It allows users to inject custom power management data into the operating system, enabling lower idle frequencies, better turbo boost behavior, and improved battery life. An essential, lightweight utility for macOS power users

When macOS boots on an unsupported Intel CPU (e.g., a Coffee Lake i7 on a Z390 motherboard), the system’s native power management driver ( X86PlatformPlugin ) may fail to load correctly. It looks for a CPU it doesn't recognize and, finding no matching profile, defaults to a "safe" but inefficient mode: the CPU either runs at its base clock constantly (killing battery life and generating excess heat) or fails to reach its turbo frequencies (leaving performance on the table). The system becomes a race car stuck in second gear—functional, but far from optimal. Its ease of use, impressive performance, and power-saving
