This EFI will suit any T460s regardless of CPU model¹, amount of RAM, display resolution² and internal storage³.

1. Optional custom CPU Power Management guide.
2. 1440p displays should change NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> UIScale:2 to get proper scaling while booting.
3. Follow NVMe fix guide below for NVMe drives.

This bootloader configuration may be compatible with other 6th generation ThinkPads with some caveats (i.e. not working USB ports, display ports, etc.). You may find more luck searching for your specific device on GitHub. Here are some notable repositories for similar devices:

1. Create an installation media
2. Download the latest EFI folder and copy it into the ESP partiton
3. Change your BIOS settings according to the table below
4. Boot from the USB installer (press F12 to choose boot volume) and start the installation process

1. Run the following script in Terminal

git clone https://github.com/corpnewt/GenSMBIOS && cd GenSMBIOS && chmod +x GenSMBIOS.command && ./GenSMBIOS.command

2. Type 3 to Generate SMBIOS, then press ENTER
3. Type MacbookPro16,3 5, then press ENTER. Leave this Terminal window open.
4. Open /EFI/OC/Config.plist with any editor and navigate to PlatformInfo -> Generic
5. Add the script's last result to MLB, SystemSerialNumber and SystemUUID

6. Save and reboot the system

1. Download the latest release
2. Copy and Paste your PlatfromInfo
3. Enable optional kexts if needed (NVMEFix, AirportItlwm, etc.)
4. Test the new bootloader with an USB stick (Set BootProtect: None whenever booting with external drives)
5. Customize boot preferences (skip picker, disable verbose, etc.)
6. Mount your ESP partition
7. Backup your old EFI folder and replace it with the new one

1. Open /EFI/OC/Config.plist with any editor
2. Add the content of #touchscreen.plist
3. Save and reboot the system

Note: Tested on macOS BigSur, working with gestures.

The EFI contains macOS Monterey and Ventura compatible drivers. The default driver enabled in config.plist is macOS Monterey compatible. Should you need the Ventura driver, please disable Airportitlwm.kext and enable Airportitlwm-13.kext. If you're running a different version of macOS please download and enable a compatible version of AirportItlwm.kext.

If you have bluetooth problem please reference to the IntelBluetoothFirmware

Optional: Remove unnecessary firmware files from OpenIntelWireless drivers.

1. Download AirportBrcmFixup and BrcmPatchRAM.
2. Copy AirportBrcmFixup.kext, BrcmBluetoothInjector.kext, BrcmFirmwareData.kext and BrcmPatchRAM3.kext to /EFI/OC/Kexts
3. Open /EFI/OC/Config.plist with any editor
4. Add the content of #broadcom-wlan.plist
5. Save and reboot the system

If you have bluetooth problem please reference to the AirportBrcmFixup

1. Open /EFI/OC/Config.plist with any editor
2. Add the content of #nvme-fix.plist
3. Save and reboot the system

1. Run the following script in Terminal

   git clone https://github.com/corpnewt/CPUFriendFriend; cd CPUFriendFriend; chmod +x ./CPUFriendFriend.command; ./CPUFriendFriend.command
   

2. When asked, select preferred values

3. From the pop-up window, copy ssdt_data.aml into /EFI/OC/ACPI/ folder (rename it if you'd like)

4. Open /EFI/OC/Config.plist with any editor

5. Add the content of #cpu-pm.plist (make sure SSDT-PLUG.aml is disabled and match your new SSDT filename)

If you have an Apple Watch and you already replaced the built-in WiFi card, you could enable authenticating as sudo with you Apple Watch using pam-watch.

1. Download the latest ZIP file

2. Unzip, which by default creates a folder called pam-watchid-main.

3. Open Terminal and install it:

   cd ~/Downloads/pam-watchid-main
   sudo make install
   

4. Register 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.

1. Download and install HWMonitor
2. Check launch on login (optional)
