    I really don't understand how to patch the buses. Not really familiar with Dortania's patching guide :(

    What exactly do you mean by patching the "connectors bus ID"?

    I actually gave up. No matter what I have tried, this thing refuses to work. Blackscreen. :(

    I gave up on hackintoshing my main laptop. It's really frustrating. No screen output whatever I tried. I'll try to get a output on a external monitor with HDMI. Maybe it'll help to get the internal display working..

    @Mrgeque I did try these settings, but none of them have solved my issue. I guess something is wrong with the framebuffers, but I'm not sure.

    It's a Medion Erazer P6689. I'm sorry to say that, but there's nothing available on the internet regarding hackintosh on this laptop. I never tried to remove fb and stolenmem. I think that I need connector patches, but I don't know where to start.

    Hi. I'm new here, and I apologize for something I have done wrong. I have got a very annoying issue on my Medion laptop (yeah, Medion, probably not a known brand, but anyway.. :D). I have successfully installed Big Sur 11.2.3 on it using OC 0.6.8, actually, everything is working except the...
