To Use

0. Clone this repo:

$ git clone https://github.com/Lacedaemon/Thinkpad-L450-OpenCore

1. Per the [Repo]/EFI/OC/config.plist, download the corresponding version of OpenCore.

• If the version used in this repo is newer than the latest prebuilt release, OpenCore must be compiled from source:

$ git clone https://github.com/acidanthera/OpenCorePkg
$ cd [path to cloned repo]
$ ./macbuild.tool

2. From the downloaded OpenCore package, extract the following files to their respective places in the cloned repo:

• [OpenCore]/EFI/BOOT/BOOTx64.efi -> [Repo]/EFI/BOOT/BOOTx64.efi
• [OpenCore]/EFI/OC/OpenCore.efi -> [Repo]/EFI/OC/OpenCore.efi
• [OpenCore]/EFI/OC/Drivers/OpenRuntime.efi -> [Repo]/EFI/OC/Drivers/OpenRuntime.efi
• [OpenCore]/EFI/OC/Drivers/OpenCanopy.efi -> [Repo]/EFI/OC/Drivers/OpenCanopy.efi

3. Download and extract the latest compatible ApfsDriverLoader.efi from AppleSupportPkg to [Repo]/EFI/OC/Drivers.
4. Download and copy the latest compatible HfsPlus.efi from OcBinaryData to [Repo]/EFI/OC/Drivers.
5. Follow the README's in the [Repo]/EFI/OC/ACPI and [Repo]/EFI/OC/Kexts folders.
6. Generate new SMBIOS data with GenSMBIOS. Refer to the vanilla guide linked below for the full procedure.
7. Copy the finished [Repo]/EFI folder to a FAT32 partition (e.g. a USB drive or EFI System Partition), then boot from it.
