Install RigOne, check that the download is genuine and open it for the first time.
What you need
- A Mac with Apple Silicon and macOS 13 or later.
- At least one agent app, installed and signed in: Claude Code, Codex or OpenCode. RigOne starts these programs for you; it does not replace them, and runs use your own plan with each vendor.
- A project folder on this Mac — usually a Git repository — for the agents to work in.
Install
- Download
RigOne_<version>_aarch64.dmgfrom the latest release. - Open the DMG and drag RigOne into Applications in the install window.
- Open it from Applications.
The disk image and the application inside it are both signed with Apple Developer ID, notarized and stapled. If macOS says the app "cannot be opened" or "is damaged", do not work around it: delete the file, download it again, and open an issue if it happens again.
Verify the download
Each release lists the SHA-256 of its DMG and carries a SHA256SUMS.txt. In Terminal:
shasum -a 256 ~/Downloads/RigOne_<version>_aarch64.dmg
spctl --assess --type open --context context:primary-signature -v ~/Downloads/RigOne_<version>_aarch64.dmg
The first line must match the checksum in the release notes. The second must answer accepted
and source=Notarized Developer ID.
First launch
On first launch RigOne asks your agent apps for their versions. The account button at the bottom of the sidebar carries a green dot when Claude Code or Codex answers, and Settings → Health check lists everything RigOne needs, with a button to fix what does not work. An empty RigOne opens on a new task and says in words what each place is waiting for.
macOS asks for each permission the first time it is needed: access to the folders you work in, sending events to other applications, the microphone if a workflow drives an app that records, and notifications, which RigOne uses when a decision waits for you while it is in the background.
The interface follows the macOS language. RigOne speaks English, Polish, German, Spanish, French, Italian, Portuguese, Chinese and Japanese; choose another in Settings → Appearance. What agents and the engine write in a run stays in English, and this guide uses the English names of buttons and screens.
