 Update Instructions

Mac

1. Ensure your SSL hardware device is powered on and connected to your computer via a USB cable. SSL 2/2+ users - please note - connecting using a USB-C to USB-C cable may not work and the update may fail. To guarantee a successful firmware update, please use a USB-A to USB-C cable. If your Mac only has USB C sockets, then a USB Hub that has a USB A connection will be needed – something like this.
2. Download the SSLAudioFirmwareUpdater.zip package.
3. Within the package locate and unzip the macOS.zip. Unzip it and launch the SslAudioFirmwareUpdater application found inside.
4. The SSL device will automatically be detected and display its current firmware version in the application. If you have multiple SSL devices connected, select which one you want to update using the drop-down menu in the application.
5. Select Update Device. The device will begin the update process.
6. A ‘Device Firmware update complete’ message will appear. You can now close the window. Should the firmware update fail of be interrupted while in progress, power off the SSL device, relaunch the updater application then power on the console once more to re-attempt.
