M-audio Radium 49 Driver Mac May 2026
If you are running an older Mac (High Sierra, Mojave, or earlier), you can still use the final official drivers. Below is the official driver history for the Radium 49.
If you just need a basic keyboard to play software instruments (pianos, synths, drums) on your Mac, keep the Radium 49. Plug it in, ignore the driver error, and it will trigger notes just fine.
But if you bought the Radium 49 to use the faders and knobs for mixing or synth parameter control, you are out of luck on a modern Mac. No hack, workaround, or third-party utility can fully restore the advanced functionality that the missing 32-bit driver provided.
Recommendation: Use it as a simple MIDI keyboard or recycle it. For serious production, invest in a 2020+ controller.
Since the official driver is dead, you must use third-party software to re-map the Radium 49’s controls. The Radium sends proprietary SysEx (System Exclusive) messages for its faders and knobs. You need a tool to translate those into standard MIDI CC (Control Change) messages.
To summarize the search for the M-Audio Radium 49 driver for Mac:
Final Action Step: Plug your Radium 49 into your Mac right now. Open a piano VST. If you hear sound, you are done. No driver required. Enjoy your vintage piece of music technology.

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). Since the official driver is dead, you must
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.
Do you have a MIDI-to-USB interface on hand to try the 5-pin connection method?
The M-Audio Radium 49 is a legacy MIDI controller that presents significant compatibility challenges on modern Mac systems because it is not class-compliant and relies on drivers that are no longer officially supported for recent macOS versions. Compatibility Status
Modern macOS (Catalina 10.15 to Sequoia 15): There are no official drivers for these versions. M-Audio considers the Radium 49 an "end-of-life" product.
Legacy macOS (up to Yosemite 10.10): The last known stable drivers were released for OS X 10.8.5 Mountain Lion, though some users report success using them on 10.9 Mavericks and 10.10 Yosemite.
Classic Mac OS (9.0 - 9.2.2): Drivers are available for vintage systems using the MIDISPORT 3.0.8 installer. Working Around Driver Issues
If you are on a modern Mac and the device is not recognized, the most reliable "driverless" fix is to bypass the Radium’s internal USB interface entirely.
Use a MIDI-to-USB Cable: Connect a dedicated MIDI interface cable from the MIDI OUT port on the back of the Radium 49 to a USB port on your Mac. Since these cables are usually class-compliant, your Mac will recognize the MIDI signal without needing the original Radium drivers.
External Power: When using the MIDI OUT workaround, you may need an external 9V DC 500mA power supply, as the USB cable may not provide enough power to the keyboard in this configuration. Troubleshooting Tips for Older Macs
If you are on a compatible legacy OS (e.g., 10.10 or older):
M Audio Radium49 compatible with Catalina? Workaround? : r/ableton
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.
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.
By bypassing the Radium’s internal USB interface, you can make the keyboard "immortal" on modern systems: having trouble with a radium 49 key station
The M-Audio Radium 49 holds a special place in the history of home recording. Released in the early 2000s, it was one of the first affordable, semi-weighted 49-key controllers that offered programmable faders and a sleek blue aesthetic. For many producers, it was their first MIDI controller.
However, if you have dusted off an old Radium 49 or bought one second-hand and plugged it into a modern Mac, you have likely encountered the "M-Audio Radium 49 Driver Mac" headache. You plug it in, the lights turn on, but your Mac refuses to acknowledge its existence, or the keys work while the faders and knobs do nothing.
This long-form guide covers everything you need to know about getting this legacy hardware running on modern macOS systems, the difference between Class Compliant and Driver-dependent modes, and how to program the interface once it is connected.
| macOS Version | Official Driver Available | Functionality Level | Recommendation | |---------------|--------------------------|---------------------|------------------| | 10.5 – 10.13 (Leopard–High Sierra) | Yes (Radium49_OSX_2.2.2) | Full | Use legacy driver | | 10.14 (Mojave) | Partial (32-bit deprecation) | Limited | Not recommended | | 10.15 (Catalina) – 14.x (Sonoma) | No | Class-compliant only | Use third-party tools |
Note: Apple’s removal of 32-bit application support (Catalina) and kernel extension (kext) restrictions makes the original installer non-functional on newer Macs.
