Just Play Lite NDI · 2026 documentation

Software Installation - Initial and Update (v.2026.x)

We assume that the operating system is configured properly and that you have been configuring all machines using the Requirements we have listed in the previous chapters.

The installation provides a fully functional demo of our playout applications and the final output will display a watermark. You have to acquire a license to disable the watermark. Please → contact us directly.

macOS Gatekeeper/Security & Privacy

Before the installation can start, it may be necessary to disable Apple's macOS Gatekeeper temporarily.  When opening one of the playout applications for the first time, it will be verified by the operating system, so please verify that depending on your macOS system version, either the “App Store and identified developers” or “App Store & Known Developers” option is selected.

Installation

Refer to Getting Started for the installation process.

We do not recommend to run the Composition Builder application (our real-time graphics template creation tool) and Just Play Lite NDI on the same machine at the same time and to use Composition Builder on another available Mac if possible. Running Composition Builder and Just Play Lite NDI at the same time on the same Mac may terminate a running playout!

Installing a new Version over an existing Version

Basically, a new installation and updating an older version works the same. But there are a few things you maybe would like to keep in mind when updating to a new version.

1. Preparations

  1. Make a backup of the current installation. The best would be a full backup of the startup disk to another disk. Otherwise, copy the Channel folder which can be found at “/Users/YourUserName/Library/Containers/Just Play Lite NDI/Data/Library/Application Support/ToolsOnAir/Just Play Lite NDI” to another storage device.

  2. Make sure you have a valid activation code for the new version. Please → contact us if you do not have a valid activation code.

  3. Download the new playout software version and all other updates you may need during the installation.

2. Stop the Current Playout

  1. Quit the Just Play Lite NDI playout applications.

Quitting Just Play Lite NDI will stop the current playout.

3. Update the Operating System

  1. Check which OS version is recommended for the new playout software version from the installer. With version 2026.x we support macOS Sequoia and macOS Tahoe (recommended), which you can download from Apple's App Store.

  2. On macOS Sequoia (15.4.x), go to the “Apple” menu, select “System Settings”, and click on “General → Software Update”.

  3. Make sure to install all available updates for your software until there are no updates left.

  4. Restart the Mac if you haven’t done so as part of the macOS update.

4. Update the ToolsOnAir Software Versions

  1. Extract the downloaded Playout Software and open the disk image (.dmg).

  2. Drag and drop the Just Play Lite NDI app onto the Applications folder, as described above.

  3. While copying, click on “Replace” if you get a warning that a folder already exists.

5. Activate the New Version

  1. Once the new version has finished copying, start Just Play Lite NDI.

  2. Follow the instructions in Chapter Activate/De-Activate the Channel  to activate the new version.

6. Start the Playout

  1. Start the Just Play Lite NDI application.

  2. In case you are asked to update the System, agree to do so.
