EMU7989 Posted January 13, 2023 Author Share Posted January 13, 2023 I can access the desktop in VESA mode, but the screen will still be black after closing. This is my startup video. Can OCLP solve this problem when using MBP13,1 and SKL graphics settings? Is it useful to inject EDID into the built-in display? Video.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 13, 2023 Administrators Share Posted January 13, 2023 Do try to inject your screen's EDID though if it's not required for Monterey, it should not be for for Ventura. Feel free to experiment with OCLP if the usual tricks don't work for you. Link to comment Share on other sites More sharing options...
EMU7989 Posted January 13, 2023 Author Share Posted January 13, 2023 I tried to use OCLP, but the system failed to start after applying the patch (using MBP14,1, SKL graphics settings) Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 13, 2023 Administrators Share Posted January 13, 2023 You have to be more specific with regards to your statement about "using MBP14,1, SKL graphics settings". OCLP is to patch unsupported systems. As such, if you want to apply the tool to your system, you have to apply it with MBP13,1 SMBIOS selected in the tool (not MBP14,1 which is a supported platform), then boot with MBP13,1 SMBIOS + -no_compat_check boot arg.

EMU7989 Posted January 15, 2023 Author Share Posted January 15, 2023 Thank you very much for your suggestion, but I will not be able to access the system after doing so, and restart directly Link to comment Share on other sites More sharing options...
EMU7989 Posted January 17, 2023 Author Share Posted January 17, 2023 I found that HDMI can be used to connect to the external display. The graphics card information is correctly displayed as "HD 520 2048MB", and the brightness of the built-in display can be adjusted. The built-in display will light up, but there is no display I compared the IOReg files under monterey and ventura, and found that the system under ventura failed to recognize "Apple Display". Is this the reason for the black screen (I used an external display, KBL graphics settings) Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 17, 2023 Administrators Share Posted January 17, 2023 For your info, on a laptop Hackintosh: internal built-in screen usually is -if not always- attached to FB@0 (i.e. con0) and should always register as AppleBacklightDisplay. external screens usually are attached to FB@1/@2/@3 (i.e. con1/con2/con3) and should always register as AppleDisplay.

EMU7989 Posted January 18, 2023 Author Share Posted January 18, 2023 So the built-in screen doesn't work because of the FB port? How can I fix it? My built-in screen displays as "Unknown Display". Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 18, 2023 Administrators Share Posted January 18, 2023 Did you try and inject your screen' EDID as suggested previously? Link to comment Share on other sites More sharing options...
