Sir, my equipment is MACOS 10.14.6/Motherboard Gigabyte BKi7HA-7500/BIOS F12/CPU Intel i7-7500u/Intel HD 620
Following this article, It sounds perfectly, but I cannot control the volume at all, including volume up/down and mute,and the HDMI output will be disabled whenever I reboot, replug the HDMI is the solution.
And the framebuffer was patched perfectly by check the system information (32MB becomes 2048MB).
All I do was using the kextbeast to install whatevergreen.kext and lilu.kext. btw, I finally found it out that WEG means whatevergreen.
Then using the clover configurator to edit the efi/efi/clover/config.plist/device/properties, to inject pciroot(0x0)/pci(0x2,0x0) with aapl,ig-platform-id, framefuffer, unifiedmem, etc.
And inject kext to patch to whatevergreen find 03060800 00040000 11000000 replace 03061200 00080000 06000000.
After reading once and once again, I can't figure out the solution. I really need a suggestion.
