Mac OS X Kernel Source Now Closed

*Extremely* old news.

Also, "Mac OS X" has ALWAYS been proprietary. It's sensationalistic and shoddy journalism to say that "Mac OS X is now closed". Mac OS X has ALWAYS been closed. It's Darwin that has been open. And "Darwin" is more than a bootable OS: Darwin is Apple's open source strategy AND an OS; but the usefulness has always come from the open source components of the OS, not the usefulness of Darwin as an OS itself. Darwin's usefulness as an OS is, shall we say, "limited" at best, and always has been.

This has been beaten to death on the darwin-dev list, and there is no new information. Apple has taken no new recent action whatsoever, and in fact, the most recent action is that it has opened up more source code in the x86 tree, not less. Indeed, all of the traditional Darwin source with the notable exception of the kernel itself:

The thing that's not open in the x86 tree is xnu (the kernel), and it's not possible to create a fully bootable binary x86 Darwin OS, as it is for PPC. In the Darwin/OpenDarwin community, this has been discussed for months.

In fact, this article by Rob Braun (formerly of Apple, and a member of the OpenDarwin core team) was published in February 2006: http://ezine.daemonnews.org/200602/apple.html [daemonnews.org]. This was then covered on slashdot, to which Rob issued this response: http://www.opendarwin.org/~bbraun/slashdot_respons e.html [opendarwin.org]. These two discussions cover the issues very well.
