No signal at boot

[danizichi]

Hi, I installed macos sierra on my rig:
cpu: q8400
mobo: asus p5ql/epu
ram: 8gb ddr2
gpu:rx460

After installing the os, I booted from usb, I started macos from hdd and the apple is popped up with the loading page. After having finished loading, I no longer receive a video signal. I am able to boot the operating system only in safe mode but I can't use multibeast. Can you help me??

I am attaching the log, sorry for poor quality, but the last screen appears for less than a second.

Looks like a Graphics issue.
RX 460 needs RadeonDeInit or Lilu and WhateverGreen kext

Use RadeonDeInit!

Did you mount the EFI partition of your USB installer?

I m not able to do that on windows... I put a new version of clover on another pendrive. Now after loading i have a black screen but not a no signal... if I wait a bit, the monitor goes into no signal, when I press a button on the keyboard, appears the arrow on the black screen.

So from where did you download macOS Sierra?

I solved! solution: I put the latest version of clover on pendrive, with ubuntu I copied the kext that had put unibeast on the first installation pendrive, I followed the guide you proposed. And I used multibeast. Now I have only a few problems with the connection and the audio. To install kext, do I need to add them in Efi / clover / kext / other? why the connection work when I boot macos from usb? Thank you so much.
