"The gist of the hint I was given is that the disk-level hacks CL uses for software protection in P5 are unsupported by Apple" This is completely untrue. CL does not use "disk-level hacks" for p5 protection, and I've been in contact with the CL team about macintosh. The reason it's delayed is the exact reason stated on their site. OSX has introduced a number of engineering, and standards changes which are hard to learn, and support. "Apple offered viable substitute protection plans and CL isn't interested in those alternatives." Har, I know it's fashionable to spread misinformation, but Apple hasn't been in contact with CL over protection plans at all. where did you find this stuff?
