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!
