Mac Manager

Monitor your Mac's health, security and hardware from the terminal — battery alerts, live dashboard, security audit and dev-tooling inventory.

A Python CLI to monitor and take care of your MacBook (Apple Silicon) right from the terminal — battery, system, disk, network — with a live dashboard, automatic daily logging, and native notifications to preserve battery health.

Designed for Apple Silicon MacBook Air/Pro. It also works on Intel, but some metrics (battery capacity, etc.) may vary.

Installation

Homebrew (recommended)

brew install armelingu/tap/mac-manager

The formula lives at armelingu/homebrew-tap. You can also brew install --HEAD armelingu/tap/mac-manager to track the latest commit on main instead of the released version.

pipx / pip

pipx install mac-manager   # isolated, recommended
# or
pip install --user mac-manager

After installation, the mm command is on your PATH.

pipx/pip installs give you the CLI only. The background launchd agents (daily log + battery alerts) are set up by the source install below, or you can register them manually later.

From source

git clone https://github.com/armelingu/mac-manager.git
cd mac-manager
./install.sh

This will:

• create a local venv in .venv/
• install rich and psutil
• create the symlink ~/.local/bin/mm
• register two launchd agents:
  • daily log at 09:00 → writes a snapshot to ~/Library/Application Support/mac-manager/battery.csv
  • battery alerts every 15 min → native macOS notification

Make sure ~/.local/bin is in your PATH:

echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Commands

For the complete reference for each command (description, options, when to use, examples), see COMMANDS.md.

Hardware and system

Battery — history

Security

Development

Smart alerts

To preserve the lithium-ion battery (every cycle counts!), the agent checks every 15 min and fires a notification:

• ≥ 80% charging → "consider unplugging" (every 2h)
• ≤ 20% on battery → "good time to plug in" (every 30min)
• ≤ 10% on battery → critical alert (every 10min)
• health < 80% → 1x per week

History

Every day at 9 AM, a snapshot is written to ~/Library/Application Support/mac-manager/battery.csv:

timestamp,percent,is_charging,power_source,cycle_count,max_capacity_mah,design_capacity_mah,health_percent,temperature_c
2026-04-19T09:00:01,82,1,AC Power,12,4350,4380,99.3,30.5

In a few months you can plot the real degradation of your Mac.

Uninstallation

./uninstall.sh

Removes launchd agents, symlink and venv. Preserves battery history in ~/Library/Application Support/mac-manager/.

Status

Mac Manager is currently in alpha: the public CLI surface is stabilizing, breaking changes can still happen between 0.x releases without a deprecation window. Once we ship 1.0.0, every breaking change will follow Semantic Versioning and a deprecation cycle.

Changelog

All notable changes are documented in CHANGELOG.md, following the Keep a Changelog format.

Releasing

Maintainers: see RELEASING.md for the full release runbook (SemVer policy, version bump, tagging and the tag-driven GitHub Actions pipeline that builds artifacts and cuts a GitHub Release automatically — PyPI publication is wired with Trusted Publishing and can be activated by flipping a single flag).
