How legal is it to develop for Mac OS / iOS in a hackintosh?

Question

Law in IT

I write all sorts of programs and other little things for MacOS / iOS. At the same time, I use both the original MacOS (on a MacBook Pro when traveling and a MacMini in the office) and a hackintosh (the main home PC, because the toad is pressing to buy a MacPro / iMac, and decent power is needed). Programs are released both free and paid.
The question, in fact, is this: is the toad strangling me in vain, and can I end up with more financial problems than the cost of the aforementioned Boeings from the fruit company?
Well, the second question "there" - is it legal to use (on the same MacBook Pro) officially unsupported for a specific Mavericks model (the last officially supported is Mountain Lion, which does not know Xcode 6)?

Answer 1

Illegally from the word at all ─ I haven’t heard that it could be tracked, but in extreme cases, release builds can be assembled on apple hardware
