Because macOS no longer trusts kexts (kernel extensions) from 2012, you must:
The M-Audio X-Session Pro was designed for the era of macOS Tiger and Leopard (OS X 10.4/10.5). As Apple evolved its operating system architecture, particularly with the shift to 64-bit kernels and the introduction of macOS Catalina (and now Apple Silicon), the old Kernel Extensions (kexts) that powered the X-Session Pro were deprecated.
If you search the M-Audio (now inMusic) website, you will likely find that the X-Session Pro is listed as "Legacy" or "Discontinued," with the final supported OS often cited as macOS 10.13 (High Sierra) or earlier. There are no official drivers for macOS Big Sur, Monterey, Ventura, or Sonoma.
So, is the hardware dead? Not necessarily.
The M-Audio X-Session Pro is a class-compliant USB MIDI controller, meaning it does not require specific drivers to operate on modern macOS versions. Because it uses standard Core MIDI protocols, it is plug-and-play across a wide range of systems. Quick Setup Guide for Mac

If your controller isn't responding in your DJ software, follow these steps to confirm your Mac sees it: X-Session Pro Quick Start Guide
The M-Audio X-Session Pro is a vintage MIDI DJ controller that remains popular due to its tactile layout, but finding a modern "hot" driver for Mac can be tricky because the device is actually class-compliant. This means it was designed to work natively with macOS without needing a dedicated driver installation for standard MIDI functionality. Essential Setup for Modern macOS
Because it is class-compliant, your Mac should recognize the X-Session Pro as soon as you plug it in via USB. If you are experiencing issues on newer versions like macOS Sonoma or Sequoia, follow these steps to confirm connectivity:
Check MIDI Studio: Open Audio MIDI Setup (located in /Applications/Utilities) and select Window > Show MIDI Studio. Your device should appear as a solid icon; if it is grayed out, your Mac is not seeing the hardware connection.
System Report Verification: Click the Apple Menu > About This Mac > System Report, then select USB from the left sidebar. Look for "X-Session Pro" in the USB device tree to ensure the hardware is receiving power and communicating with the bus.
Security Permissions: On Apple Silicon (M1/M2/M3) Macs, you may need to manually "Allow" the connection in System Settings > Privacy & Security if a prompt appears regarding a blocked USB accessory. Troubleshooting "Legacy" Issues
While the hardware itself is class-compliant, the original Enigma software (used for custom MIDI mapping) is outdated and not supported on modern 64-bit macOS versions.
Native Mapping: Instead of searching for an Enigma "driver," use the native MIDI mapping features in modern DJ software like Ableton Live, Traktor Pro, or djay Pro.
Hardware Conflicts: If the device isn't showing up, try using a different USB cable or a powered USB hub, as older devices sometimes struggle with the lower power output of modern USB-C ports.
Legacy Drivers: For very old macOS versions (10.4 or 10.5), you can still find archival files on the M-Audio Support Downloads page by selecting "Legacy" from the series list. X-Session Pro Quick Start Guide
The M-Audio X-Session Pro is a classic DJ-style MIDI controller, but getting it to work on modern macOS systems like Sonoma, Ventura, or Monterey can be confusing because it doesn’t follow the typical "download and install" driver path. The Truth About the M-Audio X-Session Pro Driver for Mac Because macOS no longer trusts kexts (kernel extensions)
The most important thing to know is that the M-Audio X-Session Pro is class-compliant on Mac. According to the M-Audio X-Session Pro Quick Start Guide, it requires no additional drivers to function on Mac OS X or newer.
Because it uses Apple’s native Core MIDI drivers, it is "plug-and-play." If you are searching for a specific driver file to download for a modern Mac, you won't find one because it isn't necessary. How to Connect and Verify Your Controller
Since there is no driver to install, you simply need to ensure your Mac recognizes the hardware. Follow these steps:
Direct Connection: Plug the X-Session Pro into a USB port. If you are using a modern MacBook with USB-C ports, use a high-quality USB-C to USB-B cable or a powered hub to ensure the device receives enough power.
Audio MIDI Setup: Open Audio MIDI Setup (found in Applications > Utilities).
Show MIDI Studio: Go to Window > Show MIDI Studio. You should see an icon for the "X-Session Pro." If it is highlighted, your Mac sees the device.
Test Connectivity: Click the Test Setup icon (the keyboard icon) in the MIDI Studio toolbar. When you move a fader or knob on the X-Session Pro, you should hear a "ding" or see the icon blink, confirming the Mac is receiving data.
Troubleshooting Compatibility on Modern macOS (Sonoma/Ventura/Sequoia)
While the hardware is class-compliant, the software you use must also be compatible with your current macOS version.
Apple Silicon (M1/M2/M3) Support: Most class-compliant MIDI devices work flawlessly on Apple Silicon. However, M-Audio's Compatibility Page regularly updates status for the latest OS versions like macOS 15 Sequoia.
Manual Mapping: In modern DJ software like Serato DJ, Traktor Pro, or Ableton Live, the X-Session Pro may not have a built-in "template." You will likely need to use the MIDI Learn function within your software to manually assign the knobs and crossfader to the on-screen controls.
Legacy Software: Older software that originally came with the unit, such as Torq LE or Enigma, is 32-bit and will not run on any macOS version from Catalina (10.15) onwards. Where to Find Support
If your device isn't appearing in MIDI Studio, you can check the M-Audio Legacy Support section for any old documentation, though keep in mind that official technical support for this legacy product has largely concluded.
If your Mac isn't recognizing the X-Session Pro, it is likely because of a "ghost" legacy driver interfering with the system's native MIDI handling.
Remove Old Drivers: Open Finder and navigate to /Library/Extensions/. Look for any files starting with M-Audio (e.g., M-AudioXSessionPro.kext) and move them to the Trash.
Restart: Reboot your Mac. Once restarted, the system will use its built-in Core Audio/MIDI drivers to identify the device automatically. 2. Verify in Audio MIDI Setup
Because there is no dedicated software dashboard, use the macOS native utility to check connectivity: Open Audio MIDI Setup (found in /Applications/Utilities/). Go to Window > Show MIDI Studio. If the user means the device is “hot”
If the X-Session Pro icon is grayed out, try unplugging and re-plugging the USB cable. If it appears bright, your Mac "sees" the hardware. 3. Connection & Power Tips
Modern Macs (especially Apple Silicon M1/M2/M3) can be finicky with older USB 1.1/2.0 hardware.
Avoid Hot-Swapping: It is a best practice to connect the X-Session Pro before launching your DAW (like Ableton or Logic) to ensure the MIDI handshake is successful.
USB Hubs: If you are using a USB-C Mac, try a high-quality powered USB hub. Sometimes the low power draw of the X-Session Pro isn't properly triggered by direct USB-C to USB-B adapters. 4. Legacy Downloads
If you are running an older "vintage" Mac (macOS 10.14 Mojave or earlier) and specifically need the original installer for legacy software support, you can still find them on the M-Audio Legacy Support Page by selecting "Legacy" from the series menu. If you'd like, I can help you:
