Replace the FakeSMC file. RX460, RX560 can works good.
Starting own thread to try and fix this issue I am having.
I'm running an HP 8300 which has been very stable using onboard HD4000 graphics. With the move to 10.13.4 I upgraded to an RX560. This is working well with two monitors EXCEPT for the significant issue whereby both screens go black and cannot be turned back on. This seems to be random, and the computer continues to e.g. play music. I have not find a way out except to hard reset i.e. use the physical power button.
Sleep on the computer works properly.
Displays turn off and wake works properly.
I followed @pastrychef excellent guide and have enabled the Intel HD4000 onboard graphics in order to get Quicksync (which is working according to MacX Video Convertor Pro). I have also been following along with this thread but no-one seems to have the same issue, except this person.
I am first trying to get graphics on the RX560 working stable. I will then look at HDMI/DP audio.
Attached is config.plist and below my /Library/Extensions folder. Let me know if anything else would be useful to troubleshoot.
Any suggestions how to get this back working stable? Thanks in advance.

iMac13,2 is correct for your system. I am using the same for my i7-3770K.An update. I ran with the HD4000 for a few days, and it was 100% stable. I've just put the RX560 in along with (per this thread)
I also added to my Clover config (as per this thread)
- Lilu
- IntelGraphicsFixup
- WhateverGreen
I'm testing the stability now, first with with a single DP monitor.
- rename PEGP to GFX0
- 0x01620007 in the "ig-platform-id" section
Audio over DP worked without having to do anything (I didn't have any audio setup on the 8300 i.e. analogue jacks are no setup).
BruceX is back at around 33 - 35seconds.
Reviewing this thread my HD4000 shows up in iStat menus, VDADecoderCheck says "GVA info: Successfully connected to the Intel plugin, offline Gen7, Hardware acceleration is fully supported".
However if I run the Intel Power Gadget I can't get the Processor Graphics frequency to move from 0.35 i.e. 350mhz. If I play the Sony Camp 4k demo.mp4 then video stutters and no movement on the graphics frequency. I know this machine isn't the newest but with an RX560 I expected to be able to play 4k video?
I'm using the iMac13,2 system definition. I haven't flashed my card (and hope I don't have to!).
Hopping over here to this thread to check in on this issue.I have made progress...I disabled the onboard graphics in the BIOS, rebooted and so far have not had any crashes. It's only a few hours so far, but with graphics enabled it was crashing within 15mins. Will keep things updated...
Attached are my config.plist and IOREG outputs from a boot with RX560 installed and HD4000 disabled. I'm not really sure what I am looking at in IOREG..Post your config.plist and IOREG file.
Couple of ideas. Have you tried running Windows with the RX560 installed to rule out any hardware related issues? You could also try removing any kext that ends in Sensors.kext and see if that has any effect. I know those can cause problems in certain scenarios.Ideally I would run the RX560 + HD4000 (for quick sync).
- If I run HD4000 only it is stable.
- If I run RX560 + disabled HD4000 it still crashes - just hangs (no black screens any more) but not as often as with HD4000 enabled.
- If I run RX560 + enabled HD4000 I get regular crashes.
@HackaShaq the crashes (it just hangs, or sometimes reboots, or sometimes has a black screen) are not repreoducable but they are regular. The only common thing is I have to be using the machine. If I just leave it on, its fine. Sleep/wake etc. If I'm using the machine (e.g. web browsing, listening to music) thats when I end up with issues. I am running APFS but don't see any indications that is the issue.
Looking at the system log, the common thing just before each hang is related to iTunes "iTunes[286]: tid:4f0b - Can't handle disconnect with invalid ecid" or "iTunesHelper[451]: tid:e03 - Can't handle disconnect with invalid ecid".
I have removed Whatevergreen as per comments above.

These are the kexts I have installed:

A clean macOS install is a good idea. Add in 3rd party kexts one at a time and see what happens. You can delete the Sensors.kexts and reboot they are not mandatory.It came from a working machine but that will be a test soon. I have a spare HD so will use that. I may even try a clean MacOS install to see if it still happens.
Re the sensors.kext can they just be removed (as in deleted) - they don't need replacing with newer versions etc?
In regards to your kexts in other, what about removing the following from EFI/CLOVER/kexts/Other:These are the kexts I have installed:
