Hey I have this system, but the i5-8400 variant. I'm assuming you're attempting to install Mojave? If so, the issues you are experiencing attempting to get into the installer are likely related to your UHD 630. I was only able to boot into the installer using fakeid 0x12345678 and I successfully installed Mojave, but I have so far been unable to get graphics acceleration working (only shows 7 mb).

Using that ID should get you to the installer (if you're using Mojave) but it may be less of a headache to just install High Sierra, just my two cents.

If all else fails you can try my EFI folder. It's directly from my installer USB.

thanks ill try it and let you know if it works i posted i like that could help you fix you GPU problem but they removed it so see if this can help . maybe you can use google to find the post

Coffee Lake doesn't have it's own Framebuffer as of 10.13.4, but what we can do is use the Kaby Lake Framebuffer by inserting the Device ID's of UHD 630 0x3E918086 for i3 and 0x3E928086 i5/i7 after which you can set as your FakeID in config.plist. By connecting these Device ID's to the Kaby Lake Framebuffer this will unlock graphical acceleration for the Coffee Lake i3's it can also be used for the i5 and i7 for acceleration. I'm actually using this method for all my Coffee Lake CPU's as it also gives me Hardware Encoding with Shiki.kext

The Kaby Lake Framebuffer may be overwritten each update and therefore you will redo this patch with each update i.e. going from High Sierra 10.13.3 to 10.13.4.

This patch is applied through the Terminal App since the plist files of the Kaby Laker kexts we need to inject the Coffee Lake Device ID's into aren't directly editable in Finder. This should only take 2-3 minutes to perform.

Appreciate it, but I don't believe that method would be valid for Mojave 10.14

0x12345678 should be in intelGFX ?
