Migrate to Version 1.5.0

The Version 1.5.0 changes the model from MacBookPro11,1 to MacBookPro12,1. You need to generate a new SMBIOS for the new model with GenSMBIOS.

EFI	Description	Type
EFI - Catalina	Supports only macOS Catalina	Stable
EFI - Big Sur	Supports only macOS Big Sur	Stable

📖 Usage

📝 Requirements

You must have the following stuff:

• Lenovo ThinkPad T440p (Obviously 😁).
• Access to a working Windows machine with Python installed.
• A pendrive with more than 4 GB (Keep in mind, during the preperation we will format the disk to create the install media).
• an Internet connection via Ethernet.
• 1-2 hours of your time.

⚙️ Preperation

---

Note: If you want to install macOS Monterey, you need to upgrade from Big Sur, or create an offline install media (see down below).

Create the install media

First of all, you will need the install media of macOS. I will use macrecovery to download and create the macOS Install media.

With macrecovery, the process is the following:

• 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:

# Catalina (10.15)
python macrecovery.py -b Mac-00BE6ED71E35EB86 -m 00000000000000000 download

# Big Sur (11)
python macrecovery.py -b Mac-42FD25EABCABB274 -m 00000000000000000 download

# Monterey (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>

• Now we are gonna 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.

• After the pendrive is clean and converted, we will create a new partition where we can put our files on. First, 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 letter=J

• Now, close the Command Prompt and create the folder com.apple.recovery.boot on the pendrive. Copy OpenCorePkg-master\Utilities\macrecovery\BaseSystem.dmg and Basesystem.chunklist into that folder.

Note: If you can't find BaseSystem.dmg, use RecoveryImage.dmg and RecoveryImage.chunklist instead.

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

Configure and install OpenCore

Download the EFI folder from this repo, you will find the latest files under the release tab or just download the repo as it is. Move the folder to the root of your pendrive (e.g. J:) and rename the folder to EFI.

GenSMBIOS

We need a script, called GenSMBIOS, to create fake serial number, UUID and MLB numbers. This step is essential to have working iMessage, so do not skip it!

The process is the following:

• 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.
• Choose option 3, and enter MacBookPro12,1 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 editior, to write the MAC address into the config.plist file. I used ProperTree, since it works on Windows too. You have to change the MAC address value in the config.plist at

PlatformInfo -> Generic -> ROM

Delete the generic 112233445566 value, and enter your MAC address into the field, without any colons. Save the Plist file, and it is now ready to be written out to the EFI partition of your install media.

Default keyboard layout and language

The default keyboard layout and language is German. To change the language, edit the value of NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> prev-lang:kbd to the value of your language. You can find a list of all language values here.

Install OpenCore

After you've finished with the neccesary tweaks, you have to copy the EFI folder to the EFI partition of your pendrive.

🚚 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
• Internal Device Access > Bottom Cover Tamper Detection: must be Disabled
• Anti-Theft > Current Setting: must be Disabled
• Anti-Theft > Computrace > Current Setting: must be Disabled
• Secure Boot > Secure Boot: must be Disabled

In Startup menu, set the following options:

• UEFI/Legacy Boot: Both
• UEFI/Legacy Priority: UEFI First
• CSM Support: Yes

Now you can go through the install.

Install macOS

1. Boot from USB and select the USB drive inside of OpenCore.

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

2. Wait for the macOS Utilities screen.
3. Select Disk Utility, select your disk and click erase. Give a name and choose APFS with GUID Partition Map.
4. After erasing, go back and select Reinstall macOS and follow the steps on your screen. The installation make take up to 2 hours.

Note: Your PC will restart multiple times. Just boot from USB and select your disk inside of OpenCore. (named macOS Installer or the disk name).

5. Once you see the Region selection screen, you are good to proceed.
6. Create your user accound and everything else.

🚚 Post-Install

---

Install EFI

1. Press WIN + SPACE and open terminal. Type sudo diskutil mountDisk disk0s1 (where disk0s1 corresponds to the EFI partition of the main disk)
2. Open Finder and copy the EFI folder of your USB device to the main disk's EFI partition.
3. Unplug the USB device and reboot your laptop. Now you can boot macOS without your USB device.

Fix Audio Jack noise

1. Copy ALCPlugFix to your desktop.
2. Press WIN + SPACE and open terminal. Type the following commands:

sudo spctl --master-disable
sudo mkdir /usr/local/bin/
cd Desktop/ALCPlugFix
./install.sh

3. After that, type hda-verb 0x1a SET_PIN_WIDGET_CONTROL 0x24.

Create a offline install media (Optional)

In case of reinstalling macOS, a offline install media can save some time. You also don't need an Ethernet 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).

Press WIN + 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 WIN + SPACE and open terminal. Type the following command:

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

Catalina: sudo /Applications/Install\ macOS\ Catalina.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.

♻️ Upgrade macOS / Switch EFI

---

If you plan to upgrade your macOS (or updating the EFI / switching to HeliPort), you'll need a different OpenCore configuation (EFI). Please follow these steps:

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

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

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

3. Now also load the new configuration file from the repo for the desired macOS installation (or HeliPort config).
4. You should now have 2 ProperTree-windows open on your screen.
5. Go in both windows to Root -> PlatformInfo -> Generic. Transfer MLB, ROM, SystemProductName, SystemSerialNumber and SystemUUID to the new config.
6. Save the new config (File -> Save) and close both windows.
7. 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).

If you want to upgrade macOS, download the desired macOS version in the Settings app and perform the upgrade like on a real Mac.
