# Installation

> Download and install Steno on macOS. The setup takes about five minutes, most of which is downloading the local AI models.

## Requirements

* macOS 12 (Monterey) or later
* 8GB RAM minimum (16GB recommended for larger models)
* \~5GB free disk space for the default models

## Install Steno

<Steps>
  <Step title="Download the DMG">
    Go to [stenoai.co](https://stenoai.co) and click **Download**. Choose the right build for your Mac:

    * **Apple Silicon** (M1, M2, M3, M4) -- use the `arm64` build
    * **Intel** -- use the `x64` build

    If you are unsure, go to **Apple menu → About This Mac** and look for "Apple M" in the chip name.
  </Step>

  <Step title="Open the DMG and drag to Applications">
    Open the downloaded `.dmg` file. Drag the Steno icon into your Applications folder.
  </Step>

  <Step title="Launch Steno">
    Open Steno from Applications. macOS may show a security prompt on first launch -- click **Open** to proceed. This prompt appears because Steno is distributed outside the Mac App Store.

    If macOS blocks the app entirely, go to **System Settings → Privacy & Security** and click **Open Anyway** next to the Steno entry.
  </Step>

  <Step title="Download models">
    On first launch, Steno will prompt you to download the default models:

    * Transcription: `whisper-small` (\~480MB)
    * Summarization: `llama3.2:3b` (\~2GB)

    Both downloads happen inside the app. This requires an internet connection and takes a few minutes depending on your connection. After this, Steno runs entirely offline.
  </Step>

  <Step title="Grant microphone access">
    When you start your first recording, macOS will prompt for microphone permission. Click **Allow**. To record system audio (both sides of a call), follow the [system audio setup](/features/recording) guide.
  </Step>
</Steps>

## Verify the installation

Once setup is complete, go to **Settings → Setup Check** inside the app. This runs a diagnostic that confirms:

* Whisper model is installed and functional
* Ollama is running and the summarization model is loaded
* Storage paths are writable

If any check fails, the setup screen will show the specific error and how to resolve it.

## Updates

Steno updates automatically in the background. When an update is ready, you will see an **Update available** notice in the app. Updates install on the next quit -- you do not need to re-download a DMG manually.
