M-audio Radium 49 Driver Mac
Apps like MIDI Pipe or Controller Mate can sometimes sniff the raw data from the knobs (which send CC messages, just via a different protocol the Mac doesn't parse automatically). However, success is limited and requires heavy technical tinkering.
| User Profile | Recommended Action | |--------------|--------------------| | Need only basic keyboard playing (notes, pitch, mod) | Use native macOS driver – works fine | | Need knobs/sliders for studio use | Use DAW MIDI Learn + manual mapping | | Need full original functionality (buttons, presets, editor) | Use a legacy macOS system (10.13 High Sierra) or a Windows PC | | Running macOS 15+ (Sequoia) | No change; class-compliant only – same as Sonoma |
Final Verdict: The M-Audio Radium 49 is not officially supported on modern macOS, but remains usable as a basic MIDI controller. For professional or critical use requiring all 49 keys + full controller features, consider replacing it with a modern, class-compliant controller (e.g., M-Audio Oxygen Pro, Arturia KeyLab, Novation Launchkey).

If you are using a modern Mac (Intel or Apple Silicon), you have two primary options to keep the hardware running: 1. The MIDI-to-USB Hardware Fix (Recommended)
The most reliable way to use a Radium 49 today is to bypass its internal USB interface entirely:
Connect a standard 5-pin MIDI cable from the MIDI OUT port on the back of the Radium 49.
Plug that cable into a modern, class-compliant MIDI interface (like the M-Audio MIDISPORT or a simple MIDI-to-USB adapter).
Use the Radium’s USB port only for power, or use a 9V DC power adapter. 2. Open-Source Driver (Technical)
There is a community-maintained project on GitHub and SourceForge that provides a 64-bit driver for legacy M-Audio devices.
Compatibility: Reported to work on macOS 10.14 (Mojave) and newer. Report compiled based on M-Audio legacy driver archives,
Warning: Installation can be complex and may require disabling System Integrity Protection (SIP) or using Xcode to compile/install. 🔍 How to Check Connection
To see if your Mac even "sees" the device, use the built-in Audio MIDI Setup: having trouble with a radium 49 key station
The Radium 49 is an older device that draws a significant amount of power from the USB bus. Modern Macs, especially MacBooks with low-power USB-C ports, may throw an error saying "USB Device Disabled - Too much power."
Solution: You must use a Powered USB Hub. This is a hub that plugs into a wall outlet. The hub provides the power to the Radium 49, rather than the computer doing the heavy lifting. This resolves 90% of connection issues with vintage USB gear.
Given the driver situation, is the M-Audio Radium 49 worth keeping on a modern Mac?
If you are on a modern Mac (Intel or Apple Silicon), here is the hard truth that will save you hours of searching the internet:
There is no official driver that will fully support the programmable features of the Radium 49 on these operating systems.
M-Audio has marked the Radium 49 as "Legacy" and "Discontinued." The final driver released for this unit was intended for much older OS versions (macOS High Sierra and earlier).
Does that mean it is useless? Not necessarily. Many users report that the basic keyboard functions may work via Mac’s generic Core MIDI driver.
Before you frantically search for a downloadable file, you must understand a fundamental shift in how macOS handles audio devices.
