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
