[Pythonmac-SIG] PyObjC - Apple sample code

Tue May 2 07:47:42 EDT 2017

I reinstalled python 2.7.13 from a fresh downloaded .pkg, and used pip to reinstall PyObjC, but I still get the same errors.
Do the Quartz example scripts work on python 3 ?

If you're building stuff for distribution to non-technical folks, build it with your own version of python (3) and ship it with py2app, not by copying scripts around.
