You can get a list of all of them...

Install Hex Fiend.
In Terminal:

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

In Hex Fiend, search for a known ig-platform-id, for example, 0x59120000 is hex search for '00 00 12 59'
Each ig-platform-id is 184 bytes (in this kext and SKL).
It helps to expand the Hex Fiend window to 23 columns (need a big screen, 184/4/2=23), because then you can see each ig-platform-id lined up vertically (every other row).
You will find the table starts with 0x591e0000 and the last is 0x591b0006. The 0xFFFFFFFF signifies the end of table.

That post has nothing to do with "fakeid".
AAPL,ig-platform-id injection is not the same as device-id injection.

So this would not help in my case here?

No idea what you mean by "this".

Is it only ig-platform-id I need to change?
I've tried 59120000, 59160000, 591b0000, 59260000, 59260002, but no avail.
Thanks.

Thanks.

Without PR files that represent the attempt, I cannot verify or help.
I think it was 0x59260002 that was providing success. You should read recent posts to confirm.
