[PyQt] Working example of QMenuBar on OSX? Examples don't work

Ah. How are you running this program? e.g. from a command line, python
myscript.py , or how?
What you describe sounds like a problem with an app after it was bundled
by PyInstaller. Owing to the lack of some magical incantation in the app's
info.plist, the app's menus would not appear when it was launched, but if
it was hidden (or if another app was made active), when it came again to
the front, its menus did appear.
That has been fixed for PyInstaller with the latest (3.2) version. Anyway,
the code I showed you should work.
