Download for Mac

Requires a Mac with Apple silicon and macOS 27 or later. 16 GB of memory is recommended. This is version 0.1.9: see what's new. Release notes and checksums are on GitHub.

Getting started

  1. Open the downloaded file and drag Editor Harness to Applications, or double-click it to install and open it in one go. macOS asks before it opens an app downloaded from the internet: choose Open.

  2. Choose where to keep your work: make your first Library, or open one you have. A Library is one file in Finder that keeps your projects, in your Movies folder unless you choose another place.

  3. In the Welcome window, connect the assistant you use on this Mac, such as the Claude app, Claude Code or Codex. It works in every project, and other assistants that support MCP connect in Settings ▸ Assistants.

  4. Choose your footage folder and paste the request into your assistant. It makes the project in your Library and brings your footage in.

  5. Tell your assistant what you want, and keep the edits you like. Sign in when you're ready to export: your free trial starts then.

Editor Harness keeps itself up to date. Updates download and install in the background.
