Install Hermes Agent on macOS

Short answer

Install Hermes Agent on macOS only after checking the official installation page and repository. The official docs list a one-line CLI installer for Linux, macOS, and WSL2, plus desktop downloads through GitHub releases.

The first success signal is simple: a new terminal can run hermes or hermes --help, and you know where Hermes stores its data before you connect real projects.

Prerequisites

• A macOS account where you are comfortable installing developer tooling.
• A current terminal session and a second new terminal for PATH verification.
• Git available if using the git-based installer.
• A non-sensitive test directory for the first agent session.
• No production provider keys until the command and data directory are verified.

Command to verify against official docs

This command is shown here for orientation. Before running it, open the official installation guide and confirm the current command and requirements.

# Copy from official docs after review
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash

# Open a new shell, then check
hermes --help
hermes doctor

Expected outputs

• The installer completes without a command-not-found error.
• A new shell can resolve the hermes launcher.
• hermes doctor gives useful diagnostics or a clean environment report.
• Provider setup is deferred until the first local command succeeds.

Common failures and fixes

Security notes

• Run the first session inside a test directory, not your home directory.
• Do not paste API keys into screenshots or issue reports.
• Use Docker if the workflow will execute commands against sensitive repositories.
• Back up important local config before making Hermes part of a daily workflow.

Agent Guide judgment

macOS is the fastest evaluation path for many operators, but speed is the risk: it is easy to install in the same account that holds personal files, client repositories, browser sessions, and provider keys.

The first macOS run should happen in a disposable folder with no real secrets. Move to Docker if the workflow will execute commands against serious repositories.

macOS smoke test

1. Verify the installer command against official docs.
2. Open a new terminal and confirm hermes --help works.
3. Run hermes doctor and save only sanitized output.
4. Test in a temporary folder before pointing Hermes at work projects.

macOS gateway PATH trap

The FAQ calls out a practical macOS failure mode: launchd services inherit a minimal PATH. If Node.js, ffmpeg, Homebrew tools, or user-installed CLIs work in Terminal but fail under the gateway, re-snapshot the gateway environment instead of reinstalling Hermes.

Direct answer

On macOS, use the official installer or desktop release path, then open a new shell and verify hermes before adding providers, gateways, MCP servers, or sensitive project folders.
