I have been trying to fix this error for the past day with no success, I have followed dortania guide for coffee lake plus laptops.

I have tried editing the config file multiple times every time from scratch. downloaded all the relevant files and still can't boot to installer i am using the latest OpenCorePkg 0.6.8.

I have also disabled secure boot in the bios settings and changed the SATA mode to AHCI.


P.S. yesterday i have been also getting the pci configuration end error.


Here's a link to my EFI folder:



System Specs:

Laptop - Lenovo legion y740

CPU - i7 9750h

GPUs - rtx 2070 maxq(disabled in the config file), uhd 630(enabled in the config file)

RAM - 32GB

SSDs - NVME ssd sn720 512gb, SATA ssd crucial mx 500 1tb.


Any help will appreciated.

VirtualSMC plugin for moment

You mean to remove the VirtualSMC kext?

disable it for moment. virtualsmc.kext still required

Tried with the kexts you suggested, removed those SMCProcessor.kext, SMCSuperIO.kext and still the same issue, it freezes at the same point. BTW i forgot to mention when i was getting those errors the laptop will freeze and the usb light indicator will stop working same as before.
