Opencore-based Hackintosh EFI and guide for Lenovo Thinkpad X1 Carbon Gen 7

macOS on Thinkpad X1 Carbon 7th Generation

OpenCore-based Hackintosh EFI and guide for Lenovo Thinkpad X1 Carbon Gen 7. This guide has been generated for both the model numbers specified below.

Usage

This OpenCore config comes with empty PlatformInfo / SMBIOS!

Follow Dortania's OpenCore Install Guide to generate your own: Laptop Coffee Lake and Whiskey Lake > Platforminfo. If you own a Lenovo 20R1 (Intel 10th gen) also note the hint at Hardware Compatability

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.

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
⚠️ 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
⚠️ Internal Microphone not working
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)

Fully functional; Untested/Intermittent (might work); Non-functional

LIMITATIONS

Limitations what is not working as expected or improvements:

Common Issues

gioLockscreenState error is a common one working with uncommon iGPUs (like our UHD 620) See issue #11 for solution


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

    Doesn't boot with Intel iGPU spoof enabled

    Hi,

    I'm trying to launch Catalina installer on 20QE-SP40U (that is almost the same as 20QE-S01L00), but with default config it doesn't boot (it stucks after "IOConsoleUsers: gIOScreenLock..."). I already followed the guide without any success.

    If I disable the Intel iGPU spoof it boots, with in VESA mode

    Any clue?

    [Kext] ECEnabler - Instant battery status - no more ACPI patches?

    ECEnabler is a Lilu plugin which allows macOS to read any size of EC field, meaning that no more ACPI patches are needed to split EC fields up within ACPI.

    Question About X1 Carbon 7th 20QD001VUS

    Hello!

    I was wondering if it is possible to boot a 20QD001VUS with this EFI ? I've tried MacOS from 12 all the way to 10 with this EFI and I get stuck at the Apple logo. Would be awesome if there is a way to get this to work on my laptop.

    Please let me know!

    Using efi in this repo with platformInfo added, BIOS configuration referred to tylernguyen/x1c6-hackintosh, however, I got stuck when installing big sur with 13 minutes remaining. Does this might be caused by my wrong configuration or incompatible os version? Thanks a lot.

    I had a 20R1 model and my laptop stuck at booting process. I googled the error code [EB]#LOG:EXITBS:START], and it seems to related to CFG Lock. I could not find the option to disable CFG lock in bios, and neither AppleCpuPmCfgLock nor AppleXcpmCfgLock in config.plist works for this issue.
