Tested with macOS Catalina 10.15.4, but expected to work with Mojave 10.14. This configuration uses OpenCore 0.5.6 - any later releases of OpenCore have not yet been tested so use at your own risk.

This configuration works out the box with iCloud services, but it's highly reccomended to flush a new SMBIOS. Using the included SMBIOS could result in a blacklisted or permanently banned Apple ID.

What is OpenCore?

OpenCore is an open-source unconventional first-in-class piece of software designed to intercept kernel loading to insert a highly advanced rootkit, designed to be an alternative to Clover. OpenCore aims to resolve the constraints and issues imposed by Clover by providing a more versatile and modular system. While OpenCore is primarily designed for Hackintosh systems, it can be used in any scenario where an emulated EFI is needed.
