# Launch Discovery Server using Command Line for MacOS

## On Mac

1. You will first need to insure that you have installed the [NDI SDK](https://docs.ndi.video/all/developing-with-ndi/sdk). 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.
