I just checked QWizard source file in Qt 5 and find the function 
responsible for get the default image, 
QWizardPrivate::findDefaultBackgroundPixmap(),
  is bracketed inside a #ifdef Q_WS_MAC macro.

Q_WS_MAC doesn't seem to be defined anywhere in Qt 5's header files.

What's more QPixmap::fromMacCGImageRef() used in 
findDefaultBackgroundPixmap() is no longer in Qt 5. Why?
