I re-installed macOS high Sierra success with invalid ig-platform-ids ( to passthough installation step), and valid fake id for Intel HD 4600

I boot MacOS on HDD success



When I got Desktop of high Sierra

I installed 2 kext in to /S/L/E and EFI/CLOVER/KEXTS/OTHERS
- FakePCIID_Intel_HD_Graphics.kext
- FakePCIID.kext

I've tried reboot with valid ig-platform-ids( and with inject EDID=true ) but still get "System restart while booting"


this is Problem Reporting I collected
the file RehabMan.zip I collect follow your guideline ( but in case using invalid ig-platform-ids to able to boot into desktop )
the clover.zip the config with F2 and F4 in clover screen ( with valid ig-platform-ids, then got system reboot )
included command output as require of your FAQ

Please help me,
It took me more than 1 month to try to have Intel HD graphic full performance

Did you try safe mode? (safe mode will exclude the accelerator kext, but will allow the framebuffer kext).
And all kexts you need should be installed to the system volume.
Maybe you are overlooking an important BIOS setting.

How to boot in safe mode


My BIOS settings are below:


In these images setting
Intel (R) Virtualization Technology (Enable)
Intel (R) VT-d Feature (Enable)

I tried with disable both of them, but there is no change.

How to boot in safe mode

It is available from the menu in Clover, accessed by pressing the space bar.

My BIOS settings are below:

As per guide:
- fast boot should be disabled (you have "quick" enabled)
- network boot should be disabled
- Intel Rapid Start should probably be disabled
- VT-d should be disabled
- wake on lan should be disabled
- UEFI network stack disabled
- UEFI PXE disabled

 

[RehabMan]

Boot mode has no Disable only quick and Diagnostics
I changed to Diagnostics

network boot also has no Disable
I selected Other CD


Intel Rapid Start => Disable


VT-d => Disable



- wake on lan should be disabled
- UEFI network stack disabled
- UEFI PXE disabled




Save all these settings
then boot => there is no change, System still restart

I boot in safe mode boot,
It seems output more log, but no change, System still restart

here is the log of safe mode boot ( included F2 F4 at clover screen )

Try other ig-platform-id values.

Try other ig-platform-id values.

It seems go back using invalid ig-platform-id => system can boot, but graphic only 7MB
( tried with 0x12345678 or 0x11111111)

Extract all from framebuffer kext and try each one.

Extract all from framebuffer kext and try each one.

where I can get framebuffer?
I didnot put framebuffer kext into kexts folder, Do I need to put and try again

Is there any way to debug my problem?

Install Hex Fiend.
In Terminal:

open -a "Hex Fiend" /System/Library/Extensions/AppleIntelFramebufferAzul.kext/Contents/MacOS/AppleIntelFramebufferAzul

In Hex Fiend, search for a known ig-platform-id, for example, 0x0a260006 is hex search for '06 00 26 0a 01'
Each ig-platform-id is 112 bytes (in this kext and KBL).
It helps to expand the Hex Fiend window to 14 columns (need a big screen, 112/4/2=14), because then you can see each ig-platform-id lined up vertically (every other row).
You will find the table starts with 0x0c060000 and the last is 0x0d26000f. The 0xFFFFFFFF signifies the end of table.
