I don’t think informing people about ways to do things that go against software licenses violates the license.
Also, following these instructions doesn’t necessarily violate Apple’s license. You can run Linux on Apple hardware, and install Mac OS X on top of it, can’t you?
Finally, IANAL, but software licenses likely aren’t enforceable to consumers in large parts of the world (a shrink-wrap “take it or leave it” probably wouldn’t be considered an agreement between parties in many courts, and that’s what you need to call something a license)
