Well I've got quite far with it. I don't have anything in S/L/E.
I have BrcmFirmwareData, BrcmPatchRAM2, FakePCIID_Broadcom_WiFi, USBInjectAll and FakePCIID all in EFI/CLOVER/kexts/Other/
Bluetooth works for keyboard and trackpad and it shows that iPhone and Watch are paired and connected in System Information. AirDrop works in both directions. But I've only managed to get Handoff working in one direction. Items open on the Hackintosh show up and deliver payload to the iPhone, but iPhone never delivers its Handoff payload to the Hackintosh.
I can enable Auto Unlock for my Watch successfully, but when it actually tries to unlock with the watch it just times out. I suspect this is related to the Handoff issue I just mentioned.
