I've hackintoshed the Dell 7XXX series for years now. This is my 3 generation HacBookPro. I like these machines because I feel they are easy to hack, you can find refurbs relatively cheap(-$700 USD), and the card reader actualy works.
This build is for Catalina 10.15.4 using Opencore 0.5.8.

Turn off the Secure Boot. That should be all.
In order to run macOS without having to use WhatEverGreen's framebuffer patching and CFG-related booter quirks, it is strongly recommended to modify a few UEFI variables. To do that, you can use the included ModifiedGrub.efi (credits brainsucker), which provides the setup_var command.
The following variables should be updated:
| Variable | Offset | Default value | Desired value | Comment |
|---|---|---|---|---|
| CFG Lock | 0x4C7 | 0x01 (enabled) | 0x00 (disabled) | Disable CFG Lock to prevent MSR 0x02 errors on boot |
| DVMT Pre-allocated | 0x76D | 0x01 (32M) | 0x02 (64M) | Increase DVMT pre-allocated size to 64M |
| DVMT Total GFX Memory | 0x76E | 0x02 (256M) | 0x03 (MAX) | Increase total GFX memory limit to maximum |
DISCLAIMER: those offset values are taken from 1.15.0 and 1.16.0 firmwares. DO NOT use them with older versions unless you have checked that they are the same.
Usage:
setup_var <offset> <value>
ex.
setup_var 0x4C7 0x00
- The included CpuFriendDataProvider is made for i7-8550U. If you have the i5-8250U processor, DO NOT use this kext. You can make a new data provider kext for that CPU (and make a PR!).
