If you are part of the Hackintosh community or trying to squeeze extra life out of an older Mac, you have likely encountered the terms "power management" and "frequency scaling." By default, macOS makes generic assumptions about how your CPU should behave to balance performance and battery life. , a open-source kernel extension (kext) developed by the Acidanthera team (the same group behind Lilu and WhateverGreen), is designed to override these assumptions.
By combining these, the user creates a tailored solution. For example, if a Hackintosh uses an Intel Core i7-8700K, the user can source frequency vectors from a genuine 2018 Mac mini (which uses the i7-8700B, a nearly identical chip). CPUFriend then ensures that macOS applies the correct turbo ratios, EPP (Energy Performance Preference) values, and idle sleep states to the desktop CPU. The result is that the foreign chip behaves, from the OS’s perspective, exactly like an Apple-sanctioned one. cpufriend
In the world of personal computing, the operating system is often described as the "soul" of the machine, while the hardware is its "body." For users of genuine Apple hardware, this soul and body are meticulously tuned to work in perfect harmony. However, for Hackintosh users—those who run macOS on standard, off-the-shelf PC components—this harmony is not guaranteed. The kernel and power management frameworks of macOS are written with Apple’s specific silicon in mind. Enter , a lightweight but profoundly important kernel extension (kext) that acts as a translator and diplomat, ensuring that a foreign CPU can be understood and managed efficiently by a native macOS system.

Understanding CPUFriend: The Key to Native Power Management CPUFriend is an open-source, highly efficient Lilu plugin developed by the Acidanthera group. It acts as a dynamic processor-topology and power-management-data injector for macOS kernels. The primary objective of this kernel extension (kext) is to modify frequency vectors on non-native x86 hardware. This ensures that custom PC builds or unsupported hardware run with optimized power curves, correct sleep states, and predictable thermal throttling.
