The problem with that thought is the lower level bits are very *nix but all the higher level bits like the GUI and other surrounding APIs are all heavily Objective-C/NextStep based and aren’t really all that unixy. We do have GNUStep as a base to use for that to an extent but I really don’t think the unix parts of Mac, are that helpful to porting complex user facing GUI programs.
