Sorry for my bad english I got a bcm943460mc wifi card, when i plug it in mac pro 3,1, machine can't boot, logic board errb led lighting, i press reset button, then both errb and erra leds lighting, pull out this card or install another wifi card, system boot normally, and i try to install this card in pc laptop and desktop, they both work correctly. is there any blacklist in mac pro efi firmware? i searched macrumors, there is a success report about this card, links here. but in that thread, it's been installed in a mac pro 5,1 system, maybe it is not compatible with 3,1? need help, thanks!
