MEDIA WALL is downloadable media playback software for Mac. Before purchasing, please read the system requirements, demo restrictions, license conditions and refund information below.
System requirements and internet access
- Supported environment: A Mac with Apple Silicon; macOS 13 or later is recommended. Intel-based Macs have not been tested on physical hardware and are outside the scope of support. Windows, Chromebooks, smartphones and other platforms are not supported.
- External control: Control from show systems or remote-control systems is not supported. MIDI, OSC, NDI and DMX are not supported; support is under consideration for the future.
- Activation and offline use: Initial activation of your purchase requires an internet connection. The device certificate is valid for 30 days and renews when the app launches online. You can use the app offline while that certificate remains valid. These 30 days are not the expiry of your purchased entitlement.
- Loading times and playback performance vary depending on media format, resolution, duration, storage location and connected equipment.
Test the demo before purchasing
- Before purchasing, test the app with the Mac, media, external display and audio equipment you will actually use.
- The demo is available for 30 days from first use, for up to 30 minutes per launch.
- Demo restrictions include a watermark on PGM output, an audio announcement every 30 seconds during playback, and disabled project saving.
- For events or professional use, run a full rehearsal before the show and keep backups of the media you need.
- You are responsible for keeping your media and project backups and checking your setup. Responsibility for data loss, device problems, disputes with third parties and other losses is governed by applicable law and the Terms / License. Nothing in this notice excludes or limits liability that cannot legally be excluded or limited, or restricts your statutory rights.
macOS warnings or problems opening the app
- Use files obtained from the official distribution source.
- If a warning appears, check its wording and the source of the file. Do not assume that every warning is a false positive or disable security protections across your system.
- If you cannot open the app, contact support with the exact warning, app version and macOS version. Also see Apple’s guidance: Safely open apps on your Mac (opens in a new tab).
License conditions and prohibited use
- Commercial use and use for client or commissioned work are permitted.
- Each license permits registration of one Mac.
- For an individual purchase, the purchaser may use the registered Mac. For a company purchase, employees and contractors under the company’s management may use that registered Mac.
- The same purchaser may move the license to a replacement Mac. Release the old Mac registration before activating the new Mac. See the purchase & license guide for the steps.
- Reselling, lending or transferring the license to another person or company is prohibited as a general rule.
- Unauthorized redistribution or sharing of the software or license keys, unauthorized copying, bypassing activation, and simultaneous use on multiple Macs under one license are prohibited.
- Unauthorized modification or reverse engineering of the program is prohibited, except where permitted by applicable law.
Support and updates

- Support covers receiving your license key, installation, activation and moving to another Mac, and reproducible defects.
- Support does not include operating your show, setting up event equipment on your behalf, immediate assistance during a live show, or general training in third-party software or Mac operation.
