Aha! Very clever -- I'm learning lots from you. Thanks for taking the time. 

It shows that same missing symbol, _NSPreferredScrollerStyleDidChangeNotification

Too bad that darned scroller needs to change style like that -- so much of qt5 would work otherwise on 10.6!

I wonder if I can get rid of that call somehow :>

Let me try some earlier 5.4 versions and see if this was a new addition ...
