# macOS

### Installing Requirements

The Haptic Jacket Controller software requires Node.js and Python 3. Download them if not present in the system.

* Node.js (<https://nodejs.org/en/>)
* Python 3 (<https://www.python.org/download/releases/3.0/>)

### Downloading Software and Running

Download the compressed macOS application from here: <https://drive.google.com/file/d/1kvrpT0f_PRYW8ZTPdl0S-cqlqU7Hey2I/view?usp=sharing>

Extract the zip file.

The application is now ready to run.

{% hint style="info" %}
The macOS application was built on macOS Big Sur version 11.1. Might be incompatible with earlier versions.
{% endhint %}

{% hint style="warning" %}
If it says the application *cannot be opened because the developer cannot be verified,* Go to `System Preferences -> Security & Privacy` and click *Open Anyway.*
{% endhint %}

Once everything runs well, the screen should look like this.&#x20;

For information on how to use the Simulator, please refer to [**User Guide**](/haptic-jacket/using-the-application/untitled.md).

### Accessing Python API on macOS

The haptic jacket simulator can be controlled by a python API.&#x20;

The API Files are already included in the zip file previously downloaded.

To test the API, run the Haptic Jacket Controller, then run the following commands separately in the terminal, **while running the Application at the same time**.

```
cd Desktop/Haptic-Jacket-API-Python-main
python3 api_test.py
```

{% hint style="warning" %}
Before running the API, make sure that the modules have been scanned and placed on the jacket.
{% endhint %}

Make changes to the file `api_test.py` to see different outputs in the simulator.

Refer to the [**API Documentation**](/haptic-jacket/api-documentation/untitled.md) for detailed usage of API.
