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, complete setup, then prove one useful chat before adding advanced tools.
What you installHermes Desktop, the local app experience for chatting with Hermes Agent on your Mac.
What Hermes needsA model provider so Hermes can answer. The simplest beginner route is the login/OAuth path if available.
What success meansYou 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
This is the detailed beginner install path. Start by making sure Apple’s developer tools are available, then download the official Hermes Desktop installer, answer the setup questions, connect a model provider, and confirm one working chat.
3A. Check Apple Command Line Tools / Xcode tools first
Hermes may need Apple’s Command Line Tools for Git and build support. Check before you install.
Open TerminalApplications → Utilities → Terminal, or press Command-Space and search “Terminal.”
Check for the toolsxcode-select -p
git --version
| If you see... | What it means | What to do |
|---|
/Library/Developer/CommandLineTools or another developer path | The tools are already present. | Continue to download Hermes Desktop. |
xcode-select: error or Git opens an installer prompt | The tools are missing. | Run the install command below and approve Apple’s dialog. |
xcode-select --install
When the Apple dialog appears, click Install, accept the license, and wait. It can take 10–30 minutes. When it finishes, rerun xcode-select -p and git --version.
Successful result after rerunning the checksxcode-select -p should print a developer-tools path, usually /Library/Developer/CommandLineTools. git --version should print a version line such as git version 2.39.5 or newer. The exact version number does not matter; a clean version line means Git is available.
3B. Download and open Hermes Desktop
- Open a browser and go to https://hermes-agent.nousresearch.com/.
- Click Download for macOS. The Mac download is the Hermes Desktop installer.
- Open the downloaded installer file from Downloads.
- If macOS warns that the app was downloaded from the internet, choose Open only if it came from the official Hermes/Nous Research site.
- If macOS blocks the app, open System Settings → Privacy & Security and approve the blocked app from there.
- Follow the installer screens and keep the default location unless you have a reason to change it.
3C. What Hermes Desktop setup may ask
The current Hermes docs say the desktop installer handles the app and command-line install, then first-time setup focuses on choosing how Hermes will connect to a model and which capabilities to enable. If a question appears, use this table.
| If Hermes asks... | What it means | Beginner answer |
|---|
| Recommended provider path | Hermes needs an AI account before it can answer. | Choose ChatGPT OAuth/OpenAI Codex or xAI Grok OAuth. These are the SAGE9AI recommended beginner paths because they use browser login instead of manual API-key setup. |
| ChatGPT OAuth / OpenAI Codex | Hermes signs in through your ChatGPT/OpenAI account and uses Codex models. | Choose this if you already use ChatGPT. Complete the browser login, then return to Hermes. |
| xAI Grok OAuth / SuperGrok | Hermes signs in through xAI/Grok with browser login and no API key. Hermes docs list this as “xAI Grok OAuth (SuperGrok / Premium+).” | Choose this if you have Grok/SuperGrok/Premium+ access. Complete the browser login, then return to Hermes. |
| Full Setup | Walks through providers, tools, and options yourself. | Use this if Hermes does not show the recommended OAuth choices on the first screen. |
| Blank Slate | Starts with only the minimum agent pieces enabled. | Skip for beginner installs. It is for users who want tight manual control. |
| Messaging gateway or platforms | Lets Hermes work through Telegram, Discord, Slack, WhatsApp, Signal, email, and similar channels. | Skip / Later unless this install is specifically for messaging access. |
Step 03
Finish setup inside Hermes Desktop
3D. Connect a model provider
Hermes needs a model provider. The provider is the AI brain Hermes calls when you chat.
| Choice | Good for | Beginner answer |
|---|
| ChatGPT OAuth / OpenAI Codex | Beginners who already use ChatGPT and want browser login instead of API keys. | Recommended. Sign in in the browser; return to Hermes after success. |
| xAI Grok OAuth / SuperGrok | Beginners who already use Grok/SuperGrok/Premium+ and want browser login instead of API keys. | Recommended. Choose the xAI Grok OAuth option, sign in in the browser, then return to Hermes. |
| OpenRouter or another API key | Trying many models/providers later. | Fallback only. Use if you already have an API key or are comfortable setting billing limits. |
| Local models | Privacy/cost experimentation after the first win. | Skip for first install unless you already know you want local inference. |
When in doubt, choose ChatGPT OAuth or Grok OAuth first. You can change providers later from Hermes.
3E. Answer the first-time setup questions
| If Hermes asks... | Beginner answer |
|---|
| Choose model/provider | Pick ChatGPT OAuth/OpenAI Codex or xAI Grok OAuth if available. Do not optimize model choice yet. |
| Allow tools / terminal / file access | Keep the normal/default safe settings. Do not enable approval-bypass or “YOLO” modes for a beginner install. |
| Enable memory or skills | Accept the default. These help Hermes remember preferences and reuse workflows. |
| Configure messaging platforms | Skip for now unless this install is specifically for Telegram/WhatsApp/Discord access. |
| Run setup wizard again later | Use hermes setup from Terminal or the app’s settings/configuration surface if you need to redo choices. |
3F. Verify one useful chat
Do not start customizing immediately. First prove that Hermes works.
Ask Hermes:
“What can you help me do on this Mac? Give me three beginner-safe examples.”
If Hermes answers clearly, your first install goal is complete.
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 existshermes --version
Run health checkhermes 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 setup/login flow is confusing. | Choose the simplest provider path available, or skip advanced provider choices and return after the first working chat. |
| 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. |
