As far as I know while the Management Engine is in all chipsets that accompany Intel CPUs, Apple never shipped any AMT enabled firmware. This is the more exposed component.
I don't think they've ever used the Intel NIC hardware either, wired or wireless.

See the "EFI" section.
Exploiting the ME is possible even without AMT but it definitely raises the bar in the sophistication of the attack.
The me_cleaner tool might do a good job in disabling the ME in most cases but since it's doing it by removing components from the ME FW it probably doesn't work with every OEM implementation.
