A collection of all files needed to run Ventura on a Dell Precision 5550.
This is more of a compilation of information and configs from various repositories and forums than a place where real development happens. This repository should contain everything needed to get Ventura up and running on your Dell Precision 5550 laptop.

The stock Intel Wi-Fi cards are still unstable in macOS. So to use Wi-Fi with "AirPort feeling", you will have to replace it for a supported card. However this is harder said then done. The installed Intel card is soldered to the motherboard. It is possible to buy a connector and use the second ssd slot to instal the other card. However afterwards the new card and the existing antenas have to be fitted with new prolonged cables, which are hard to get by. The other possibility is to try to use the following kext itlwm. Its an interesting and promissing project, which tries reverse engineer the drivers for the card.
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 Intel Core i7-10875H and is optimized for optimized performance.
The following kexts are present:
- Airportitlwm.kext: Intel wifi, sometimes works, mostly not.
- AppleALC.kext: Support for audio.
- AppleRTL815XEthernet110.kext: Support for ethernet.
- BlueToolFixup: Bluetooth for macos.
- BrigtnessKeys: Allow using FN keys to adjust brightness, is not bound to the default keys.
- CPUFriend: Change the performance model of the CPU.
- CPUFriendDataProvider: Specification of the performance model.
- IntelBluetoothFirmware: Bluetooth for intel cards.
- Lilu: required - dependency to lot of other kexts.
- NoTouchID: no touchid popups will appear - nothing appeared during testing.
- NVMeFix: ssd support - non apple NVMe.
- SMCBatteryManager: monitoring, especially battery.
- SMCDellSensors: monitoring, especially fans on dell.
- SMCLightSensor: monitoring, especially ambient light sensor.
- SMCProcessor: monitoring, especially cpu temperature.
- SMCSuperIO: monitoring, especially fans.
- USBInjectAll: USB.
- UsbPorts: mapping of the ports on the machine.
- VirtualSMC: required - emulates SMC chip on macs
- VoodooI2C: required - keyboard, mice, trackpad
- VoodooI2CHID: required - keyboard, mice, trackpad
- VoodooPS2Controller: required - keyboard, mice, trackpad
- WhatteverGreen: required - enables graphics
While I have chosen these texts, I want to clarify that I'm not claiming it to be the optimal choice. I acknowledge that there are areas that could be enhanced.
Because of the sleep issues and the lack of a proper Wi-Fi card, I decided to use this project solely for experimenting with macOS, specifically Hackintoshing. It was a fantastic experience, and I gained a lot of knowledge about low-level stuff, particularly the interaction between actual computer components and the operating system. If you enjoy tinkering with fascinating things, I can highly recommend this hobby project. Feel free to add improvements via PR and report issues 🙂.
Happy hacking!
