Homekit WAC2 can Not be supported on mac OS 10.13.4

I am using the ADK 1.1 to develop the Homekit PAL modules, I noticed that WAC2 function requires iOS 11.3 or later. But I wonder that if WAC2 can be supported on mac OS 10.13.4. I have tried on my Mac mini(late 2012). But It does not work. So can anyone give me the answer if the WAC2 can be supported on mac OS 10.13.4? Thanks
