    [GUIDE] General Framebuffer Patching Guide (HDMI Black Screen Problem)

    As already said, my Catalina setup is with OC 068, while the Ventura one uses OC 086. Could it be that the latter OC is misinterpreting this Kext ? Regards, G.

    @UtterDisbelief, @Feartech, @Edhawk and many other into several threads : Thanks a lot for your help and advises, since now my Ventura install works quite fine.

    Thanks, but it does not work much better. Going up to "startup" plus "prohibited sign" after Apple logo plus a little bit of progress bar. But the boot log is showing a lot of AppleIntelCFLGraphicsFramebuffer messages which I can't interpret. See attached file. What's up then ? Many thanks...

    Yes, I OCvalidate'd this config.plist, and the latter one seems clean, but still nothing showing on my screen after "OCSMC: SmcReadValue Key 4D534163 Size 2". I need help, please, because I believe I tried everything to clear this issue. Reminder : Opencore 0.8.6 used to install Ventura on...

    What means "headless mode" ?

    Hi, Thanks for your reply. I'm still struggling with display issues, I think. BTW : what mean these lines in the opencore txt file while I attempt to boot from an 'Install macOS Ventura' stick ? 485 23:394 00:008 AAPL: #[EB|BRD:NV] Mac-AF89B6D9451A490B 486 23:402 00:008 OCOS: OS...
