Hi bro, I'm using the same card with you, sapphire 6900 XT special edition, and it makes a very loud coil whine noise somehow. And it only happens on macOS but not on Windows. Not sure if this issue is related to the power management of the graphics card or not. Are you having the same problem?I have a Sapphire Nitro+ 6900 XT OC and it works out of the box with no spoofing needed. Just an FYI. No SSDT-BRG0 table needed. Only a few of the newer cards need this. Some of the 6900 XT do report the proper Device ID...
I've recorded the noise and uploaded it here:
