Install & Requirements

Download

Download the latest .dmg from the GitHub Releases page, open it, and drag Manifold to Applications.

Requirements

Requirement	Notes
macOS	The packaged app and build scripts currently target macOS only.
Git	Required for repository management, worktrees, diffs, commits, and pull request flows.
One supported CLI agent on your PATH	Manifold checks for the runtime binaries directly.
GitHub CLI (gh)	Optional, but required for creating pull requests from inside the app.
Ollama + at least one pulled model	Optional, only needed for the Ollama-backed runtimes.

Verify your setup

Before launching Manifold, confirm the prerequisites are reachable from your shell:

git --version            # any recent Git
gh --version             # optional, needed for pull request creation
claude --version         # or: codex --version / gemini --version / copilot --version

If a runtime command is not found, install it (see Runtimes & Setup) and make sure its binary is on your PATH.

PATH on macOS

On startup, Manifold reads the PATH from your shell profile and appends common binary directories like ~/.local/bin, /opt/homebrew/bin, and /usr/local/bin, so CLIs installed via Homebrew or similar tools are found even when Manifold is launched from Finder.
