M-Audio-Firewire

Install M-Audio Kernel Extension (Driver)

OS X 10.10.x Yosemite

OS X 10.11.x El Capitan

---

This allows the installation of unsigned kernel extensions.

IT OPENS UP SEVERAL SECURITY VULNERABILITIES!

Proceed if you are ok with that.

Disable System Integrity Protection - Skip this step for OS X 10.10 Yosemite

1. Boot up in Recovery Mode (CMD-R while turning on the Mac)
2. Open Terminal
3. Enter the following command...
   • csrutil disable
4. Reboot

---

Enable Developer Mode for Kernel Extensions

1. Open Terminal
2. Enter the following…
   • sudo nvram boot-args=kext-dev-mode=1
3. Copy M-AudioFireWireBeBoB.kext to /System/Library/Extensions/
4. Enter the following commands...
   • cd /System/Library/Extensions/
   • sudo chmod -R 755 M-AudioFireWireBeBoB.kext
   • sudo chown -R root:wheel M-AudioFireWireBeBoB.kext
5. Reboot (or see optional next section first)

---

Optionally Install Additional Packages

1. Run each package (except M-Audio FireWire Kernel Extension.pkg) from the “Extracted installer Packages” folder.
2. Reboot

This portion is not required for the Firewire kext to work and show up in your audio applications.

You can resecure your computer but it will disable the M-Audio extension as it is unsigned. Here’s how...

1. Open Terminal
2. Enter the following command
   • sudo nvram -d boot-args
3. Reboot in Recovery Mode (CMD-R while turning on the Mac)
4. Open Terminal
5. Enter the following command...
   • csrutil enable
6. Reboot
