Administrators Hervé Posted August 10, 2023 Administrators Share Posted August 10, 2023 KBL HD620 with id 0x5916 is natively supported, even in Sonoma. FYI, if you checked the KBL driver in macOS 14.0 beta, you'd see the following iGPU ids: <key>IOPCIPrimaryMatch</key> <string>0x59128086 0x59168086 0x591B8086 0x591C8086 0x591E8086 0x59268086 0x59278086 0x59238086 0x87C08086 0x3E9B8086 0x3EA58086 0x3EA68086 0x3E918086 0x3E928086 0x3E988086 0x9B418086 0x9BCA8086 0x9BCC8086 0x9BC88086 0x9BC58086 0x9BC48086</string> Link to comment Share on other sites More sharing options...

Administrators Hervé Posted August 12, 2023 Administrators Share Posted August 12, 2023 Maybe you ned to inject your screen's EDID value. See our FAQ topic on the matter. Link to comment Share on other sites More sharing options...
KazuDante Posted August 13, 2023 Author Share Posted August 13, 2023 Question, is it normal when using igfxvesa or invalid I'd like 12345678 that the OS sees the display as being screen mirroring ? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted August 14, 2023 Administrators Share Posted August 14, 2023 'can't remember if screen mirroring is enabled by default in VESA mode but it really does not matter. It's not the proper way to run macOS, so... no point wasting any time on that. Link to comment Share on other sites More sharing options...
KazuDante Posted September 2, 2023 Author Share Posted September 2, 2023 another question , in your working HD620 on sonoma , does the laptop panel have a ACPI path , like _SB.PCI0.GFX0.XXXX ? Sadly i did not take a screenshot when i had win11 installed but during the process of pulling EDID info i saw it showed 3 options but 3rd was the only active( i assume its the internal display ) , so im guessing that maybe connector2 is my internal and not con0 or con1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted September 2, 2023 Administrators Share Posted September 2, 2023 Laptop's built-in screen is always connector con0. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted September 3, 2023 Moderators Share Posted September 3, 2023 Not according to your IOReg file But now I see you have this in your Config file. Disable it or delete it PciRoot(0x0)/Pci(0x1C,0x0)/Pci(0x0,0x0) Link to comment Share on other sites More sharing options...
