Unfortunately, I couldn't figure out the problem on my 9470m laptop. I did the installation from the beginning. I injected Edid and dropped my oem but it didn't work. This model does not have an external graphics card, the intel hd4000 has a 2GB graphics card. It stands on the black screen after it is turned on. If I open and open the lapton cover, the cursor appears on the screen. But the black screen remains. It turns on smoothly via usb, but does not open on hd. I keep Hd and usb's efi folders the same.
I started with usb and then got the report.
install macOs 10.12.6
report file added. what can i suggest.
I checked the bios and rearranged the config.plist file with the PlistEdit Pro program, but I still have the same problem. I would recommend that you try the smbios ids for this laptop.
