I’m trying to switch from Clover to OpenCore (0.6.6), and I’m running into trouble around graphics configuration on High Sierra 10.13.6.
Because my BIOS (version F6) doesn’t have the “above 4g decoding” option available, I’m only able to boot with the ncpi=0x2000 or ncpi=0x3000 boot args, but I can’t get GPU acceleration to work.
WebDrivers are installed but he GPU’s show up as “VGA enabled devices” in System Information > PCI.
Is this a hardware mapping issue?
Whatevergreen issue?
4g decoding BIOS issue?
Appreciate any help!
