malikabuzar Posted September 2, 2019 Author Share Posted September 2, 2019 Both methods were tried. -igfxvesa resulted in Kernel Panic. Adding ig-platform-id and fake id both 0x12345678 let me boot the OS and get to the desktop. Repaired permissions using "diskutil resetUserPermissions /'id -u' and rebuilt cache using "sudo kextcache -i /", then restarted with same result of Kernel Panic. Did I do this right?? How can we eliminate DVMT prealloc memory as possible culprit of unexpected results??? As I mentioned I used the estimation from another website to determine the DVMT prealloc of my machine. On 9/1/2019 at 4:57 AM, malikabuzar said: Graphics DVMT prealloc is 128 MB. (Determined with the help of a tutorial which says that if your Dedicated Graphics Memory in Windows is shown to be less than 128, your DVMT prealloc is Dedicated Memory + 32 and if it is 128 or greater then DVMT prealloc is equal to the Dedicated Memory. My Dedicated Graphics Memory is 128 MB, so...). Expand Is there any other, more accurate method to ensure the DVMT memory size?? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted September 2, 2019 Administrators Share Posted September 2, 2019 You boot your current config (which includes the Broadwell DVMT adjustment) with iGPU fake id and ig-platform-id set to 0x12345678 Once at the macOS desktop, you open up Terminal and repair permissions + rebuild your cache according to the instructions published in our FAQ section You then reboot without the iGPU faked-id or ig-platform-id set to 0x12345678 You can read about the DVMT settings and the associated requirement in Firewolf's original blog. Of course, if your BIOS permits it, set DVMT accordingly (between 64MB and 128MB). https://www.firewolf.science/2015/04/guide-intel-hd-graphics-5500-on-os-x-yosemite-10-10-3/ Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted September 2, 2019 Moderators Share Posted September 2, 2019 Remove folder /EFI/Clover/kexts/10.14 Looking at your IOReg file, it doesn't show Lilu nor Whatevergreen loaded. So Clover must be loading files from from 10.14 which is missing Lilu.kext that's needed with Whatevergreen. NVM, you're installing HS which is 10.13, but good idea to remove that folder anyway. With that said, you must be booting from different source than the Clover folder you have attached. Confirm there is no EFI folder on the root? Not having any previous info about the source of the installer, check if the following kexts exist in /S/L/E AppleIntelBDWGraphicsFramebuffer AppleIntelBDWGraphics AppleIntelHD5000Graphics AppleIntelHD5000GraphicsGLDriver.bundle AppleIntelHD5000GraphicsMTLDriver.bundle AppleIntelHD5000GraphicsVADriver.bundle Link to comment Share on other sites More sharing options...

"Graphics Driver failed to Load: could not register with frame buffer driver." Attached is my compressed efi folder from EFI partition. Please have a look at it. You might identify some new source of problem. EFI.zipFetching info... Link to comment Share on other sites More sharing options...
