    Yes i change it to Boot Once also, no this is my first time trying it on this built. However, i know is not big sur because i have use it on my Mac Pro 5,1 with open core as well, also on a 2019 macbook pro. What’s is funny is that the Apollo Twin works like a charm.

    Big Sur 11.6.7 UAD Apollo FireWire Silver Rack With Thunderbolt 2 Option Card Bios F9J This is my first time trying this setup. UPDATE: It does recognize my Apollo Twin Thunderbolt 2 but not the rack. I AM USING Apple USB-C to Thunderbolt 2 adapter (TB3 to TB2)

    @CaseySJ how you doing my friend, first of all, thanks again for everything you do for the community. I just want to say that you had helped me before and once again I'm in the need of your expertise, lol, sorry about that. I have done this exact setup before but for some reason it won't work...

    @CaseySJ quick question my friend. Is there any guide on how to downgrade BIOS flashing the chip method? I don’t know if you understand where I'm going. (From F9 to F9i) xD
