, meaning it requires specific vendor drivers to function over USB on a Mac. Because M-Audio has discontinued support for this model, finding working drivers for modern macOS versions (macOS 10.15 Catalina and later) is difficult, as the last official drivers were designed for much older systems. Driver Compatibility & Workarounds

If you are using a modern Mac (Intel or Apple Silicon), official USB support is likely unavailable. You can try the following options based on your system version: For Legacy macOS (e.g., 10.10 Yosemite or 10.9 Mavericks): Some users found success using the v3.5.3 USB MIDI driver Apple Community or the legacy M-Audio Support The Hardware Workaround (Recommended for Modern Macs): Instead of USB, use a standard 5-pin MIDI-to-USB interface cable (available from retailers like Sweetwater

The M-Audio Radium 49 is a legacy controller that is not class-compliant, meaning it requires specific drivers to function over a USB connection. Because M-Audio has not released updated drivers for modern macOS versions, getting it to work depends entirely on which version of macOS you are running. 1. Identify Your macOS Version

Legacy macOS (10.10 Yosemite or earlier): You can likely use the original M-Audio USB MIDI Driver v3.5.3.

Modern macOS (10.11 El Capitan to macOS 15 Sequoia): No official drivers exist. The USB port on the keyboard will likely only provide power, not data. 2. The Universal "No-Driver" Workaround

If you are on a modern Mac (Intel or Apple Silicon), the most reliable way to use this keyboard is to bypass its internal USB interface entirely.

Purchase a Class-Compliant MIDI-to-USB Interface: Look for a cable or interface that has 5-pin MIDI DIN connectors on one end and USB on the other (e.g., the iConnectivity mio or a similar interface known to work with macOS 13+). Connections:

Connect the MIDI OUT of the Radium 49 to the MIDI IN of your new interface. Connect the USB end of the interface to your Mac. m-audio radium 49 driver mac

Power: The Radium 49 still needs power. You can either plug its original USB cable into a USB wall charger or use a 9V DC 500mA power adapter. 3. Verify Connection in macOS

Once connected via an interface, follow these steps to ensure your Mac sees the device: Open Audio MIDI Setup (found in Applications > Utilities). Go to Window > Show MIDI Studio.

Your interface (not the Radium 49 itself) should appear as a solid icon. If it is greyed out, check your cable connections.

Click the Test MIDI Setup (keyboard icon) and press a key on the Radium; you should see a blue light flash in the MIDI Studio window, confirming data is being received. 4. Community "Legacy" Fixes (For macOS 10.9–10.14)

Some users have had success using old drivers on slightly newer (but still legacy) Intel Macs by following these steps:

Connect the Radium 49 through a powered USB 2.0 hub rather than directly into a USB 3.0 or USB-C port.

In Audio MIDI Setup, manually create a "New External Device," name it "Radium 49," and check the "General MIDI" box. Install the v3.5.3 driver and restart your Mac. M Audio Radium49 compatible with Catalina? Workaround?

M-Audio Radium 49 is a legacy "end-of-life" product that is no longer officially supported

on modern macOS versions. Because it is "pre-class compliant," it requires specific drivers that were last officially updated for Mac OS X 10.8.5 (Mountain Lion) Driver Compatibility & Workarounds

If you are on a modern Mac (macOS Catalina 10.15 or newer, including Sonoma/Ventura), the official USB drivers will not work. Here are your options: Use a MIDI-to-USB Interface (Recommended)

: This is the most reliable workaround. Instead of using the Radium’s built-in USB port, connect a standard MIDI DIN-to-USB cable from the Radium's

Step 2: Verify in Audio MIDI Setup

Steps to Install on Legacy Macs:

  1. Download: Search the M-Audio support knowledge base for "Radium 49 Drivers" and select your older OS version.
  2. Security Settings: Before installing, go to System Preferences > Security & Privacy. You may need to allow apps downloaded from "Anywhere" or be prepared to override Gatekeeper warnings during installation, as these drivers are unsigned by modern Apple standards.
  3. Install: Run the installer. It usually requires a restart.
  4. Configure: Once restarted, open Audio MIDI Setup. You should see the Radium 49 listed. If it works, the icon will be solid black (not grayed out).

Part 1: The Driver Reality Check – No Official Support

Let’s address the elephant in the room immediately. There is no official M-Audio Radium 49 driver for macOS Catalina (10.15) or newer.

The last official drivers released by M-Audio (now owned by inMusic) supported macOS 10.13 High Sierra and 10.14 Mojave. These were 32-bit and 64-bit hybrid drivers designed for Intel-based Macs.

When Apple dropped 32-bit application support with Catalina and introduced stricter security protocols (notarization requirements), the legacy Radium drivers ceased to function. Installing them on macOS Ventura or Sonoma will result in installation failures, kernel extension blocking errors, or the system simply not recognizing the device in Audio MIDI Setup.

6. Conclusion & Recommendations

| 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).
