DictUnifier

DictUnifier is a utility for macOS that converts dictionary files used by the system’s built‑in dictionary application. It works on macOS 10.5 and later, allowing users to transform dictionaries between supported formats so they can be imported into or exported from the system dictionary database. The tool is distributed as a zip archive for macOS 2.1 and can be built from source after installing a static build of glib via Homebrew.

The software targets users who need to manage custom or third‑party dictionary data on their Mac, such as developers, linguists, or anyone who wants to add specialized word lists to the OS dictionary service. Its command‑line interface processes dictionary files in batch, handling the conversion without requiring a graphical front end.

DictUnifier is considered stable and is actively maintained on GitHub, where contributors can submit pull requests. Future work includes removing the glib dependency and expanding support for additional dictionary formats.
