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.
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?
Getting your M-Audio Radium 49 running on a modern Mac can be a challenge because the keyboard is a "legacy" product that hasn't received official driver updates in years. While it was a staple of early 2000s home studios, its reliance on specific USB drivers makes it difficult to use on recent macOS versions like Ventura, Sonoma, or Sequoia.
Here is everything you need to know about M-Audio Radium 49 drivers for Mac, from official legacy support to modern workarounds. Official Driver Compatibility (Legacy Systems)
The Radium 49 is not "class-compliant," meaning it requires a specific driver to communicate via USB. Official support effectively ended after OS X 10.8 Mountain Lion.
Latest Official Driver: Version 3.5.3 was the last major update released by M-Audio.
Known Working Versions: This driver is confirmed to work on OS X 10.8 through 10.10 Yosemite for some users. m-audio radium 49 driver mac
Unsupported Systems: Any macOS from 10.11 El Capitan through the latest macOS 15 Sequoia is not officially supported. The Best Workaround: Using a MIDI-to-USB Interface
If you are on a modern Mac (Intel or Apple Silicon), the built-in USB port on the Radium 49 likely won't work because the driver won't load. However, the Radium 49 has a standard 5-pin MIDI Out port on the back.

Getting Your M-Audio Radium 49 Working on Modern macOS If you’ve recently rediscovered an M-Audio Radium 49 in your closet or picked one up second-hand, you probably noticed a frustrating reality: M-Audio stopped officially supporting this keyboard years ago.
Finding an "official" M-Audio Radium 49 driver for modern macOS versions (like Monterey, Ventura, or Sonoma) is technically impossible because they don't exist. However, because the Radium 49 was designed during a transitional era of MIDI technology, you aren't completely out of luck. The Problem: Legacy Architecture
The M-Audio Radium 49 was released when Macs used PowerPC processors and early Intel chips. The last official drivers were written for OS X 10.5.8 and 10.6.8. Modern macOS requires 64-bit class-compliant drivers, which the Radium 49 lacks in its native USB mode. Solution 1: Use the MIDI Out Port (Recommended)
The most reliable way to use a Radium 49 today is to bypass the USB connection entirely.
Since the Radium 49 has a standard 5-pin MIDI Out port on the back, it can send MIDI data to any modern system if you use a USB MIDI Interface. Plug a MIDI cable into the MIDI Out of the Radium 49.
Plug the other end into the MIDI In of a class-compliant USB MIDI interface (like an iConnectivity mio or a Roland UM-ONE). Plug the interface into your Mac.
Power the Radium 49 using a 9V DC power adapter (since it won't be getting power from the USB bus).
Your Mac will "see" the interface, which is class-compliant, and the Radium 49 will work perfectly with Logic, Ableton, or GarageBand. Solution 2: The "Midiman" Legacy Driver Hack
Some users on forums have had success using the old "Midiman" or "M-Audio USB MIDI" drivers on older Intel-based Macs (macOS High Sierra or Mojave) by disabling System Integrity Protection (SIP).
Warning: This is not recommended for newer M1, M2, or M3 (Apple Silicon) Macs, as the driver architecture is fundamentally different and can cause system instability. Solution 3: Check for "Class Compliancy"
While the Radium 49 is notoriously not class-compliant, some later "Silver" versions of M-Audio's 49-key controllers were. Plug the USB cable into your Mac. Go to Applications > Utilities > Audio MIDI Setup. Open the MIDI Studio window (Window > Show MIDI Studio).
If a "USB MIDI Device" icon appears without you installing any software, you have a later model that is plug-and-play. Summary: Is it worth it?
If you have a cheap MIDI-to-USB interface and a power supply lying around, the Radium 49 is a great, lightweight controller with plenty of faders. However, if you have to buy all those accessories new, you might find that a modern, class-compliant controller like the M-Audio Oxygen 49 MKV is a better investment for your workflow.

today is to ignore its built-in USB port for data. Connect a standard MIDI cable from the Radium's MIDI Out to a modern, class-compliant MIDI-to-USB interface (like the iConnectivity mio or Roland UM-ONE). You may still need to plug the Radium into a wall outlet or a USB power brick for power.
Third-Party Drivers: Some users have had success using community-developed drivers (such as those found on GitHub) or by manually installing older Midisport drivers, though this is technical and potentially unstable. Performance Review

Here is the complete guide to setting up your M-Audio Radium 49 on macOS.
The Short Answer: You do not need to download a driver for modern macOS versions (macOS 10.11 El Capitan and later). The M-Audio Radium 49 is a "class-compliant" device, meaning it is plug-and-play.
However, if you are on an older version of macOS or need the advanced control panel software, follow the steps below.
To understand why the Radium 49 is difficult to use on a modern Mac, we have to look at how technology has shifted.
When the Radium 49 was released, USB was still maturing. To function efficiently, the device relied on proprietary drivers written by M-Audio (then Midiman). These drivers told the computer exactly how to interpret the data coming from the specific faders and knobs on the unit.
Fast forward to today, and Apple has aggressively pushed for "Class Compliant" devices. A Class Compliant device uses standard drivers built into the OS (Core MIDI on Mac) so that you can plug and play without installing anything.
The M-Audio Radium 49 is a hybrid device, but it is largely dependent on legacy drivers that are no longer supported by M-Audio or fully compatible with modern macOS architecture (Apple Silicon M1/M2/M3 chips).
The M-Audio Radium 49 is a legacy USB MIDI controller released in the mid-2000s. Official driver support from M-Audio (inMusic) ceased after macOS 10.14 Mojave. For modern macOS versions (10.15 Catalina through macOS 14 Sonoma and later), the device can only function as a class-compliant MIDI controller without access to advanced features (assignable buttons/faders) unless third-party workarounds are applied.
Note: M-Audio no longer hosts these files on their primary website as of 2022. However, they are available via the official M-Audio legacy driver archives and reputable driver databases. Always scan downloaded files for malware.
Driver Name: M-Audio USB MIDI Driver 6.1.3 (for macOS 10.4 - 10.14)
Alternative Download Source:
If you cannot find the driver on M-Audio’s site (navigate to Support > Legacy Products > Radium Series), you can check the Internet Archive (Wayback Machine) for m-audio.com snapshots from 2015-2018.
If you do get the driver working (or if you are using it generically and want to try mapping manually), understanding the Radium's programming is key. Unlike modern controllers that have simple "MIDI Learn" buttons, the Radium 49 requires you to program the messages into the unit itself using the hardware buttons.
