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. ### 采用历史 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. ### 使用方式 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. ### 为什么软件包爱好者会关心 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. ### 时间线 - 2014: Repository created. - 2015: Release 1.2 published. - 2017: README documents the macOS 10.12.4 Night Shift-era API break and workaround. - 2021: Repository history includes Universal 2 build work for Apple Silicon. - 2026: Homebrew stable version reported as 1.2. ### Related projects - Homebrew and MacPorts distribute brightness for macOS users. - macOS display APIs and IOKit-style display enumeration are the system interfaces around which the utility operates. - Shell scripts, launch agents, and automation workflows are common consumers of this kind of command-line brightness control. ### 来源 - - - - source_facts.package-manager ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## 源数据库详情 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** brightness - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Requirements:** macos - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 其他软件包管理器记录 - MacPorts - brightness: normalized package name match | MacPorts ports tree: sysutils/brightness/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 相关链接 - [Source-control packages](https://pkg.so/zh-hans/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/zh-hans/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/zh-hans/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://pkg.so/zh-hans/brew-utility-packages/) - Matched Homebrew package provider. - [screenresolution](https://pkg.so/zh-hans/brew/screenresolution/) - Shares pkgdb curated category or tags: cli, display, macos, system. - [redshift](https://pkg.so/zh-hans/brew/redshift/) - Shares pkgdb curated category or tags: cli, display, system. - [lcdproc](https://pkg.so/zh-hans/brew/lcdproc/) - Shares pkgdb curated category or tags: cli, display, system. - [libxcvt](https://pkg.so/zh-hans/brew/libxcvt/) - Shares pkgdb curated category or tags: cli, display, system. - [displayplacer](https://pkg.so/zh-hans/brew/displayplacer/) - Shares pkgdb curated category or tags: cli, display, macos, system. - [switchaudio-osx](https://pkg.so/zh-hans/brew/switchaudio-osx/) - Shares pkgdb curated category or tags: cli, macos, system, system-utility. - [m-cli](https://pkg.so/zh-hans/brew/m-cli/) - Shares pkgdb curated category or tags: cli, macos, system, system-utility. - [mist-cli](https://pkg.so/zh-hans/brew/mist-cli/) - Shares pkgdb curated category or tags: cli, macos, system, system-utility. - [ddcctl](https://pkg.so/zh-hans/brew/ddcctl/) - Local package facts share a topical domain.
