Lenovo ThinkPad T440S using OpenCore (0.6.7)
The up to date EFI and the more detailed usage explanation can be found at: https://github.com/Sniki/Lenovo-Thinkpad-T440S
Warning !RESET NVRAM: please do not use this option, there is an issue from Lenovo's side on the 2-3 recent versions of Bios which after NVRAM reset, the Laptop get's bricked and you will have to flash original bios back with a SPI Programmer.
PreparationThe OpenCore EFI that i have provided is completely baked for you, which means all the possibly necessary kexts that may be required, all the Drivers and all the ACPI Patches the config.plist etc are there and configured for use OOB.
So everyone that plans to use this guide, is required to complete these small tweaks to have everything working:
1. SMBIOS values
Note: MacbookPro11,1 is the only SMBIOS that you should use, for that reason it is already set into the config.plist
In order to have iMessages and other iCloud Services make sure to port the values from your Clover config.plist
Open Config.plist of OpenCore EFI with PlistEditPro
Go to config.plist / PlatformInfo / Generic and copy/paste the values from Clover to the OpenCore config.plist file.
Or in case you don't have any IDs from previous setup, you can generate new ones.
For installation there are 3 options that you can try but first make sure you are using latest Clover guide where you have no kext installed into /Library/Extensions or you will have big problems, on my latest Clover guide i have noted that kexts shouldn't be installed into system anymore but EFI/Clover/kexts/Other, so the same principles apply here, all latest kexts are already included into this OpenCore EFI but /Library/Extensions should have no hackintosh kexts there.
Option 1: OpenCore EFI USB
This is the safest way to test it, all you have to do is get a USB drive, format it as HFS+J GPT, mount the USB EFI and copy the EFI of the OpenCore that i attached and simply reboot and boot from USB, you will maintain your installation but instead of your current Clover EFI you boot from the OpenCore EFI from USB.
Option 2: Replace Clover EFI with OpenCore EFI (prefered after Option 1 tested successfully and no problems spotted).
Mount the EFI partition of your HDD/SSD, compress the old EFI (Clover), delete the EFI folder and add the OpenCore EFI, reboot
Option 3: OpenCore USB Installer Same as Option 1 but if you prefer to clean install simply create the USB Installer like you usually do but after USB Installation media has been completed from terminal, mount EFI and place the OpenCore EFI and reboot, boot from USB and start installation.
Problem Reporting and TroubleshootingPlease provide proper Problem Reporting (archive) which includes the EFI and a copy of IOREG.
IOREG should be saved with the correct working version of IOregistryExplorer that can be found here:
