Comment:

 Hah!  I found a reference in QApplication::macEventFilter, though not used
 in QGIS, that Mac events are handled differently in Qt Cocoa:

 > Cocoa uses a different event system which means this function is NOT
 CALLED when building Qt against Cocoa. If you want similar functionality
 subclass NSApplication and reimplement the sendEvent: message to handle
 all the NSEvents. You also will need to to instantiate your custom
 NSApplication before creating a QApplication. See Apple's NSApplication
 Reference for more information.

 So, the openDocumentsAEHandler() setup in main.cpp may not be called using
 Qt Cocoa.  This is way beyond me to try to fix.
