There is no copyright issue in this case, no Title 17 violation. It is a licensing contractual dispute between Apple and ANYONE using OSX on a non-Apple labeled computer. Perhaps I've missed something in Title 17, show me the exact section and I will take a look at it.
All good points by you and TechHistorian. While I can see clearly your point on this being a contractual EULA issue, I happen to agree more with TH on this one, and here is why: the fundamental question is whether Apple, or any other device maker, has the right to distribute the software that comes with their device in whatever manner in which they choose. I can see a court case on this going all the way to the top, due to just the issues you have been debating, but at the end of the road, even it goes all the way to the Supreme Court, eventually, they will see the parallels between this and the rights of a copyright holder to control distribution, and rule in favor of Apple.
