Opencore hackintosh of a Dell 7573 2-in-1 notebook

Dell Specs:

  • Dell 7573 with BIOS v1.16.0
  • i7-8550U
  • UHD 620
  • 16GB RAM
  • 512GB Skynix M.2 SATA SSD
  • 1080p touchscreen
  • RealTek integrated webcam

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.

What's working

  • Wifi and Bluetooth (replaced with Dell 1520 card)
  • Trackpad
  • Backlight
  • Audio - Built in and HDMI
  • All USB ports including USB-C
  • Power management including sleep
  • Touchscreen
  • SD Card Reader
  • HDMI Port
  • Fn keys to control volume and keyboard backlight
  • Combo jack
  • iMessage and FaceTime (plist in repo sanitized. You'll need to find your own SN)

What's not working

  • Integrated RealTek webcam
  • Fn keys to control display backlight

BIOS Configuration

Turn off the Secure Boot. That should be all.

UEFI Variables

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

Notes

  • 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!).
