TechAndrew Posted November 9, 2021 Share Posted November 9, 2021 Attached is the image of where it gets stuck (no progress after 30+ mins). I am using the Big Sur OC 0.7.4 folder from the Dell Latitude e7470 guide. Any help is appreciated, thanks! Link to comment Share on other sites More sharing options...

TechAndrew Posted November 9, 2021 Author Share Posted November 9, 2021 It's a Dell e7470 with a Skylake Intel i7-6600U CPU (no discrete GPU, Intel Graphics 520), 16GB RAM. It was working fine on Big Sur with OpenCore 0.7.4. Link to comment Share on other sites More sharing options...

TechAndrew Posted November 9, 2021 Author Share Posted November 9, 2021 Some progress… I got it to boot thanks to your EFI, though without the keyboard and trackpad aren’t working anymore… I’ll see if I can replace the relevant kexts with my kexts.

Moderators Jake Lo Posted November 10, 2021 Moderators Share Posted November 10, 2021 Disabling BrcmBluetoothInjector.kext should fix it for Monterey or add the MaxKernel = 20.9.9 to if you're dual booting with Big Sur and below. Link to comment Share on other sites More sharing options...
TechAndrew Posted November 10, 2021 Author Share Posted November 10, 2021 Replaced the VoodooPS2Controller.kext with my copy and the keyboard and trackpad worked from there Link to comment Share on other sites More sharing options...
Baio77 Posted November 10, 2021 Share Posted November 10, 2021 Well every PC is case by itself due to the components installed, not knowing the trackpad model I put the kext for ALPS trackpad, but obviously it does NOT work for you, I would need the original ACPIs to see clearly on the type of trackpad ... You may need different kext than the ones you use right now. Use this EFI Debug in USB to extract the files I asked for and post them here, this if you want to improve the functionality of your Hack and as I asked already Ioreg is always needed as a verification tool EFI Debug 0.7.5.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 10, 2021 Moderators Share Posted November 10, 2021 It has an Alps PS2 touchpad version 8, there's no support for it that I know besides Dr. Hurts's voodoops2Controller with minimum functions and not very smooth. SkyrilHD has a version out with gestures but only supports version 7 1 Link to comment Share on other sites More sharing options...
