wx.EVT_KILL_FOCUS is not fired on OSX, so we have to use a different event to save. I thought EVT_STC_CHANGE of wx.stc would be a good choice. See http://www.yellowbrain.com/stc/events.html#EVT_STC_CHANGE Altered gcodeTextArea slightly to use the new gcodeTextArea on OSX as well.
Cura
If you are reading this, then you are looking at the development version of Cura. If you just want to use Cura look at the following location: https://github.com/daid/Cura/wiki
Development
Cura is developed in Python. Getting Cura up and running for development is not very difficult. If you copy the python and pypy from a release into your Cura development checkout then you can use Cura right away, just like you would with a release. For development with git, check the help on github. Pull requests is the fastest way to get changes into Cura.
Packaging
Cura development comes with a script "package.sh", this script has been designed to run under unix like OSes (Linux, MacOS). Running it from sygwin is not a priority. The "package.sh" script generates a final release package. You should not need it during development, unless you are changing the release process. If you want to distribute your own version of Cura, then the package.sh script will allow you to do that.
