It wraps standard macOS disk-image tooling with options for Finder window layout, icons, background images, Applications drop links, encryption, signing, and notarization. ### Project history The project README credits Andrey Tarantsov as the original creator and says Andrew Janke helped substantially with the project in May 2020. The project is maintained as a shell script in a public GitHub repository under the create-dmg organization. ### Adoption history The README documents Homebrew installation as the first installation path, followed by release downloads and cloning the repository. That distribution style made create-dmg convenient for macOS developers who wanted repeatable DMG creation in release scripts without maintaining their own AppleScript and hdiutil wrappers. ### How it is used The normal workflow is to run create-dmg with an output .dmg name and a source folder, then pass options for volume name, icon placement, background art, filesystem format, encryption, codesigning, notarization, and related macOS packaging details. ### Why package nerds care For package maintainers, create-dmg matters because DMG layout is a macOS distribution detail that is easy to get wrong and awkward to reproduce. The tool packages common release-engineering conventions into one script that Homebrew, MacPorts, and Nix can expose as a small CLI dependency. ### Timeline - Original project: Created by Andrey Tarantsov - 2020-05: README notes substantial help from Andrew Janke - README: Documents Homebrew installation and release-download installation ### Related projects - The README lists node-appdmg and dmgbuild as alternatives for building macOS disk images. ### Sources - ## Security Notes generalized runtime or code generation signal. - **Geiger risk:** yellow / medium - generalized runtime or code generation signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** create-dmg - **Version Scheme:** 0 - **Revision:** 0 - **Requirements:** macos - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - create-dmg: normalized package name match | nixpkgs package indexes: pkgs/by-name/cr/create-dmg/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - MacPorts - create-dmg: normalized package name match | MacPorts ports tree: sysutils/create-dmg/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Package publisher tools](https://www.automicvault.com/pkg/package-publishers/) - Belongs to a package publishing or registry command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [abi3audit](https://www.automicvault.com/pkg/brew/abi3audit/) - Shares av.db curated category or tags: cli, developer-tools, packaging. - [cargo-bundle](https://www.automicvault.com/pkg/brew/cargo-bundle/) - Shares av.db curated category or tags: cli, developer-tools, packaging. - [charmcraft](https://www.automicvault.com/pkg/brew/charmcraft/) - Shares av.db curated category or tags: cli, developer-tools, packaging. - [dylibbundler](https://www.automicvault.com/pkg/brew/dylibbundler/) - Shares av.db curated category or tags: cli, developer-tools, macos, packaging. - [flit](https://www.automicvault.com/pkg/brew/flit/) - Shares av.db curated category or tags: cli, developer-tools, packaging. - [hpack](https://www.automicvault.com/pkg/brew/hpack/) - Shares av.db curated category or tags: cli, developer-tools, packaging. - [makepkg](https://www.automicvault.com/pkg/brew/makepkg/) - Shares av.db curated category or tags: cli, developer-tools, packaging. - [makeself](https://www.automicvault.com/pkg/brew/makeself/) - Shares av.db curated category or tags: cli, developer-tools, packaging, shell. - [create-api](https://www.automicvault.com/pkg/brew/create-api/) - Package names and metadata indicate a similar tool family.
