Pass redirect=False to the App constructor.  You'll then see this 
because of your typo:

Traceback (most recent call last):
   File "/h/tmp/test/frame2.py", line 18, in <module>
     app = App(False)
   File "/projects/wx2.8/wxPython/wx/_core.py", line 7757, in __init__
     self._BootstrapApp()
   File "/projects/wx2.8/wxPython/wx/_core.py", line 7354, in _BootstrapApp
     return _core_.PyApp__BootstrapApp(*args, **kwargs)
   File "/h/tmp/test/frame2.py", line 10, in OnInit
     self.frame.SetBackGroundColour("light blue")
AttributeError: 'Frame' object has no attribute 'SetBackGroundColour'

But this is still true.  Top level windows on Mac can't have a bg color.
