Hardware compatibility 🧰

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:

  3. Save and reboot the system

Note: Tested on macOS BigSur, working with gestures.

Enable Intel WLAN cards

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.

Enable non-natively supported Broadcom WLAN cards
  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

Fix NVMe power management
  1. Open /EFI/OC/Config.plist with any editor
  2. Add the content of #nvme-fix.plist
  3. Save and reboot the system
Custom CPU Power Management
  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)

  6. Save and reboot the system

ThinkPad Dock USB ports mapping

Please follow this USB mapping guide.

Other tweaks

Enable HiDPI
  1. Disable SIP
  2. Run the following script in Terminal
    bash -c "$(curl -fsSL https://raw.githubusercontent.com/xzhih/one-key-hidpi/master/hidpi.sh)"
  3. Follow the instructions, then reboot
  4. Re-enable SIP (if desired)

Or try an alternative method

Enable multimedia keys, fan & LEDs control
  1. Download and install YogaSMC-App-Release.dmg (both the pref-panel and app itself)
  2. Open the app
  3. Check the launch on login option
Use PrtSc key as Screenshot shortcut

Super useful shortcut that I wish I had it on my previous MBP. Default is ⌘⇧5.

  1. Open SystemPreferences.app
  2. Go under Keyboard > Shortcuts > Screenshots
  3. Click on Screenshot and recording options field
  4. Press PrtSc on your keyboard (it should came out as F13)
Use calibrated display profile

NotebookCheck's calibrated profiles. Not all panel are the same, final result may vary.

  1. Run one of the following script in Terminal
    • for 1440p displays
      cd ~/Library/ColorSync/Profiles; wget https://github.com/simprecicchiani/ThinkPad-T460s-macOS-OpenCore/raw/master/Files/DisplayColorProfiles/T460s_WQHD_VVX14T058J02.icm
    • for 1080p displays
      cd ~/Library/ColorSync/Profiles; wget https://github.com/simprecicchiani/ThinkPad-T460s-macOS-OpenCore/raw/master/Files/DisplayColorProfiles/T460s_FHD_N140HCE_EAA.icm
  2. Go under SystemPreferences > Displays > Colour
  3. Select the profile
Add Apple Watch authentication to sudo

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. Apple Watch authenticating with sudo

Monitor temperatures and power consumption
  1. Download and install HWMonitor
  2. Check launch on login (optional)
Faster macOS dock animation

This enables auto-hide and speeds up the animation

  1. 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
Boot process tweaks
Menu Setting What does it do?
Misc Boot ShowPicker False Skip bootloader page
UEFI Audio PlayChime Disabled Always silent boot
Setup hibernation and sleep
[Script](https://www.tonymacx86.com/threads/release-sleeponlowbattery-solb.264785) that performs auto sleep/hibernate at low battery.
  1. Open terminal

  2. Enter commands below one by one

    Settings for AC:

    sudo pmset -c standby 1
    sudo pmset -c hibernatemode 0
    

    Setting for battery:

    sudo pmset -b standby 1
    sudo pmset -b standbydelayhigh 900
    sudo pmset -b standbydelaylow 60
    sudo pmset -b hibernatemode 25
    sudo pmset -b highstandbythreshold 70
    

    Settings for all:

    sudo pmset -a acwake 0
    sudo pmset -a lidwake 1
    sudo pmset -a powernap 0
    

To restore default system settings run

sudo pmset restoredefaults
Advanced energy management

acwake: wake the machine when power source (AC/battery) is changed (value = 0/1)

lidwake: wake the machine when the laptop lid (or clamshell) is opened (value = 0/1)

powernap: enable/disable Power Nap on supported machines (value = 0/1)

standbydelayhigh and standbydelaylow specify the delay, in seconds, before writing the hibernation image to disk and powering off memory for Standby. standbydelayhigh is used when the remaining battery capacity is above highstandbythreshold(has a default value of 50 percent), and standbydelaylow is used when the remaining battery capacity is below highstandbythreshold.

hibernatemode supports values of 0, 3, or 25. To disable hibernation, set hibernatemode to 0.
hibernatemode = 0 by default on desktops. The system will not back memory up to persistent storage. The system must wake from the contents of memory; the system will lose context on power loss.
hibernatemode = 3 by default on portables. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from hibernate image.
hibernatemode = 25 is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery life, you should use this setting.

What's not working ⚠️
  • Some users reported Mini DisplayPort is broken for them with latest updates, but it's working for me just fine
  • Safari DRM Use Chromium engine to watch Apple TV+, Amazon Prime Video, Netflix and others
  • WWAN (needs to be implemented)
  • Fingerprint Reader
  • Bluetooth (You can enable blutooth in the config.plist but it will cause the "volume hash mismatch" problem .Waiting for the solution.
