Moderators Jake Lo Posted February 21, 2018 Moderators Share Posted February 21, 2018 Boot to Clover GUI. Hit F4. Continue onto OSX. Mount EFI partition. Compress and attach /EFI/Clover/ACPI/Origin folder here for patching Please also specify version of BIOS it's running currently. If you want to update to latest BIOS, please do so before doing the steps. If you don't know how to attach, see FAQ on my signature Link to comment Share on other sites More sharing options...

Administrators Hervé Posted February 21, 2018 Administrators Share Posted February 21, 2018 You should be able to do this through DSDT/SSDT patching where you basically permanently set the associated ACPI device (usually something like PEG0.PEGP or similar) to off. 1st check in IOReg which device corresponds to your nVidia dGPU which you'll find at address 0x00010000 (iGPU is located at address 0x00020000). Looking at your DSDT and SSDT-5-SaSsdt tables, it certainly appears that: your iGPU is device GFX0 your dGPU is PEG0.PEGP or PEG0.NVID Try this patched DSDT where I have: declared external method _SB.PCI0.PEG0._ON_OFF (defined in above SSDT table) declared a new _INI method to turn the PEG0 device off External (_SB_.PCI0.PEG0._ON_._OFF, MethodObj) // 0 Arguments (from opcode) Method (_INI, 0, NotSerialized) // _INI: Initialize { \_SB.PCI0.PEG0._ON._OFF () } DSDT.aml.zip Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted February 21, 2018 Moderators Share Posted February 21, 2018 Your Origin folder is missing the code to disable the Nvidia card since you disabled it in the BIOS. Clear the Origin folder first, then reboot to BIOS. Enable Switchable graphics. Boot to Clover, hit F4. I know you can't boot, that's okay. Reboot back to BIOS and disable Switchable graphics. Boot into OS X and attach the new Origin folder. Link to comment Share on other sites More sharing options...
