HD4600 causing panic with device-id 12040000 (opencore) catalina

[sebadier]

Hi everybody,
I've trying to get around this for days now:
Setup:
Lenovo T540p
Intel HD 4600 / GT730M
boot-args: -v keepsyms=1 debug=0x100 -wegdbg -wegnoegpu

When I set the device-id of the IGPU to 12040000 as suggested by opencore vanilla guide and many other sources around the web, my machinge gets stuck just before loggin in.

weg: configread16 IGPU reported 0x0412 instead of 0x0416
weg: configread32 IGPU 0x00001000 at off 0x00, result = 0x04168086
iokit: getOSData device-id has 412 value
weg: configread32 reported 0X04128086 instead of 0x04168086

gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0

When I set a different device-id, I can boot normally, but then my IGPU is not being recognised properly and I have only 7mb of VRAM.

So, it would be great if any of you have ideas about this.

Have you been able to solve it? I am struggling with this also.

You need to choose the correct device-id for your cpu igpu. I had the same problem. Take a look at .... https://github.com/dortania/clover-...repare-install-macos/display-configuration.md

I Solved my instalation and boot glitches using those flags bellow, dont ask me why, I just copied my old config.plist from my old mojave installation and everything works like a charm.
Tell me if it works for you too, good luck<3
