You would need to provide details on what you're doing.
Note: You should stick to the ig-platform-ids that have patchable (concrete) data values.
Yes.
I am under the process of upgrading the laptop to High Sierra GM.
I have successfully installed High Sierra. Things that broke from Sierra 12.6:
*
Trackpad in SysPreferences I had an old copy of VoodooPS2Controller. Working great.
* Brightness Adjust (I removed the kext patch and SSDT to clean up)
But more importantly, I cannot boot without platformid 0x12345678 . My old fix seemingly does not work anymore.
When I try platformid 59160000 I get a KP very early in the boot process. If I try 591b0000, with corresponding patch values
Find: 01030303 00006002 00005001
Replace: 01030303 00003001 00009000
I get the same KP. Both of these are tried after booting with 12345678 and rebuilding cache.
I have opened AppleIntelKBLGraphicsFramebuffer in HexFiend and confirmed that my old numbers are still valid. It does match on two sections though, is that a problem? I
have not confirmed the values for 591b0000 in the kext, I am using the ones from you at

I hope this gives a clearer view of my problem. If I need to provide other details please tell me.
