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.

  1. Save and reboot the system
How to update the bootloader
  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

Post-install (optional)

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

Note: The drivers provided in this repo are for Big Sur 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
  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
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/fewtarius/CPUFriendFriend; cd CPUFriendFriend; chmod +x ./CPUFriendFriend.command; ./CPUFriendFriend.command
  1. When asked, select preferred values
  2. From the pop-up window, copy ssdt_data.aml into /EFI/OC/ACPI/ folder (rename it if you'd like)
  3. Open /EFI/OC/Config.plist with any editor
  4. Add the content of #cpu-pm.plist (make sure SSDT-PLUG.aml is disabled and match your new SSDT filename)
  5. 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.

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)

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

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
Speed-up boot process
Menu Setting What does it do?
Misc Boot ShowPicker False Skip bootloader page
UEFI Audio PlayChime False Always silent boot
BIOS Mod

I know it can be scary at first but with the right amount of carefulness anyone can do it.
Is it worth the effort and risk? I don't think so. I enjoyed it? 100%.
