Black Screen with MacPro 6,1 or iMac 15 or iMac 17 System Definition

[shawnferry]

Using iMac17,1 and my profile config and thunderbolt passthrough I get BIOS and boot messages until I eventually fail at the black screen. I have ssh access in that state but screen sharing doesn't work.

I think I've tried most all of the solutions in this thread and some others but I may have missed/misunderstood some or combined them in strange ways.

(A) Baseline state; no extra kexts, no extra ACPI patching.
| +-o PCI0@0 <class IOACPIPlatform$
| | +-o AppleACPIPCI <class AppleA$
| | +-o pci8086,191f@0 <class IO$
| | +-o PEG0@1 <class IOPCIDevic$
| | | +-o IOPP <class IOPCI2PCIB$
| | | +-o PEGP@0 <class IOPCID$
| | | | +-o NVDAHal <class IOS$
| | | | +-o NVDAgl <class IOSe$
| | | | +-o NVDA,Display-A@0 <$

(B) I've tried only NvidiaGraphicsFixup, but then the drivers don't match and get unloaded
| +-o PCI0@0 <class IOACPIPlatform$

| | +-o PEG0@1 <class IOPCIDevic$
| | | +-o IOPP <class IOPCI2PCIB$
| | | +-o PEGP@0 <class IOPCID$
| | | | +-o .Display_boot <cla$

(C) I've tried only renaming PEGP to GFX1 via ACPI patching

| +-o PCI0@0 <class IOACPIPlatform$
| | +-o AppleACPIPCI <class AppleA$

| | | +-o GFX1@0 <class IOPCID$
| | | | +-o NVDAHal <class IOS$
| | | | +-o NVDAgl <class IOSe$
| | | | +-o NVDA,Display-A@0 <$

I hope I'm just missing something silly any help would be appreciated.
Thanks

I'm not having any luck with that fix and iMac17,1

Use iMac 14,2 instead of 17,1.

Can you boot with nv_disable=1? If not, you have another bigger issue. pastrychef confirmed that the Lilu/NvidiaFixup kexts worked for iMac17,1 with his Z170 system.

Use iMac 14,2 instead of 17,1.

I did try that it didn't seem to change anything.
I believe that I'd rather use 17,1 for the much closer match to my hardware.

Before I got around to posting this reply I got it working. I did a full rebuild to make sure I knew the exact starting state. It seems like EmuVariable wasn't storing nvda_drv in nvram on shutdown. After I added the needed XML to EFI/nvram.plist it seems to work as expected.

It also seems to persist variables now only if I have set force mount selected ESP, maybe I missed something in EmuVariable usage/setup?

Edit: Also I've set "Save NVRAM: Always"

Thanks

Adding nvda_drv=1 to your boot args in the clover config will cause the web driver to load regardless of pref pane settings or if nvram is non-persistent.

I updated to macOS Sierra 10.12.4 today.

I'm using iMac17,1 system definition with Lilu.kext + NvidiaGraphicsFixup.kext. However, some of the icons in Safari were distorted with the latest Nvidia web drivers.



When I removed the Lilu.kext + NvidiaGraphicsFixup.kext and used ADGPfix 1.3 instead, everything returned to normal.

I did not notice that on my setup with iMac15,1.

Weird... The two kexts worked in 10.12.3 but caused the distorted icons in 10.12.4.

After removing the two kexts, I enabled the PikeRAlpha Clover patch so that I could see to run the ADGPfix 1.3. After running ADGPfix 1.3, I disabled the PikeRAlpha Clover patch and re-enabled the HD 530 and the icons were good again.

FYI, just using the boot arg "nv_disable=1" should allow you to boot with basic graphics to perform tasks like that.

I've tried to get the Nvidia card working, but whenever I change the graphics default in my BIOS to the Nvidia card, I get a distorted (wrong resolution) clover screen, followed by a boot to the point where the screen flickers during an Intel HD graphics boot, followed by a blank screen by system control. I know the system is working because I can, without seeing the screen, log in, open the terminal, enter sudo reboot and my password, and wait. The machine proceeds to reboot. I tried both solution #1, and solution #2 with no luck. I haven't tried #3 as I don't want to disable SIP, or #4 as I'm using the iMac 17,1 definition.

I've attached my config.plist with solution #1 implemented. Any suggestions?
