We use script 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 MacBookPro15,2 as the machine type.
• Press Q to quit. Your config now should contain the requied serials.

Using Plist editor ProperTree to add serials and 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. 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 media.

It's possible to bypass opencore acpi booting process, following steps:

1. Download OpenCore Source Code zip package;
2. unzip OpenCore Source Code;
3. copy patch_no_acpi.py to root directory of OpenCore Source Code;
4. cd ${OC_Source_Code_Root_Directory}, run patch_no_acpi.py;
5. build OC using build_oc.tool;

It's possible to unlock Advanced menu thus disable CFG Lock natively in UEFI + Other Advanced menu benefits. SPI Programmer CH341a is required, and following Unlock BIOS Advanced Menu to flash BIOS.
