# mac-brightness — Screen Brightness Control

Adjusts Mac screen brightness using the `brightness` CLI tool (installed via Homebrew).

## Prerequisites

```bash
brew install brightness
```

## Usage

```bash
# Set brightness to 50%
python3 mac_brightness.py 0.5

# Set brightness to max
python3 mac_brightness.py 1.0

# Set brightness to minimum (not off)
python3 mac_brightness.py 0.1
```

The `level` argument accepts a float between `0` (off) and `1` (full brightness).

## How it works

The script calls the `brightness` CLI tool via `subprocess.run(["brightness", level])`. If the tool is not installed, it prints an error prompting `brew install brightness`.

## Error handling

- **Missing tool**: prints `❌ 请先安装: brew install brightness` — install with `brew install brightness`
- **Out of range**: values outside 0–1 are rejected with a message
