wxPython package for OSX 10.11 / MacOS Sierra
It seems like package structure has been changed since OSX 10.11 El Capitan, and current downloadable wxPython package file is not compatible with this version of OS. So we need to repackage them manually. My repackaged pkg file for wxPython3.0-osx-cocoa-py2.7: Download All credits goes to The Useless DaviXX'Blog . Visit official web page for more information.
