# Launch Discovery Server using Command Line for MacOS

## On Mac

1. You will first need to insure that you have installed the [NDI SDK](/all/developing-with-ndi/sdk.md). By default it will install to Library
2. If you did not change the install location, open [Terminal ](https://support.apple.com/guide/terminal/welcome/mac)on MacOS and enter the following command: 

```
open -a "Terminal" "/Library/NDI SDK for Apple/bin/Application.Mac.NDI.DirectoryService"
```

3. A separate Terminal window will open with NDI Discovery Service running. If a different directory was chosen to install the NDI SDK to, replace 'Library' with your chosen directory path.

3. On the NDI Sender, open [Access Manager](/all/using-ndi/ndi-tools/ndi-tools-for-windows/access-manager.md), and enter the IP address of your Mac and the **Port Number**

{% hint style="info" %}
If you choose not to use Access Manager you can still enter the IP address using the settings in the relevant section of the NDI device
{% endhint %}
