Apple has been encouraging developers to use Cocoa instead of Carbon for several years now. I'm not privy to their reasons for this change, but it is probably more marketing than technical, though it may be partially technical as well. This change will probably affect the way we render on the Mac. I haven't fully wrapped my head around all this Cocoa stuff yet (Eric Wing has a much better grasp on this) but once the windows are set up, OSG proper should Just Work (TM). I tested compiling OSG for 64-bit using the x86_64 build architecture and, as expected, the libraries built fine except for osgViewer. I'm hoping that we can create a drop-in viewer using Cocoa instead of the current Carbon-based viewer but I just don't know. I'm still too new at OSX programming stuff to really give a good answer. Perhaps other Mac developers can chime in here.
