Lenovo ThinkPad X280 - OpenCore Configuation

Status: Maintained (and sorta works)
Version: 1.0

⚠️ Disclaimer

This guide is heavily based on valnoxy's guide for the T480. This is possible due to hardware similarities. Keep in mind that this still isn't perfect and you WILL encounter issues.

This guide is only for the Lenovo ThinkPad X280. I am NOT responsible for any harm you cause to your device. This guide is provided "as-is" and all steps taken are done at your own risk.

The ACPI patches and the style of this README are from EETagent.

Introduction

💻 My Hardware

This is the configuration of my X280, however this configuation should still work with all X280 variants.

Note Check the model of your WiFi & Bluetooth card. Intel cards should be compatible with itlwm (or AirportItlwm). If your card is from another manufacturer, please check if your card supports macOS.

Installation

📝 Requirements

You must have the following items:

a working X280 (obviously);
access to a working Windows machine with Python 3 installed;
a pendrive with more than 4 GB (remember that during the preparation we will format the flash drive to create the installation media, which will wipe all the data currently on it);
an Internet connection (recommended via Ethernet via dongle, but Wi-Fi should work fine);
a few hours to troubleshoot everything. By rushing the install you are bound to fuck something up!

⚙️ Preperation

Create the install media

First of all, you will need an installer of macOS. We'll use macrecovery to download and create the USB drive.

With macrecovery, the process is, as follows:

Download OpenCorePkg as a ZIP.
Extract the OpenCorePkg-master.zip file.
Open cmd.exe with Administrator privileges and change the directory to OpenCorePkg-master\Utilities\macrecovery.
Enter the following command to download macOS 12:

python macrecovery.py -b Mac-E43C1C25D4880AD6 -m 00000000000000000 download

After the download succeeded, type diskpart and wait until you see DISKPART>
Plug-in your pendrive and type list disk to see your disk id.
Select your pendrive by typing select disk <diskid>. Make sure you selected the correct device! Use detail disk to check.
Now, clean the pendrive and convert it to GPT; first, type clean and then convert gpt.

Note: If an error occurred, try to convert again by typing convert gpt.

If your drive is over 32GB, you will encounter issue with the next step - DiskPart can only handle FAT32 formatting for drives up to 32GB, hence to create a FAT32 partition you will need an external tool. I personally recommend minitool's partition wizard. A tutorial for this will be added later. If you follow this path, skip the next step (and ONLY the next step).
After the pendrive is cleaned and converted, create a new partition for the installer and EFI; type create partition primary, then select the new partition with select partition 1 and format it format fs=fat32 quick.
Finally, mount your pendrive by typing assign
Now, close the Command Prompt and copy the folder com.apple.recovery.boot (with its contents) from OpenCorePkg-master\Utilities\macrecovery onto the root the pendrive.

After the install media was created, you need to make the USB drive bootable.

Configure and install OpenCore

Download the EFI folder from this repo, download the repo as a .zip and drag the EFI folder onto the root of your pendrive.

GenSMBIOS

To configure your SMBIOS, you need to use GenSMBIOS. The tool will automatically generate a fake serial number, UUID and MLB for you. This step is essential to have working iMessage, so do not skip it!

Download GenSMBIOS as a ZIP, then extract it.
Start GenSMBIOS.bat and use option 1 to download MacSerial.
Choose option 2, to select the path of the config.plist file. It will be located in EFI -> OC folder on your pendrive.
Choose option 3, and enter MacBookPro15,2 as the machine type.
Press Q to quit. Your config now should contain the requied serials.

Enter the proper ROM value

After adding serials to your config.plist, you have to add the computer's MAC address to the config.plist file. This step is also essential to have a working iMessage, so do not skip it. We need a .plist editor to write the MAC address into the config.plist file. I recommendProperTree as it works on Windows. You have to change the MAC address value in the config.plist at

PlatformInfo -> Generic -> ROM

Delete the generic 123456789012 value, and enter your MAC address into the field, without any colons. You can get this address on Windows and Linux by following the linked tutorials. Save the .plist file by pressing Ctrl+S.

Default keyboard layout and language

The default keyboard layout and language is Polish. To change the language, edit the value of NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> prev-lang:kbd to the value of your language. This part is a bit complicated; if your value contains an underscore "_", replace it with a hyphen "-". The value for English would be en-US:0. You can find a list of all language values here. For example, if you were to pick Portugese, the value in this file is [10] pt_PT - Portuguese - hence, the value that you need to put in your .plist would be pt_PT:10.

Install OpenCore

If you followed all the steps correctly and copied the EFI folder before, OpenCore should already be installed and ready to boot.

🚚 Installation

Prepare BIOS

The bios must be properly configured prior to installing 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: Disabled. Do NOT set this to anything else, as it is known to cause potential bricks on the X280, which you won't be able to fix at home!
Wake by Thunderbolt(TM) 3: No
Security Level: No
Support in Pre Boot Environment > Thunderbolt(TM) device: No

Now you can go through the install.

Install macOS

Boot from USB, press SPACE and select the USB drive inside of OpenCore "NO NAME (DMG)" or similar.

Note: The first boot may take up to 20 minutes.

Wait for the macOS Utilities screen.
Connect to your network if using Wi-Fi.
Select Disk Utility, select your disk and click erase. Give a name and choose APFS with GUID Partition Map.
After erasing, go back and select Reinstall macOS and follow the steps on your screen. The installation make take up to 2 hours, in my case with a 300Mbps download connection it took around an hour.

Note: Your PC will restart multiple times. If this happens (and it will), just boot from USB again and select your disk inside of OpenCore. It will be named either macOS Installer or the name you picked when formatting the drive.

Once you see the Region selection screen, you are good to proceed.
Create your user accound and everything else. You should be able to log in with iCloud if you generated your SMBIOS correctly and changed the MAC address.

♻️ Upgrade macOS / Switch EFI

If you want to upgrade macOS, download the desired macOS version in the Settings app and simply perform the upgrade like on a real Mac; however, if you plan to upgrade your EFI, you'll need a different OpenCore configuation.

Note: Download the desired macOS version in the Settings before following these steps, if you are connected via WiFi.

Download the newest release & ProperTree and extract it.
Start ProperTree and load the Config.plist on your EFI partition. (File -> Open)

Note: You can mount your EFI partition by pressing ALT + SPACE, typing Terminal and enter the following command: sudo diskutil mountDisk disk0s1.

Now also load the new configuration file from the repo for the desired macOS installation (or HeliPort config).
You should now have 2 ProperTree-windows open on your screen.
Go in both windows to Root -> PlatformInfo -> Generic. Transfer MLB, ROM, SystemProductName, SystemSerialNumber and SystemUUID to the new config.
Save the new config (File -> Save) and close both windows.
Now delete your existing EFI folder from the EFI partition and copy the new one to it. (Make sure that the Directorys Boot and OC are in EFI).

Post-install (optional)

💾 Install OpenCore to Hard Drive (recommended)

Press ALT + SPACE and open terminal. Type sudo diskutil mountDisk disk0s1 (where disk0s1 corresponds to the EFI partition of the main disk - disks can be listed using the command sudo diskutil list, but most likely it will be disk0s1)
Open Finder and copy the EFI folder of your USB device to the main disk's EFI partition.
Unplug the USB device and reboot your laptop. Now you can boot macOS without your USB device.

✏️ Create a offline install media (Optional)

In case of reinstalling macOS, having a full system installer on your USB drive. You also don't need internet connection for the installation. To create a offline install media, you need the following stuff:

macOS Installer from the App Store.
A 16 GB+ pendrive (Keep in mind, during the preperation we will format the disk to create the install media).

Download the installer from App Store. Press ALT + SPACE and open Disk utility. Select your USB device and click erase. Name it MyUSB and choose Mac OS Extended with GUID Partition Map. After erasing the USB device, close Disk utility.

Now press ALT + SPACE and open terminal. Type the following command:

Big Sur: sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB --downloadassets

Monterey: sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB --downloadassets

After creating the install media, copy your EFI folder to the EFI partition of your USB device.
