Black screen with mouse pointer after Apple logo on boot

[jakesDaddy]

Thanks, but the InjectIntel is definitely already checked in my photos (it's just that it's the world's smallest checkbox, especially on my 4K monitor, the photo just doesnt show it!). I assure you though, it is definitely ticked.

However, just to be 100% sure, I've just been and retried the 0x59128086 and 0x59120003 settings, both with and without InjectIntel checked.
Without InjectIntel checked, the system does as originally reported - black screen with mouse pointer.
With InjectIntel checked and the 0x59128086 and 0x59120003 settings, I get the screen corruption.

In that case change the ig-p-id to 59120000

if changing ig-platform-id to 0x59120000 does not fix the back screen , I suspect your CLOVER/kexts/Other may not have the latest lilu.kext and WhateverGreen.kext.

OK, so changing ig-platform-id to 0x59120000 did not fix it - we are back at the original problem of black screen with mouse pointer. So, based on the 2nd half of your reply:

I suspect your CLOVER/kexts/Other may not have the latest lilu.kext and WhateverGreen.kext.

what do I need to check and how? I can mount the EFI partition by booting the 2nd disk and using Clover Configurator, so from there I can use Terminal or Finder to navigate to the CLOVER/kexts/Other folder. How would I know if I have the latest of these 2? Presumably I can just download the latest from somewhere and replace them (I'll keep the originals just in case )

• Yes , that is a good plan.
• From the links pasted here, you can download to that disk's desktop, the 2 essential files.
  https://github.com/acidanthera/Lilu/releases/download/1.2.7/1.2.7.RELEASE.zip
  
  https://github.com/acidanthera/WhateverGreen/releases/download/1.2.3/1.2.3.RELEASE.zip
• Similarly you can download and launch CCG .
• Mount the EFI of the System Disk with the problem black screen
• Go to its CLOVER/kexts
• Remove unwanted empty numbered folders 10.6 to 10.14.
• In kexts/ Other, copy and paste the extracted kexts
  • Make sure that it has all the kexts you need.
• Make sure drivers64UEFI has all needed files
• Make sure config.plist is edited properly

Sample CLOVER screen shots from a working GA-Z270X can be seen at https://www.tonymacx86.com/threads/...ming-i7-7700k-intel-hd-630-radeon5450.239427/

Thanks for all your help, but I still can't get this going!
Previously I only had lilu 1.2.3, so I've downloaded 1.2.7 of lilu and 1.2.3 of whatevergreen; and followed the instructions at https://www.insanelymac.com/forum/topic/334899-intel-framebuffer-patching-using-whatevergreen/ (as best I can!).
So, after installing the 2 new kexts and following the instructions re: config.plist edits, I have the following situation:

• the original (non-booting) installation now hangs at the Apple logo screen
  • if I add -v, I can see its doing the "Hash data from ME never returned, status = 1, doing retry x" loop. This is presumably because the instructions told me to remove -disablegfxfirmware
  • if I add -disablegfxfirmware back again, then I get the same old black screen with mouse pointer
• the 2nd SSD still boots, but interestingly now natively (and by default) boots in 4K. This is without the pixelclock patch and SwitchResX that I have on the original installation (these were installed a long time ago and fully operational so I dont think are related to the problems ?)

Given that I know a fresh install will work (as proven on the 2nd SSD), I'm kind of at the point where I am going to wipe the disk and start again. It's a bit inconvenient, but I can do it if necessary.
Before I do that though, is there any mileage in setting up a Mojave USB installation media, and installing Mojave over the top of my broken High Sierra build?
My thinking is that given that HS is broken, attempting a Mojave upgrade wont make it any worse! And now I have the latest lilu and whatevergreen kexts (which are documented as necessary for Mojave) already installed on the clover partition, it seems like I am in a good position to try it?

What do you think?

• Not a good idea to try upgrading macOS for failure to run a previous version.

• If you want to try and replace the EFI folder of your non- booting HS SSD with the one I can upload, please post back.
