    I have noticed that I cannot change the MAC address on my Yosemite 10.10.5 workstation to certain MAc addresses like 35:60:90:19:ef:90.

    Does anyone know why this occurs? I know I should be able change the MAC address to any value and this condition seem to occur recently maybe 4 months or so.
