## Projektgeschichte und Nutzung

brightness is a macOS command-line utility for reading and setting display brightness from scripts or the terminal.

### Projektgeschichte

The nriley/brightness repository was created in February 2014, with release 1.2 published in August 2015. The README describes a focused utility for controlling all internal and some external displays from the command line.

Its maintenance history mirrors macOS display API changes. The README notes that documented APIs worked through macOS 10.12.3, then Night Shift in 10.12.4 required an undocumented method, and Apple Silicon Macs later required another undocumented method.

### Adoptionsgeschichte

brightness became a durable small utility for macOS automation users. It is packaged in Homebrew and MacPorts according to the input package facts, has hundreds of GitHub stars, and Homebrew analytics reported several thousand installs over the prior year at lookup time.

### Wie es verwendet wird

Users run simple commands such as `brightness 1`, `brightness 0.5`, or `brightness -l` to set or list display brightness. The README cautions that displays not controllable through macOS Displays settings generally cannot be controlled by the tool either.

### Warum Paket-Nerds sich dafür interessieren

brightness is the archetypal tiny macOS system utility package: a single-purpose binary that exists because shell scripts and automation tools need access to a GUI-era hardware setting. Its significance is not breadth, but longevity across changing macOS display internals.

### Zeitleiste

- 2015: Release 1.2 published.

### Related projects

- Shell scripts, launch agents, and automation workflows are common consumers of this kind of command-line brightness control.
