FreeCAD has transitioned from Qt 4 to Qt 5 as well as homebrew. Qt 4 is no longer available as an option for new build on macOS following Qt 5 transition. Python 2.7 has been deprecated within homebrew and upcoming macOS and we do not support it anymore for macOS build either.
