    Sorry for my bad english :confused:

    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! ;)

    You should read a little further in that thread where he says it's not working. It looks like it got black listed with an OS update back in the Sierra days.

    Best practice is to use BCM94360CD with appropriate 3,1 adapter. Because that card is what Apple used, it will have drivers and won't be black listed.

    If you're not using both built-in ethernet ports, the IoGear GWU637 was working for an old client's 3,1 machine. Have seen them under $35 on sale in the US recently.

    the problem is not uncompatible with macOS, seems it's not compatible with hardware. and i found a strange thing, yesterday i bought a BCM943602CDP, when i installed, it show me the same problem, errb led lighting.
