'요세미티'로 업그레이드 한 후 Profire2626 인식이 안될 때

If you’re using OSX Yosemite and are using professional audio sound card, you’ve no undoubtely discovered that the device will not work and you can not listen to anything. I have a very simple fix to allow the drivers to load. I have tested this with the following devices: 

• M-Audio Profire 610 (Firewire)
• Native Instruments Komplete Audio 6 (USB)

The fix is very simple. From the command prompt, enter the following:

sudo nvram boot-args="kext-dev-mode=1"

1	sudo nvram boot-args="kext-dev-mode=1"

Reboot. And you’re done!
Enjoy!
