Energy settings are crucial for optimizing the performance and battery life of your Apple devices. On macOS, managing these settings can help you extend the battery life of your MacBook, reduce energy consumption, and ensure that your system runs efficiently. While Windows systems use tools like Power Options for energy management, macOS offers its own set of tools and settings to achieve similar results. This article will guide you through the process of configuring energy settings on macOS, including practical examples and commands.
