Kexts
Here I explain what each injected kext is used for.
| Kext | What is it used for | Is it required |
|---|---|---|
| AppleALC | Fixes audio | Yes |
| CPUFriend | Fixes CPU power management | Yes |
| CPUFriendDataProvider | Provides information about the CPU for CPUFriend | You need to make a custom CPUFriendDataProvider) if you have a different CPU |

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:
| 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 |
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:
| Feature | Setting |
|---|---|
| HiDPI | Enable HiDPI |
| Icon | MacBook Pro |
| Resolution | 1920×1080 |
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
