title: Python on OSX 10.11: Installation failed - no software found to install
body: <p>Starting a Python course via Udemy. Trying to install Python 3.2.3 (used in course) 64-bit on OSX 10.11.1, but running the dmg produces a msg saying the installation failed as it could not find the software to install. What goes wrong? Have installed python previously (other versions and on earlier OSX-version), and have never encountered this problem. Any suggestions re how to get around this?</p>
