An alternative hardware solution is to place a modern MIDI interface in between the Radium 49 and your computer. Devices like the iConnectivity mio series or the Roland UM‑ONE can receive the Radium’s 5‑pin MIDI output and present it as a class‑compliant USB MIDI device to the Mac. This is essentially the same concept as using a generic USB‑to‑MIDI adapter, but with the added benefit of low latency and professional‑grade reliability.

However, using this classic controller with a modern Mac can be challenging. The Radium 49 was never a class‑compliant MIDI device—it requires proprietary drivers to communicate via USB. The official drivers provided by M‑Audio were written for Mac OS X 10.4 (Tiger), and they have never been updated for 64‑bit versions of macOS. As a result, older driver installation packages will be refused by modern versions of macOS, and the keyboard will appear invisible to your music production software. This issue often leads to a frustrating “Radium 49 not working” scenario after a macOS upgrade. Visit the official legacy archive page

The M-Audio Radium 49 is a popular MIDI keyboard controller designed for music production and performance. Released in 2006, it features 49 full-size, velocity-sensitive keys, 16 backlit MPC-style pads, and a variety of controls for navigating and manipulating virtual instruments and effects. If you're a Mac user who owns a Radium 49, you'll need to install the correct drivers to ensure seamless communication between the keyboard and your computer. In this article, we'll provide a detailed guide on how to install and configure the M-Audio Radium 49 driver on a Mac.

Keep an old MacBook running macOS 10.13 High Sierra or 10.14 Mojave. This is the last OS that can run the 32-bit M-Audio driver. This is impractical for daily production.

Plug the USB end of the interface into your Mac (or USB hub). Because these interfaces are class-compliant, your Mac will recognize the interface instantly.

Version 3.5.3 was the last major update released by M-Audio.
