ok thanks the hackintosh boot with no message osx not supported , but now after that it was rebooting after trying initialise igpu i think because after all load of text of verbose mod , there is some artifact who was poping in screen , and it reboot.
i precise i was trying to boot with usb key with your efi files but i select booting on opencore selection my last installation of macos with efi inside ( configurate with dgpu amd rx 580).
maybe the problem was that ??
i wanna go to try reinstall full system with your efi.
Many thanks for your reply
