A driver for MCX8000 support was previously required on macOS Catalina. This driver is no longer necessary on macOS Big Sur or macOS Monterey and may even prevent communication altogether. We recommend that users uninstall this driver before using the MCX8000 with macOS Monterey.
To uninstall, please download the MCX8000 Mac Driver at denondj.com/downloads. Once downloaded, double-click the .dmg and run the MCX8000 MIDI Uninstaller.
