Administrators Hervé Posted January 22, 2022 Administrators Share Posted January 22, 2022 The iGPU properties injected in @Vonjy's Clover config are odd and contradictory: device location is incorrectly entered (though it probably works due to values being <10) framebuffer port count set to 2 yet there's a patch for a 3rd one This needs be revisited and configured with correct syntax and meaningful parameters: 1) iGPU device location PciRoot(0x0)/Pci(0x2,0x0) 2) iGPU properties AAPL,ig-platform-id 00001659 DATA device-id 16590000 DATA framebuffer-patch-enable 1 NUMBER framebuffer-stolenmem 00003001 DATA framebuffer-fbmem 00009000 DATA framebuffer-unifiedmem 00000080 DATA framebuffer-con1-enable 1 NUMBER framebuffer-con1-type 00080000 DATA // but this is usually to support HDMI audio, not HDMI per sé 3) SMBIOS Check whether MBP14,3 is more appropriate than MBP14,1.

Administrators Hervé Posted January 23, 2022 Administrators Share Posted January 23, 2022 Apart fom the weird value shown for iGPU subsystem id, all looks ok to me. What were your settings at the time you took this IOReg? Was HDMI monitor plugged in? Link to comment Share on other sites More sharing options...
