Administrators Hervé Posted November 18, 2020 Administrators Share Posted November 18, 2020 It doesn't look like you used the E7x70 pack for Sierra. Using Clover Configurator app, in Devices tab, add the following property injection to your iGPU device located at PciRoot(0x0)/Pci(0x2,0x0) : AAPL,ig-platform-id 00001B19 DATA I'm not sure about that injection you have that sets port count to 4. Remove it unless required. Link to comment Share on other sites More sharing options...
