Overview
Summary
This X1C7 Hackintosh project aims to be an all-in-one maintained hub for Opencore-based hackintoshes on the Thinkad X1 Carbon Gen 7. In short, this x1c7-hackintosh is very stable and is currently our daily driver (Simon and Aidan). We fully recommend this project to anyone looking for a MacBook alternative. There are also multiple contributors to this project who have all helped in various fashions - see credits.
This repo is meant to serve as a hub and guide for users of the X1C7 and X1Cx community in general. <br />
Functional Overview
What works, what doesn't and why.
<details> <summary><strong> WHAT IS WORKING </strong></summary>Install
| working | Device / Step | Comment |
|---|---|---|
| ✅ | Booting macOS installer | |
| ✅ | Installed to HD | |
| ✅ | Installed to HD and Dualbooting Windows on the same drive Windows | Use this guide to setup dualboot on the same drive |
Post-Install
| working | Device / Step | Comment |
|---|---|---|
| ✅ | Graphics | Requires WhateverGreen.kext |
| ✅ | Touchpad | Requires VoodooGPIO, VoodooI2CServices,VoodooInput This was very trial-and-error based and I reccomend looking at our config.plist. Order and location matter. |
| ✅ | Trackpoint | Requires VoodooPS2 |
| ✅ | Keyboard | Requires VoodooPS2 |
| ✅ | Keyboard-Multimedia Fn keys | Requires YogaSMC.kext + TODO: Add ACPI here and YogaSMC-App |
| ✅ | WiFi | Native WiFi with AirportItlwm.kext - no companion app required |
| ✅ | Bluetooth | IntelBluetoothFirmware.kext and IntelBluetoothInjector.kext <br> ⚠️ audio input (e.g. of headset) is not working, see #3 |
| ❌ | WWAN | DISABLED at BIOS to conserve power |
| ✅ | Ethernet | IntelMausi.kext for bundled USB-C adapter |
| ✅ | Hibernation | hibernatemode=3 |
| ✅ | HDMI output | Requires WEG? |
| ✅ | USB A / USB C | |
| ✅ | Thunderbolt 3 | Tested with a Vega 64 EGUP in a Razer Core X Enclosure, requires TB3 BIOS Assist to be ENABLED |
| ✅ | Webcam | checked on 2021-02-19 |
| ✅ | Audio | ✅ Internal Speaker and Headphones / Line in <br> ⚠️ Internal Microphone not working <br> Realtek ALC285, layout 11, 21, 31 (all seem to work equal) TODO supported layouts have changed ➡️ boot-args: alcid=71 |
| ✅ | iCloud (App Store, iMessage, FaceTime, etc) | All iServices work |
| ❓ | HiDPI, Handoff, Sidecar | Handoff/sidecar sporadic function. Would not rely on these |
| ❌ | Fingerprint Reader | Disabled in BIOS to save power |
| ✅ | Power Management Optimizations | Fully working with CPUFriend and CPUFriendFriend, more options with YogaSMC to come |
| ✅ | Intel SpeedStep | Fully working (Higher performance when plugged in, lower when on battery, tested with GeekBench 5) |
</details> <details> <summary><strong> LIMITATIONS </strong></summary>✅ Fully functional; ❓ Untested/Intermittent (might work); ❌ Non-functional
Limitations what is not working as expected or improvements:
</details> <details> <summary><strong> Common Issues </strong></summary>gioLockscreenState error is a common one working with uncommon iGPUs (like our UHD 620) See issue #11 for solution
</details> <br />Hardware Compatability
Lenovo allows for many different hardware configurations and will update CPU generations while maintaining the same generation. This makes is somewhat confusing to tell exactly what hardware you have and exactly what this project was meant for. The Shared Hardware tab lists all common hardware info between different models of the X1C7. Following tabs for specific model numbers provide small modificaitons needed to the EFI for their respective model numbers, if needed.
Odds are your hardware will work with minor modifications to the EFI
