adamantinum Posted February 10, 2020 Share Posted February 10, 2020 Hi, I'm trying to configure OpenCore bootloader for my laptop. In the EFI atteached I have used a SSDT-EC prebuilt, so I don't know if it is right. Starting in verbose mode everything goes on, but after what I show in the image below appears, a black screen appears, so I think is an iGPU issue. I tried to connect a VGA display and while the main screen is black, that one show the apple logo and the progress bar full for 1/5 more or less. I have no idea about what to do, maybe patch the framebuffer? And in case, how? Thank you all in advance.

adamantinum Posted February 10, 2020 Author Share Posted February 10, 2020 Thank you, now the screen with the Apple and the bar (full at the same point) appear also on the laptop screen, but it stucks there. Here the screen, maybe should I remove the kext? 1 Link to comment https://www.insanelymac.com/forum/topic/342536-opencore-graphic-not-starting/#findComment-2707813 Share on other sites More sharing options...

Finally, I solved adding VoodooTSCSync.kext, it was an issue with my Asus bios. I tell you if you still have the same issue. 1 Link to comment https://www.insanelymac.com/forum/topic/342536-opencore-graphic-not-starting/#findComment-2708403 Share on other sites More sharing options...
