Hermes Agent on Mac: Beginner Install Guide
Goal: install Hermes with the official Hermes Desktop installer, choose a simple model-provider path, confirm Hermes answers, and stop before you over-configure.
This guide updates the older terminal-first Mac guide. The new beginner path is Hermes Desktop Application first. Terminal commands remain as fallback and verification tools, not the default route for a non-technical customer.
Best default: download the Hermes Desktop installer from https://hermes-agent.nousresearch.com/, run it on your Mac, connect model access on first launch, then prove one useful chat before adding advanced tools.
What you install
Hermes Desktop, the local app experience for chatting with Hermes Agent on your Mac.
What Hermes needs
A model provider so Hermes can answer. The simplest beginner route is the login/OAuth path if available.
What success means
You can open Hermes, ask a practical question, and receive a useful answer without troubleshooting.
Step 01
Before you start
Confirm these basics before installing:
You are on a Mac you control.
You know your Mac login password.
You have reliable internet.
You can download and open apps from the web.
You have or can create a model-provider account.
You can receive email/login verification codes.
You will not paste passwords, API keys, bank data, health data, or private customer records into test prompts.
You can monitor billing if you choose an API-key provider.
Step 02
Choose the beginner path
Path
Use when
Beginner note
Hermes Desktop installer
You want the easiest Mac install.
Recommended. Installs the desktop and command-line experience without starting in Terminal.
Command-line installer
The desktop path is unavailable or support tells you to use it.
Fallback. Use Terminal only when the app path does not fit.
Manual/developer setup
You are developing Hermes itself.
Not a beginner path.
Step 03
Install Hermes Desktop on Mac
Check Apple’s developer tools, download Hermes Desktop, then choose model access when Hermes opens for the first time.
3A. Check Apple Command Line Tools and Apple Git
Run each command separately in Terminal. Using xcrun prevents an older incompatible Git from overriding Apple’s working Git.
Check the selected tools
xcode-select -p
Check Apple Git
xcrun git --version
GO: Continue only when the first command shows a developer path and the second shows a clean git version line.
If Apple’s tools are missing, run:
xcode-select --install
Click Install, accept Apple’s license, wait for completion, then repeat both checks.
If plain git --version says “Bad CPU type”
An older incompatible Git is being found before Apple Git. Do not delete files or edit startup profiles. Run these commands separately. PATH must be uppercase.
Continue only if the path points inside Apple’s developer tools and a clean Git version appears. This change lasts only for the current Terminal window.
Click Download for macOS and open the downloaded installer.
If macOS blocks it, use System Settings → Privacy & Security to approve it—but only if it came from the official site above.
Follow the normal installation prompts, then open Hermes Desktop.
The Desktop installer may complete without asking setup questions. Model access is requested when Hermes opens for the first time.
3C. Choose the access you already have
The first screen says, “Let’s get you setup with Hermes Agent” and asks you to connect a model provider. Current choices include:
First-launch choice
Beginner guidance
ChatGPT or Codex Subscription
SAGE9AI beginner recommendation if you already use ChatGPT or Codex. It uses the device-code steps below.
xAI Grok
Use if you have eligible SuperGrok or X Premium+ access. It opens a browser verification flow.
Nous Portal
Hermes labels this recommended. It is a separate Nous subscription covering many models and tools.
Run models locally
No account, but model download and Mac resource requirements make this a later/advanced choice.
Fireworks AI, MiniMax, Qwen Code, Anthropic API Key, or another API key
Choose only if you already use that provider and understand its access or billing requirements.
I’ll choose a provider later
You may defer, but Hermes cannot answer until model access is connected.
Step 03
Approve ChatGPT or Codex access
3D. ChatGPT/Codex: enter the device code
Current Hermes docs and source confirm that this option uses device-code authentication. You do not type your ChatGPT password into Hermes.
Select ChatGPT or Codex Subscription.
Hermes displays a temporary device code and opens an OpenAI verification page.
The browser or code window may open behind Hermes. Click your browser in the Dock or press Command–Tab to bring it forward.
Sign in to the correct OpenAI account if asked.
Enter the device code exactly as shown and approve access.
Return to Hermes Desktop and allow the connection to finish.
Keep the device code private while it is active. Do not email it, post it, or include it in a screenshot. Use only the OpenAI verification page opened by Hermes.
If the window is hidden
Click the browser in the Dock, press Command–Tab, inspect other browser tabs/windows, or use Mission Control.
If the code expires
Restart the sign-in and use only the newest code. Current Hermes source waits up to 15 minutes before timing out.
3E. Verify one useful chat
After the browser reports success, return to Hermes. The provider screen should complete and chat should become available. Then ask:
What can you help me do on this Mac? Give me three beginner-safe examples.
If Hermes answers clearly, installation and model access are working.
The installer does not need to interview you about your business, goals, workflows, tools, or agent roles. Those belong to later onboarding—not Mac installation.
Step 04
Run a health check only if needed
Most beginners should stay in the desktop app. Use Terminal only when the app, documentation, or support asks you to verify something.
Open Terminal from Applications → Utilities → Terminal. Then use these commands exactly:
Confirm Hermes command exists
hermes --version
Run health check
hermes doctor
If a command is not found, quit and reopen Terminal, then try again. If it still fails, return to the desktop app or support path.
Step 05
What to do next
After Hermes answers, give it one practical job instead of exploring every setting.
If you are a...
Start with this workflow
Solopreneur
Turn one messy idea into an offer outline, task list, and next three actions.
Small-business owner
Draft FAQ replies, missed-call follow-up text, review-request copy, or an intake checklist.
Creator
Create a content outline, research summary, or repurposing checklist.
Student / learner
Build a study plan, summarize a reading, or create a skill-building tracker.
SAGE9AI principle: first useful workflow beats perfect setup. Get one win, then stack skills and agents around that win.
Step 06
Beginner safety boundaries
Do not paste passwords, API keys, recovery codes, bank/tax data, health records, or private client records into test prompts.
Do not allow agents to send, buy, delete, file, publish, or message without human approval.
If you use a paid provider, check billing and usage settings before heavy experimentation.
Quick troubleshooting
Problem
First fix
macOS says the app cannot be opened.
Confirm the installer came from the official Hermes site, then check System Settings → Privacy & Security for an approval option.
The provider window or device code seems missing.
Check behind Hermes: click the browser in the Dock, press Command–Tab, inspect other browser windows/tabs, or use Mission Control.
The device code is expired or invalid.
Restart ChatGPT or Codex Subscription sign-in and use only the newest code.
Hermes opens but does not answer.
Check provider login/API key setup. If available, run hermes doctor from Terminal.
hermes is not found in Terminal.
Quit and reopen Terminal. If still missing, use the desktop app and return to command-line setup later.
The installer or Hermes says developer tools are missing.
Return to Step 3A, install Apple Command Line Tools, then reopen Hermes Desktop.
Checklist
Beginner success checklist
I downloaded Hermes Desktop from the official Hermes site.
I opened the Hermes Desktop app.
I selected or connected a model provider.
I received one clear Hermes answer.
I know not to paste sensitive data into random tools.
I know Terminal is a fallback, not the first path.
I picked one useful workflow to try next.
I know I can ask Hermes to help configure advanced features later.
Next SAGE9AI step:
Use the AI Agent Starter Kit to turn this working install into a first agent workflow, then expand into Skill Stacks, Agent Stacks, and Job Stacks.
Pro Tip:
Once your basic agent is up and running, it can install, configure, and set up anything else you would like within the agent harness. No need to guess or research how to do it, because your agent already knows. Just ask it. For safety, tell it to explain the plan before making changes, connecting accounts, or sending messages.
Source basis: prior Hermes Agent Mac Beginner Install Guide v1 plus the current Hermes documentation, which recommends the Hermes Desktop installer on macOS or Windows and keeps command-line installation as the non-desktop fallback.
