Osxfrench Posted December 10, 2021 Share Posted December 10, 2021 Thanks @Lorys89 but it didn't work for me. I used your EFI with an update from BIGsur. The startup is ok but the system is slow, the usb ports, the wifi does not work My config is not the same , I have a Dell E7280 but i5-6300 (skylake) with a HD 520, 16go ram. Is it possible to build a configuration with this base? thanks Link to comment Share on other sites More sharing options...
Osxfrench Posted December 12, 2021 Share Posted December 12, 2021 I am on Monterey 12.0.1. My attached configuration with opencore (0.7.6) boot report, my pci device and my EFI. What doesn't work: Wifi (edit: ok with AirportItlwm.kext) Touchpad BT Sound (Edit: i try VoodooHDA or AppleALC but doesn't work) If anyone can help me thanks EFI.zip Link to comment Share on other sites More sharing options...

Osxfrench Posted December 13, 2021 Share Posted December 13, 2021 Thanks for your help @Baio77 I'm a newbie. I tested your EFI in usbkey and it didn't start. Stuck on "OC: Driver AudioDxe.efi at 0 cannot be found! Hating on critical error" You will find the file generated by the Efi Debug opencore-2021-12-13-205357.txt.zip Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 13, 2021 Moderators Share Posted December 13, 2021 @Osxfrench Just add AudioDxe.efi to drivers folder or disable it in the config.plist file. Not use unless you want to enable boot up audio. Link to comment Share on other sites More sharing options...
Osxfrench Posted December 13, 2021 Share Posted December 13, 2021 Thanks @Jake Lo I added the file in driver and it started @Baio77 I added Efi debug on usb I started with but there is nothing inside EFI.
