I ran the code in your email and it works error free.

	macOs 10.12.3
	python 3.5.2 and 3.6.0 with PyQt5 5.7 and 5.8.1

What versions are you using?

I put your code into file a.py and run it from the command line as:

	$ python3.6 a.py

Note: that this example bumps into macOS specific handling of menus.

The File>Exit menu is automatically moved to the Python menu as Quit with Cmd-Q as the short cut the icon does show up.

I have signed up as a developer and still cannot find it. I do not see the correlation between apple and this PyQt5 program though. I also do not see anywhere in the code that would mention needing this folder.
