The DADman software version 5.3.4 for DAD AX32, DX32 and Avid MTRX now adds macOS Mojave compatibility.
Make sure to also update your AX32 firmware to version 2.3.0.1, which gives you the ability to navigate your connected devices much faster and more easily by adding custom names to external MADI, Dante and SDI interfaces.
