history

Project history and usage

mas is a macOS command-line interface for the Mac App Store, designed for scripting and automation. It gives package-manager users a way to search, list, install, update, and inspect App Store apps from shell scripts and Brewfiles.

Project history

The mas repository was created in August 2015, and v1.0.0 was released in September 2015 as the initial public release. Early releases quickly added app upgrade and App Store sign-in/sign-out commands, establishing the project's role as a bridge between command-line workflows and Apple's GUI-oriented app distribution system.

The project matured into a Swift-based macOS utility with a man page, `mas --help`, GitHub wiki documentation, and a command table in the README. Recent releases continue to track App Store behavior and macOS compatibility changes; the v6 series improved minimum-OS handling for outdated checks, and GitHub listed v7.0.0 as the latest release in May 2026 with optional JSON output and tabular output improvements.

Adoption history

mas became especially prominent in the Homebrew ecosystem because Homebrew Bundle can include Mac App Store applications in a Brewfile. The official README lists Homebrew Core, the mas tap, MacPorts, and GitHub Releases as installation routes, while the supplied package metadata also records Nix packaging.

With more than twelve thousand GitHub stars, mas is one of the better-known macOS-specific CLI tools. Its adoption reflects a common need among dotfile, laptop-bootstrap, and managed-Mac users: keeping App Store software in the same declarative or scripted workflow as Homebrew packages.

How it is used

Common commands include `search`, `lookup`, `list`, `outdated`, `get`, `install`, `lucky`, `update`, `uninstall`, `open`, and `home`. The README notes that detailed command documentation is available through `man mas` and `mas --help`.

The CLI depends on macOS and App Store behavior rather than a portable service API. Its README documents practical constraints such as App Store eventual consistency, Spotlight indexing requirements, free-app installation behavior, and the need to purchase paid apps directly in the App Store.

Why package nerds care

mas is package-nerd glue: it does not replace Homebrew, but it fills the Mac App Store gap that Homebrew intentionally leaves alone. In Brewfiles, it lets a machine rebuild include both Unix packages and GUI App Store apps.

It is also a useful reminder that package management on macOS is plural. Homebrew, MacPorts, Apple's App Store, and system update mechanisms all own different slices, and mas gives one of those slices a scriptable face.
