Until we can properly fix QPalette and QMacStyle,
we should disable dark appearance in Qt applications.
Disable by setting NSApp.appearance to Aqua, unless
dark mode support has been requested via Info.plist
or environment variable.
Read the NSRequiresAquaSystemAppearance Info.plist
key, don’t set NSApp.appearance if its value is false.
Also check the QT_MAC_REQUIRES_AQUA_SYSTEM_APPEARANCE
environment variable and apply similar logic. You then
enable dark mode support by setting:
QT_MAC_REQUIRES_AQUA_SYSTEM_APPEARANCE=0
which is slightly awkward, but matches Info.plist
behavior.
