hi I have tried you. you have I tried Olarila Sequoia 15.5 24F74
and efi file EFI.Opencore.Desktop.CoffeeLake I have put it on USB with balenaEtcher-2.1.2.Setup
and have updated the efi with EFI.Opencore.Desktop.CoffeeLake
when I boot up on usb and select usb, the olarila bootloader appears
it starts to lag and the screen also goes black both with hdmi and displayport what's wrong it's a graphics driver it's missing
