BCLM is a wrapper to read and write battery charge level max (BCLM)/CHWA values to the System Management Controller (SMC) on Mac computers. It supports both Intel and Apple silicon. This project was inspired by several battery management solutions, including Apple's own battery health management. The purpose of limiting the battery's maximum charge is to prolong battery health and to prevent damage to the battery. Various sources show that the optimal charge range for the operation of lithium-ion batteries is between 40% and 80%, commonly referred to as the 40-80 rule [1][2][3]. This project is especially helpful to people who leave their Macs on the charger all day, every day.
Features

- Currently, it can only be compiled on macOS Catalina (10.15) or higher but it can run on OS X Mavericks (10.9) or higher
- The SMC can be reset by a startup shortcut or various other technical reasons
