Hackintoshing your computer is a risky task. This repository is just a reference guide for Lenovo Thinkpad T470s. I'm NOT RESPONSIBLE for any harm you cause to your computer(s).

NOTE: If you want to just copy-paste EFI still, I would recommend you to go through the Opencore Installation Guide.

Prerequisites

• Basic Understanding of command line
• Python installed on your system
• An Internet Connection
• 4GB Pendrive
• Lenovo Thinkpad T470s :)
• No urgent work or some sort of deadlines

Tools We Need

• OpenCore Pkg - Debug version is preffered
• USBToolBox (Optional) - Ports are already mapped
• ProperTree
• GenSMBios

Getting Started

To get started, we'll need to create an installation media for this, we'll need to download macOS .dmg and .chunklist files. so, follow these steps:

2. Extract the OpenCore Pkg
3. cd to OpenCore-[1.0.1]-DEBUG/Utilities/macrecovery
4. Run this command

# Monterey (macOS 12)
py macrecovery.py -b Mac-FFE5EF870D7BA81A -m 00000000000000000 download

Making the Installer using Windows

After the installation completes, we'll make the installation. For this guide, we'll be using windows for installation, if you prefer linux then go with this link

NOTE: if your USB is larger than 16GB use rufus method. Otherwise, use Windows Disk Management

Method 1: Using Rufus

• Open Rufus
• Set Device to YOUR USB DISK
• Set Boot Selection to Non Bootable
• Set Partition Scheme to FAT32
• Set Target System to UEFI
• Click on Start button

Method 2: Disk Managment

• Search Create and format hard disk partition using windows start menu
• Click on Create and format hard disk partition
• Select your USB Drive, right Click on it
• Click on Format

After the Disk is formated, create a new folder/direcotory com.apple.recovery.boot in the root of the USB drive. Now grab BaseSystem.dmg and BaseSystem.chunklist from OpenCore/Utilties/macrecovery and paste these 2 files into com.apple.recovery.boot folder of the USB.

Moreover, clone this repository and copy the EFI folder of this repo into the root of the USB partition. After all of these steps are done now your USB will look like this:

YOUR_USB_DRIVE
│--com.apple.recovery.boot
|   BaseSystem.dmg
|   BaseSystem.chunklist
|
│--EFI
|   |--BOOT
|   |--OC

and there you go, you've made the installer.

Generating SMBIOS

We've successfully made the installer now it's time to generate SMBIOS for our thinkpad to have a working iMessage and facetime so, for this we'll follow the following steps:

1. Extract GenSMBIOS
2. cd to GenSMBios
3. Click on GenSMBios.bat
4. Use option 3 to Generate SMBios
5. Type MacBookPro13,3
6. You'll be presented with information like this

Type:         MacBookPro13,3
Serial:       C02TJJYFGTFN
Board Serial: C02714501QXHCF9JC
SmUUID:       3C931CE2-77B8-440C-A4D2-F4AB6E751A34
Apple ROM:    CC29F51F8589

7. Extract ProperTree
8. cd to Propertree
9. Right click on ProperTree.bat and click on Run as Administrator
10. This will open the propertree, now click on File -> Open
11. Open YOUR_USB_DRIVE/EFI/OC/config.plist
12. Press Crtl + Shift + r
13. Go to PlatformInfo section in propertree

Put the values from the above list to Propertree

• Type Goes to PlatformInfo -> Generic -> SystemProductName
• Apple ROM Goes to PlatformInfo -> Generic -> ROM (Here you Can put your device Mac address as well)
• Board Serial Goes to PlatformInfo -> Generic -> MLB
• SmUUID Goes to PlatformInfo -> Generic -> SystemUUID
• Serial Goes to PlatformInfo -> Generic -> SystemSerialNumber

and now you'll have a working iMessage and facetime

BIOS Settings

We must configure the BIOS to successfully boot & install macOS.

In Security menu, set the following settings:

Security -> Security Chip: must be Disabled
Memory Protection -> Execution Prevention: must be Enabled
Virtualization -> Intel Virtualization Technology: must be Enabled
Virtualization -> Intel VT-d Feature: must be Enabled
Anti-Theft -> Computrace -> Current Setting: must be Disabled
Secure Boot -> Secure Boot: must be Disabled
Intel SGX -> Intel SGX Control: must be Disabled
Device Guard: must be Disabled

In Startup menu, set the following options:

UEFI/Legacy Boot: UEFI Only
CSM Support: No

In Thunderbolt menu, set the following options:

Thunderbolt BIOS Assist Mode: UEFI Only
Wake by Thunderbolt(TM) 3: No
Security Level: No
Support in Pre Boot Environment > Thunderbolt(TM) device: No

And that's it, now go ahead and boot the USB drive and Enjoy!
