Sharing Asus z390-i 9900K Vega 64 DW1560 Opencore(v0.55) based EFI
what works: everything(booting faster than clover)
what need to do: add ur own PlatformInfo in config(iMac Pro)
PS: due to personal reason, usb device cannot wake up macOS, only the power button could do it.
Thanks to ModMik's thread, all Bios settings and EFI are from his thread.
Every thing works fine, handoff wifi bluetooth 100% working.
SAPPHIRE Vega 56 BIOS had been flash to Vega 64.
Memory had been modified to 16G * 4, if not, system cannot boot.
Intel i9 9900k...
Try to use USB-A, my EFI didn't open USB3.0 mode of the USB-C port. Or you can make your own SSDT. Here is the number of the ports, which will save time for you. One more thing, HS02 is USB-C, you can add SS02 to your SSDT.
