Spy chips are: * Intel CPUs after ~2008 * AMD CPUs after ~2013 * Arm CPUs (not sure when they started the trustzone stuff but likely around 2013 since AMD uses trustzone) I believe IBM Power9 chips are spy chip free, but not sure about the successors. Anyway, the question is about Apple chips. Web searches are lousy these days. I find nothing to confirm or deny the presence of management engines in Apple (Motorola?) CPUs. Intuitively, I don’t think it would make business sense for Apple to do that because a majority of their customers are non-corporate individuals (unlike intel). OTOH, if that were sound logic then it would seem to contradict Arm chips which are also largely bought by non-corporate individuals. If anyone knows plz mention it here, ideally with a source. Thanks!
