I enjoy my FPC programming on the Mac these days, but that is, of course, thanks to the FPC team, not Apple. I even enjoy Cocoa programming now that I don't have to use Objective C!
But for the challenge, that doesn't matter, I don't use any (visible) Cocoa at all so far. I work though GLUT. I intend to switch to my own Cocoa-based API when I have time, but that won't happen until after the challenge has ended. Not much time left but I am still trying.
