IIRC these services are tied to a specific MAC address (from real Macintosh hardware) that has to be whitelisted.

Edit: and it sounds like non-apple wifi cards may only be supported by older OS versions. Since Apple knows the exact configuration of every computer they sell, their OS only supports specific hardware configurations and doesn't have generic drivers. If Apple only sells macs which have a specific proprietary Wi-Fi card integrated on the motherboard than they'll just make it so only that Wi-Fi card is supported. This is similar to the fact that Apple stopped shipping hardware with Nvidia cards, so eventually Nvidia driver support just ceased to exist.
