This EFI will suit any X1C4 regardless of CPU model<sup>1</sup>, amount of RAM, display resolution<sup>2</sup> and internal storage<sup>3</sup>.
<a name="CPU">1</a>. Optional custom CPU Power Management guide.
<a name="Res">2</a>. 1440p displays should change NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> UIScale:2 to get proper scaling while booting.
<a name="NVMe">3</a>. Follow NVMe fix guide below for NVMe drives.
This bootloader configuration will probably suit other 6th generation Thinkpads, but there could be some defacts (i. e. not working usb ports, can't connect any displays.. etc.). If you own a model other then a T460s check out these repositories:

How to update the bootloader
- Download the latest release
- Copy and Paste your
PlatfromInfo - Enable optional kexts if needed (NVMEFix, AirportItlwm, etc.)
- Test the new bootloader with an USB stick (Set
BootProtect: Nonewhenever booting with external drives) - Customize boot preferences (skip picker, disable verbose, etc.)
- Mount your ESP partition
- Backup your old EFI folder and replace it with the new one
Enable Intel WLAN cards
Two different drivers are under development for Intel WiFi support: `AirportItlwm.kext` and `AirPortOpenBSD.kext`. Do NOT use them both at the same time.
- Open
/EFI/OC/Config.plistwith any editor - Add the content of #intel-wlan - macOS 11.plist or #intel-wlan - macOS 12.plist according to your macOS version
- Save and reboot the system
Note: The drivers provided in this repo are for Big Sur and Monterey only; if you're running a different version of macOS please use the corresponding AirportItlwm.kext or AirPortOpenBSD.kext.
Optional: Remove unnecessary firmware files from OpenIntelWireless drivers.
Enable non-natively supported Broadcom WLAN cards
- Download AirportBrcmFixup and BrcmPatchRAM.
- Copy AirportBrcmFixup.kext, BrcmBluetoothInjector.kext, BrcmFirmwareData.kext and BrcmPatchRAM3.kext to
/EFI/OC/Kexts - Open
/EFI/OC/Config.plistwith any editor - Add the content of [#broadcom-wlan.plist](/EFI/OC/#broadcom-wlan.plist
- Save and reboot the system
Fix NVMe power management
- Open
/EFI/OC/Config.plistwith any editor - Add the content of #nvme-fix.plist
- Save and reboot the system
Custom CPU Power Management
- Run the following script in Terminal
git clone https://github.com/corpnewt/CPUFriendFriend; cd CPUFriendFriend; chmod +x ./CPUFriendFriend.command; ./CPUFriendFriend.command- When asked, select preferred values
- From the pop-up window, copy
ssdt_data.amlinto/EFI/OC/ACPI/folder (rename it if you'd like) - Open
/EFI/OC/Config.plistwith any editor - Add the content of #cpu-pm.plist (make sure SSDT-PLUG.aml is disabled and match your new SSDT filename)
- Save and reboot the system
ThinkPad Dock USB ports mapping
I've never had one so there's a chance something might not be working. USB mapping guide.
Enable HiDPI
- Disable SIP
- Run the following script in Terminal
bash -c "$(curl -fsSL https://raw.githubusercontent.com/xzhih/one-key-hidpi/master/hidpi.sh)" - Follow the instructions, then reboot
- Re-enable SIP (if desired)
Enable multimedia keys, fan & LEDs control
- Download and install YogaSMC-App-Release.dmg (both the pref-panel and app itself)
- Open the app
- Check the
launch on loginoption
Use PrtSc key as Screenshot shortcut
Super useful shortcut that I wish I had it on my previous MBP. Default is ⌘⇧5.
- Open SystemPreferences.app
- Go under
Keyboard > Shortcuts > Screenshots - Click on
Screenshot and recording optionsfield - Press
PrtScon your keyboard (it should came out asF13)
Add Apple Watch authentication to sudo
If you have an Apple Watch and you already replaced the build in WiFi card, you could enable authenticating as sudo with you Apple Watch using pam-watch
-
Download the latest ZIP file
-
Unzip, which by default creates a folder called pam-watchid-main.
-
Open Terminal and install it:
$ cd ~/Downloads/pam-watchid-mainsudo make install
-
Regsiter the new PAM module for sudo:
- Edit /etc/pam.d/sudo
- Add a new line under line 1 (which is a comment) containing:
auth sufficient pam_watchid.so
That’s it. Now, whenever you use sudo, you have the option of using your Watch to authenticate.

Monitor temperatures and power consumption
- Download and install HWMonitor
- Check
launch on login(optional)
Faster macOS dock animation
This enables auto-hide and speeds up the animation
-
Run the following script in Terminal
defaults write com.apple.dock autohide-delay -float 0; defaults write com.apple.dock autohide-time-modifier -float 0.5; killall Dock
