Dear all,

did anybody manage to build an app that takes advantage of the automatic dark mode \
support in recent Qt versions on macOS.

For pip PyQt 5.13.1 adding

	<key>NSRequiresAquaSystemAppearance</key>
	<string>false</string>

to the Info.plist worked for app.bundles build with either py2app or pyinstaller, but \
fails on using PyQt 5.13.2 and 5.14.0 running on macOS 10.15.2 with the system \
message

> It does not make sense to draw an image when [NSGraphicsContext currentContext] is \
> nil.  This is a programming error. Break on void \
> _NSWarnForDrawingImageWithNoCurrentContext(void) to debug.  This will be logged \
> only once.  This may break in the future.

What changed between 5.13.1 and 5.13.2/5.14.0?

Without the above Info.plist entry the PyQt dialogs are never rendered in Qt's dark \
theme. Is there any way to have the PyQt dialogs rendered with the default Qt dark \
theme for apps running under macOS dark mode?

Thanks for any hint,
Marko
