Hi, First sorry for the long post, I spent around 120+ hours fighting to install osx using opencore... I just got a new laptop and was able to install Catalina and Big Sur. I need Osx for work and my 2011 Macbook Air is obsolete. I got the intel iGPU to work but only in remote control using RealVNC. I can't connect to any display, No displays are found and no connections work (HDMI, DP) [ Thunderbolt I can't test]. I would appreciate a look at my DSDT and any patch it needs. Thanks. {running iGPU acceleration without _OFF for dGPU keeps the laptop screen displaying the boot verbose and the remote control the desktop and the mac dont offer the option to display on the real screen} {running iGPU acceleration with DSDST patch for dGPU _OFF or Hybrid have my laptop screen go black and not show up as a screen when I connect through remote} System info: Cpu: Intel Core i7-10875H SG Mode available: Only Muxless (but confirmed it boots screen on iGPU first before its taken over by dGPU when it displays the UIEFI alienware logo] IGPU: seems to be intel HD 630 headless. [was able to display its starting american megatrend boot logo before uiefi and geforcce take over and reset the bios values for primary screen and auto options] DGPU: nVIDIA GeForce RTX 2070 Super (Dell) [I couldn't disable it in bios using ru.efi (couldn't patch and flash my bios, too new or couldn't find the right tool to reflash it as a rom) Mac SSD: Samsung SSD 970 EVO Plus 500GB (500 GB, PCI-E 3.0 x4) Windows SSD: PC611 NVMe SK hynix 1TB (1024 GB, PCI-E 3.0 x4) [slot Disabled with DSDT ot it doesnt boot into mac] What I think might work: removing the dGPU from the DSDT completely or finding how to take over the screen after _OFF and give it back to iGPU ( saw a switch function in DSDT that act different depending on a value) or removing dGPU and reconnecting lcd to iGPU or alas ... Crying for choosing a FHD 144hz Gsync display instead of a 4K 60hz, maybe they have muxed... What does and doesnt work for now: Wifi works but slow and not full speed Lan doesnt work Brightness keys doesnt work Sleep under no iGPU acceleration freezes picture and screen doesnt sleep Touchpad and keyboard works Sound works but not the microphone and sound only comes out from the right speaker Camera works Bluetooth works (v3) but BTver5 doesn't and airdrop doesnt work Thunderbolt (didnt take time to test it as I dont have any cable or hardware for it, my guess is it doesnt, for now its disabled in the bios) Cheers BiosHackOptions.rar Screens EDIDS.rar Send me JAKAMYs-FullAccelRemoteOnly.rar WindowsDSDT.amlAIDA64Report.rar

Hello, Good day everyone, As visible from the topic i have and alienware 15r4 laptop which is a gsync panel and has 1070 gtx directly plugged into the display and then the UHD630 which is connected to the usb-c for video for god know what reason. Now i had a very stable build of high sierra till now but yesterday i broke it and the installation is now kaput! I really need help with the right clover for doing the installation, i have tried my own EFI's for the installation but it doesn't work at all. I have all my POST EFI's in here: https://github.com/rajverma1985/Alienware-15R4-High-Sierra No matter what i do i can't get past the error which says "service exited due to signal bus error" and i have also tried to inject intel, tried nvda_drv=1, nv_disable =1(separately) along with -disablegfxfrimware and then injecting nvidia web but nothing works. Any help on this would be really appreciated. My present config plist inside the USB looks like the one attached. config.7z
