Administrators Hervé Posted March 27, 2017 Administrators Share Posted March 27, 2017 What are the laptop specs? If it's dual GPU, you should be able to disable the discrete GPU (dGPU) through a SSDT patch. This assumes your integrated GPU (iGPU) is supported by OS X of course... You'll have to extract your raw ACPI BIOS tables and post them. With Clover, you can do that by pressing F4 at Clover main menu. All extracted tables will then be saved to Clover/ACPI/origin folder of your EFI partition or EFI main folder, depending on your Clover installation.
