NO USB M-Audio Fast Track Pro on el capitan?

Thanks but it doesn't really help

When I go to the terminal I get a "No such file in directory" message...so this trick is still working? Closed to put that audio interface in the trash and never buy from M-Audio again.

It happened the same for me, when I opened terminal I've got the "No such file in directory" message. However after copying/moving the drives from the original location as instructed, I've restarted my computer and the M-Audio fast Track Pro appeared listed under System Preferences > Sound > Output/Input drop down list.

Anyway I've also sold my M-Audio Fast Track Pro to a Windows user which I know it stills works without issues and decided not to buy from M-Audio again.

This is what I did to start my m audio fast track pro.It seems to me that this is the simplest solution possible.

1. Download the drivers from the http://avid.force.com/pkb/articles/en_US/Download/Fast-Track-Pro-Drivers

Releases 1.9.5.

2. Mount the ..dmg file

3. Run the uninstallation

4. Restart your Mac

5. Plug in the card into a USB port

6. Do not install any drivers

7. That's all.

For me this solution worked. No need to manually delete any files from the system.

I did exactly the same thing, first removed the USB cable to fast track pro, then used easyfind to remove every file that had "fast track" in the filename, then restart and after plug in the cable back, FastTrack Pro appeared in the list of available outputs and inputs !!

I just ordered one last night. I will post my findings on my 10.12.4 system.
