vPro isn't a CPU, it's a particular combination of CPU, PCH (southbridge), Intel NIC/WiFi, and AMT firmware. There's no evidence that Macs have AMT or vPro.
You're right about that. Intel's product lineup is a huge mishmash of optional features that no one understands and now it's going to bite them. (But not really, because what else are you going to buy? A Ryzen laptop?)
