Any news here?

Yes, exactly.

I have a brand new MBP 15" with High Sierra 10.13.6 and onboard AirPort Extreme (0x14E4, 0x7BF) 802.11ac nic.

When I try to set a MAC address it jumps back to the default address immediatel.
When I try to apply a rule the whole top bar and every control element starts flickering. Seems like WIFISpoof and the Mac would fight for the right setting.

I also tried to set the address via ifconfig, disconnected the wifi network and even disabled the system integrity protection (csrutil disable) via rescue system – no success at all.

:huh:
