AFAICT, the multicast bit is only required to be set on random MAC.

I don’t understand.  Are you saying that _find_mac() should return whatever random MAC is found first, as the original code does?  That doesn’t seem right either, since as the MacBook Pro case shows, it’s entirely possible to get a MAC address that is the same on every single laptop.
