AirPods and AirPower: Everything We Know
Mac OS X Darwin x86 Kernel Still Open?
Just to be clear, Tom Yager was *speculating* about why we have -- so far -- not released the source code of the kernel for Intel-based Macintoshes. We continue to release *all* the Darwin sources for our PowerPC systems, and so far has released all the non-kernel Darwin sources for Intel.
Nothing has been announced, so he (and everyone else) certainly has the right to speculate. But please don't confuse "speculation" with "fact."
