zackelia/bclm

This system is a macOS utility named BCLM that manages battery charge limits by reading and writing SMC keys. It supports architecture-specific constraints for x86\_64 and Apple Silicon Macs and provides commands to persist these settings across reboots via a LaunchDaemon. The project includes integration tests to verify command functionality and argument parsing capabilities.

The Sources directory now contains the BCLM (Battery Charge Level Max) utility, replacing the previous placeholder. This tool allows users to read and write battery charge limits via SMC keys, with architecture-specific behavior: x86\_64 Macs accept values between 50–100, while Apple Silicon Macs accept only 80 or 100. The utility adds \persist\ and \unpersist\ subcommands to manage a LaunchDaemon plist, ensuring the charge limit is restored after reboots. It also handles missing keys gracefully on USB-C Macs by ignoring non-existent BFCL keys during writes.

Sources · high confidence

The test suite now includes comprehensive functional tests for the bclm tool. These tests verify that reading and writing BCLM values works correctly, including validation of invalid inputs (0, 101, and 79 on Apple Silicon). Additionally, the suite tests the persist and unpersist functionality, ensuring that the launch daemon plist is correctly created, removed, and detected via launchctl, while also handling edge cases like double-persisting or double-unpersisting.

Tests · high confidence

The project now includes the swift-argument-parser library (version 0.1.0) as a dependency, enabling command-line argument parsing capabilities for the bclm target.
