# Overview:

> :warning: The repository has finally been updated to the latest version of OpenCore. I've been testing this configuration on the latest version of macOS Monterey and everything works as expected. Trackpoint and upper touchpad buttons are fixed now as well! Oh and battery patching is no longer buggy, thanks to ECEnabler kext. I've also tested the dock station, which seems to work fine with some USB patching. Additionally, new RealtekCardReader kext fixes all problems with the card reader.

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.

# Installation
To use this EFI, follow [Dortania's OpenCore guide](https://dortania.github.io/OpenCore-Install-Guide/). You will need to create a bootable USB with macOS image on it, then copy the entire EFI folder on it. Remember to first set BIOS settings, use kexts that match your hardware configuration, make changes to the config.plist according to your laptop's specification and **make sure you have backups**.

# Tweaks:

If you use the builtin Intel Wi-Fi, inject [Itlwm](https://github.com/OpenIntelWireless/itlwm) and [IntelBluetoothFirmware](https://github.com/OpenIntelWireless/IntelBluetoothFirmware) kexts.

### CPU Power Management
CPU power management is done by `CPUFriend.kext` while `CPUFriendDataProvider.kext` defines how it should be done. `CPUFriendDataProvider.kext` is generated for a specific CPU and power setting. The one supplied in this repository was made for the i7-7600U. You might have a different CPU, and if you do - you need to make `CPUFriendDataProvider.kext` yourself using [CPUFriendFriend](https://github.com/corpnewt/CPUFriendFriend) tool. Read [this guide](https://dortania.github.io/OpenCore-Post-Install/universal/pm.html#using-cpu-friend) for more information.

The settings I used for CPUFriendFriend, for managing CPU power:
| Feature | Setting |
| ------------- | ------------- |
| LFM (Low Frequency Mode) | 800Mhz (recommended value from Intel ARK website) |
| EPP (Energy Performance Preference) | 0x3F (focused on performance, but with decent battery saving)|
| Performance Bias | 0x05 (focused on fair performance and high stability)|
| Additional Energy Savings Options | Yes |

### Fixing iServices
One of the most important things that many people don't know how to properly set up is iServices.
Actually, it's pretty easy if you do it **before** the installation.
Just follow the [original guide](https://dortania.github.io/OpenCore-Post-Install/universal/iservices.html) but generate the serial and inject it **before** you start installing macOS. This will save you a lot of time and will make iServices work right after the installation.

### Secure Boot and ApECID
If you're using [Itlwm](https://github.com/OpenIntelWireless/itlwm), you need to set SecureBootModel to Default. If you don't use that kext, you can have it set to the closest one that matches your SMBIOS for higher security. I used `j680` from **MacBookPro15,1** SMBIOS.

You can also [generate your own ApECID](https://dortania.github.io/OpenCore-Post-Install/universal/security/applesecureboot.html#apecid) (stands for Apple Enclave Identifier) which is known as the "highest level of security". Used along with a custom SecureBootModel will make your device even more secure.

### FileVault
I won't cover this topic in the README, because I don't use FileVault, but it is possible to have it working on this laptop and most other machines. If you want to use it - follow the [guide](https://dortania.github.io/OpenCore-Post-Install/universal/security/filevault.html).

### Configure sleep
![Screenshot](https://raw.githubusercontent.com/XXCoreRangerX/Hackintosh-HP-EliteBook-840-G4/master/img/sleep.png)

These are the settings that work for me. Hibernation isn't supported on Hackintosh, therefore should be disabled.

To apply patches for sleep - type the following commands in the terminal:
```
sudo pmset hibernatemode 0
sudo rm -f /var/vm/sleepimage
sudo mkdir /var/vm/sleepimage
sudo pmset autopoweroff 0
sudo pmset -a standby 0
sudo pmset autorestart 0
sudo pmset proximitywake 0
sudo pmset disksleep 0
sudo pmset tcpkeepalive 0 (optional)
```
Make sure to disable wake on LAN in power settings. I also recommend to disable Power Nap, which causes random wake up calls on my laptop.

### HiDPI Scaling (Retina Scaling)
![Screenshot](https://raw.githubusercontent.com/XXCoreRangerX/Hackintosh-HP-EliteBook-840-G4/master/img/hidpi.png)

Retina displays on real Apple devices have a high pixel density because of HiDPI scaling. 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](https://github.com/xzhih/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:
| Feature | Setting |
| ------------- | ------------- |
| HiDPI | Enable HiDPI |
| Icon | MacBook Pro |
| Resolution | 1920x1080 |

**Note:** HiDPI only works on Full HD or higher

### Wi-Fi button fix
I found a way to fix the Wi-Fi button, that was previously not doing anything. Turns out it's a regular key, that is blocked in default `VoodooPS2Keyboard` configuration. I mapped it to F16, because it was the safest key with no general use under macOS (you can assign it to any other key in `VoodooPS2Keyboard’s` `info.plist` file, if needed).

I'll provide the instructions needed for the fix.

First, you'll need to determine what is your Wi-Fi device's name. To do so, type in ```networksetup -listnetworkserviceorder | sed -n '/Wi-Fi/s|.*Device: \(.*\)).*|\1|p'``` in the terminal. Generally it's named ```en3```. Remember the interface's name, as you will need it in further steps.

1. Open Automator app and create a new Service
2. Set "Service receives selected: to "no input" in "any application"
3. Add an action named "Run Shell Script". It's in the Utilities section of the Actions Library
4. Insert ```networksetup -getairportpower en1 | grep "On" && networksetup -setairportpower en1 off || networksetup -setairportpower en1 on``` into the text box and test run it using the Run button (top right)
5. Save it and give it a name you will remember
6. Go to System Preferences -> Keyboard -> Shortcuts
7. Go to the Services section, and scroll down to General - you should find your service there. Once you select it - click "add shortcut" and press the Wi-Fi button.

Done! Now you can use the Wi-Fi button to enable and disable Wi-Fi. However, the LED will require additional fixes - making a custom SSDT would probably make it work.

**Note:** If you have multiple user accounts on your laptop - you will have to repeat all of these steps for each account.

## 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)
- Boot chime
- External display on VGA
- Dot to disable touchpad (in the upper left corner of the touchpad, might be possible with VoodooPS2)
- Wi-Fi LED (always orange, but if there's an LTE module connected it's always white)
- LTE module (being detected as Ethernet and not working)
- Booting Linux from OpenCore

## Not tested:
- NFC module
