Well, so Apple is managing a plist (within a kext) which is supposed to allow certain (3rd party) kexts to be loaded (without signing) and all of these "hack kexts" are in that list? Hmmmmm! Now that is interesting, but I am still not sure what that means. I really cannot imagine that Apple sort of inofficially supports Hacks by this way ... but why is all this stuff in there then? Because I think it would be more typical for Apple that this list is made for lockdown and exclusion of hacks, and not for (even unofficial) support.
Also, in a follow up comment to the article I mentioned above, the original poster stated that: The thing is that Apple has more on their sleeves but that info isn’t even shared, but I have said too much already – since this info was meant to be confidentially – so I just let them be what they are… uninformed.
I don't know if he is just making this up, but it sounds not completely uncredible - and quite mysterious - to me.
