SUMMARY:

Fully functional	Non-functional	Semi-functional. Additional pulls needed and welcomed.
Wifi and Bluetooth *need card replacement ⚠️	Fingerprint Reader (not needed, DISABLED at BIOS) ❌	HDMI, currently only outputs at 1080p.Though capable of 4K 4096x2150. ⚠️
USB A, USB C, Webcam, Audio Playback/Recording Sleep, Ethernet, Intel Graphics, TrackPoint and Trackpad ✅	Wireless WAN (DISABLED at BIOS) *ENABLED if you have a 2nd drive connected❌	Function keys, F1-F6 work. The rest need to be mapped and patched via DSDT/SSDTs. ⚠️
iCloud suite: App Store, iMessage, FaceTime, iCloud Drive, etc... ✅	Hibernation ❌	Power management, currently 5-6 hours with average usage. Maybe a custom injection with CPUFriend will optimize this? ⚠️
HiDPI, Handoff, Sidecar ✅		USB power property injection - unsure of real values. ⚠️
MicroSD card reader ✅		Thunderbolt 3 hotplug: proper patch needed. ⚠️

NEEDED:

A macOS machine would be VERY useful: to create install drives, and for when your ThinkPad cannot boot. Though it is not completely necessary.
Clover Configurator, if Clover is your bootloader.
Flash drive, 16GB or more.
Xcode works fine, but I prefer PlistEdit Pro.
MaciASL, for patching ACPI tables.
IOJones, for diagnosis.
Hackintool, for diagnosis.

WHERE TO START:

Explore links included this README, especially those in references and other x1c6-hackintosh repos.

Once you are ready, follow the series of README files included docs/.
1_README-HARDWAREandBIOS: Requirements before starting.
2_README-installMEDIA: Creating the macOS install drive.
3_README-POSTinstallation: Settings and tweaks post installation.
4_README-ACPIpatching: The hardest and most time consuming part, patching the system ACPI table for battery status, brightness, sleep, thunderbolt, thunderbolt hotplugging, etc...

• While you can plug-and-play most of my hotpatches if you have an x1c6, I still suggest that you dump and disassemble your own DSDT. This is imprortant as your DSDT maybe different from mine. And furthermore, you get to learn more about what's actually going on.

Create a pull request if you like to be added, final decision at my discreation.

OPTIMIZATIONS:

• Repaste the machine with thermal Grizzly Kryonaut.
• Undervolt the machine with Volta.
• If you must dual boot with Windows or Linux, I advise against paritition. What I recommend, instead, is getting a second compatible hard drive that fits in the WWAN card slot (I have the WDC PC SN520 NVMe 2242), install Windows/Linux onto that drive. Finally, boot into it with Clover or OpenCore.
• If your laptop did not come with WWAN, you can purchase additional antennas to add to your laptop. This is useful when using Wifi/Bluetooth cards that have 3 antennas.
