Moderators Jake Lo Posted July 8, 2021 Moderators Share Posted July 8, 2021 The error occur way above this message, if you could capture that in a video, it'll be more helpful. What type of drive does the system have? Did you check to see if they are Apple compatible as some models like NVMe Samsung PM981, PM981a, PM991 are not compatible.

VRdP Posted July 8, 2021 Author Share Posted July 8, 2021 Hello @Jake Lo!

Moderators Jake Lo Posted July 9, 2021 Moderators Share Posted July 9, 2021 Disable /delete VoodooI2C.kext/Contents/PlugIns/VoodooInput.kext in the Config file There's already another under VoodooPS2Controller and it's causing a conflict Link to comment Share on other sites More sharing options...
Mihari Oyama Posted July 9, 2021 Share Posted July 9, 2021 (edited) Remove VooodooI2C.kext and VoodooI2CHID.kext Re-snapshot your config and reset NVRAM before booting. Or using this updated EFI: - Dell E7490: https://1drv.ms/u/s!AmHnQsJK7vXsiVxAsbUX-ZV0l3BJ?e=O0K3XP - Dell 3390: https://1drv.ms/u/s!AmHnQsJK7vXsiVt-XJuLs4afWwxR?e=SUiKiq Edited July 9, 2021 by quynkk5 Link to comment Share on other sites More sharing options...
VRdP Posted July 9, 2021 Author Share Posted July 9, 2021 Hello @quynkk5 and @Jake Lo! Thank you both very much for your help. I tried the second version of the 7490 EFI shared by @quynkk5. This time it did boot onto the OS Recovery, but a couple of strange things happened: 1- When opening the Disk Utility for erasing the hard drive, even when I click on View - Show All Devices, my hard drive is not shown. 2- The trackpad does not work. However, if I connect an external USB mouse, it works perfectly. 3- Even when the trackpad does not work, if I wait for the keyboard lights to go off, when I put my finger on the trackpad the keys backlights turn on again. Any clue on how to fix 1 and 2 would be very much appreciated. Thanks in advance! Link to comment Share on other sites More sharing options...
Mihari Oyama Posted July 9, 2021 Share Posted July 9, 2021 Do you have NVME? BIOS setting to AHCI? Did you config your BIOS? Link to comment Share on other sites More sharing options...
VRdP Posted July 9, 2021 Author Share Posted July 9, 2021 Thank you @quynkk5, number 1 solved! Now installing using an external USB mouse. Any clue on how to solve 2 would be very much appreciated. Link to comment Share on other sites More sharing options...
Mihari Oyama Posted July 9, 2021 Share Posted July 9, 2021 You need to patch your touchpad/Touchscreen with VoodooI2C Link to comment Share on other sites More sharing options...
VRdP Posted July 9, 2021 Author Share Posted July 9, 2021 Thank you @quynkk5 I'm not familiar with patching with VoodooI2C... Is that a Kext that needs to be copied to the EFI/OC/KEXTS folder and then perform a Clean Snapshot of the config.plist with ProperTree? Link to comment Share on other sites More sharing options...
Mihari Oyama Posted July 9, 2021 Share Posted July 9, 2021 Yes. You can use OpenCore Configurator instead of ProperTree. Place VoodooI2C.kext and VoodooI2CHID.kext, make a clean snapshot but DISABLE THIS KEXT VoodooI2C.kext/Contents/Plugin/VoodooInput.kext Otherwise, you can follow Olarila I2C Patch Tutorial: https://www.olarila.com/topic/5644-enable-i2c-trackpad-voodooi2c-not-a-guide-not-really/ and, did you try my EFI on Dell 3390 :D?
