andresime Posted May 24, 2017 Share Posted May 24, 2017 Hi, i recently purchased a dell e5450 broadwell with this specs: i7-5600u 8gb ddr3 ram 128gb ssd intel hd 5500 + Nvidia gtx 840m display 1920x1080 I was able to install mac os sierra 10.12.5 with your fenomenal guide, and everything works exept the hd5500 full acceleration. i've tried so many times and spend many hours find a way to set my dvmt allocation to 64 (96mb effective) but with no luck cause i can't extract my bios.exe a14, it gaves me an error with every program i've tested. So i've gone all the way with framebuffer patch and id for the gpu intel injected. i've tried every combination with find and replace (for obvious reasons the ones for yosemite and el capitan would not work) and even the ones for sierra change nothing and the boot stops at gpu 0x43 kernel panic. I wonder if anyone with similar specs have come with a solution, thanks in advance, and keep in mind that i'm italian so close an eye with my english Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted May 25, 2017 Moderators Share Posted May 25, 2017 Use this from Windows or WinPE. See prerequisite here for guide to set DVMT or you could try adding these 2 kexts. IntelGraphicsDVMTFixup.kext Lilu.kext Your SMBios is incorrect, MBP11,2 is for Haswell, change it to MBP12.1 with Clover Configuration. Use the latest version 4.42.1 Link to comment Share on other sites More sharing options...
andresime Posted May 26, 2017 Author Share Posted May 26, 2017 Hi thank you very much! I was able to install the lilu kext but i'm not able to figure out how to install the intelgraphicsdvmtfixup alongside lilu cause from what i understand they work together. I made some progress and i was able to extract the bios rom and pe32 image of dxeipl, but when i use universal ifr extractor it gaves me "unknown protocol detected" I post the bios rom and the pe32 image extracted, there should be a way to convert this hex file in readable text so i can find the variable that i have to change with 0x3 for 96mb BIOS & PE32 .zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 26, 2017 Moderators Share Posted May 26, 2017 You probably extracted the wrong value. The offset to set DVMT are the same as my E7450 0x15b and 0x15c A14 IFR.txt.zip Link to comment Share on other sites More sharing options...
