      QMessageBox does not look like a native NSAlert dialog on Mac OS X.

      • QMessageBox displays close/minimise/zoom widgets in the title bar, but a modal dialog should not have these widgets (not even in a disabled state).
      • QMessageBox packs the window contents too tightly compared to the standard NSAlert layout convention.
      • QMessageBox makes the buttons too small compared to the standard NSAlert button widths.
      • QMessageBox does not display the application icon
      • and much more

      Comparison screenshots are attached.

      QMessageBox::information(nullptr, "Error", "This is the error message");

      vs

      QCocoaMessageBox::information(nullptr, "Error", "This is the error message");
