Hackintosh-HP-EliteBook-840-G4

OpenCore EFI for the HP EliteBook 840 G4

Overview:

This repository was built to make a fully working OpenCore EFI for this laptop. It’s based on my work and help from other people. 

Laptop Specification:

• BIOS: For the highest stability use 1.29 (latest version works too, but need to remake SSDT-BATT for better battery management)
• CPU: Intel® Core i7-7600U (for other CPUs, you need to make CPUFriendDataProvider.kext yourself)
• GPU: Intel® HD Graphics 620
• RAM: 8GB DDR4 2133MHz
• Wi-Fi/BT: Apple AirPort BCM94360CS2 (if you’re using the builtin Intel WiFi – inject Itlwm and IntelBluetoothFirmware kexts)
• Audio: Conexant CX8200
• ETH: Intel® Ethernet Connection I219-LM (I219-V also supported with IntelMausi)
• Display: 14″ Full HD Touchscreen (for the non-touch model, remove everything regarding VoodooI2C, and use VoodooInput from VoodooRMI)
• Touchpad: Synaptics SMBus
• Keyboard: PS2 HP Keyboard
• Webcam: HP HD Camera (the camera may work out of the box, or not work at all – there is no way to fix it)
• SD Card Reader: Realtek

Tweaks:

ACPI

Here I explain what each SSDT in the EFI does.

ACPI renames and patches

Here I explain what does each ACPI patch do.

Kexts

Here I explain what each injected kext is used for.

If you use the builtin Intel Wi-Fi, inject Itlwm and IntelBluetoothFirmware kexts.

CPU Power Management

The settings I used for CPUFriendFriend, for managing CPU power:

Configure sleep

These are the settings that work for me. Setting hibernatemode to 0 doesn’t let me put the laptop into sleep mode, so I kept the default value.

To apply patches for sleep – type the following commands in the terminal:

sudo pmset autopoweroff 1
sudo pmset powernap 0
sudo pmset proximitywake 0
sudo pmset sleep 1
sudo pmset standby 1

HiDPI Scaling (Retina Scaling)

Retina displays on real Apple devices have a high pixel density because of HiDPI scalling. One logical pixel is four physical pixels on Retina displays. This can be emulated on Hackintoshes too. I used a script called one-key-hidpi which works pretty good on this device. Since Full HD is quite hard to work on while using a 14″ display, this is a really useful fix. However, using it will make the Apple boot logo large at 2nd boot stage, and I haven’t found a way to fix that yet.

These are the options I used in the script:

Note: HiDPI only works on Full HD or higher

Not working:

• DRM (isn’t supported on iGPU only systems)
• Proper CFG Unlock (there isn’t an option in the BIOS, and I didn’t find any way to disable it)
• FingerPrint Scanner (currently there’s no way to emulate an OEM fingerprint scanner under macOS)
• Trackpoint (works with VoodooPS2Mouse, but using that kext breaks the touchpad – still working on it)
• Boot chime
• External display on VGA
• Dot to disable touchpad (in the upper left corner of the touchpad, might be possible with VoodooPS2)
• WiFi Button (LED always orange, button does nothing, might be possible with a custom SSDT)
• F3 and F10 functions (need to disable FN+F3 and map FN+F10 to Play/Pause)

Not tested:

• NFC module
• LTE module
• SC reader
• Dock station
• USB-C
• HP Sure View
