[Apple] has stated before that it doesnâ€™t cooperate with secret agencies and doesnâ€™t build in backdoors in their hardware and software."
IDK about Macintosh, but Apple's hanheld i-Things have been known to contain backdoors, such as the one that allows Apple to delete the users' apps whenever they want, for years. Also, if the US government wants to (mis)use those backdoors, I don't know if Apple has any say in whether the govenment can/can't do so. Also, according to this GNU.org article: "Apple can, and regularly does, remotely extract some data from iPhones for the state".
I do wander if Apple will be able to continue to oporate those Chinese sweat shops responsible for manufacturing those i-Things.
