Driver installation

On macOS High Sierra and Mojave, there are driver security systems in place to prevent the installation of malicious or unrecognized software/drivers to the system. When installing the drivers for the first time, you'll need to give them permission. If you are not prompted to allow them, you will need to manually open the System Preferences to Security & Privacy > General to allow the installation. This will only appear for 30 minutes after installation.

Driver reinstallation

if you did not see it or have troubles with your device driver not appearing, please reinstall the driver following these steps.

1. Disconnect the DDJ-RB.
2. Download the driver.
3. Open the driver package and run the uninstaller file.
4. Reboot your computer.
5. Open the driver package and run the driver installation file.
6. After the installation has completed, give the drivers permission if necessary (High Sierra and Mojave).
