M-Audio Interface Compatibility on Newest Mac OS

[bhoggard]

I recently purchased a new Mac Mini running on OS 10.9.4, and am having quite a bit of difficulty getting Pro Tools 10 to recognize my Interface.

I am running an M-Audio Fast Track Ultra 8R interface, and have downloaded the latest driver from their page. Pro Tools 10 will not recognize the USB Interface in the software.

In researching, I found the latest information from AVID about this particular interface and drivers:

(version 2.3)
Nov 20, 2013
Mac OS X 10.9 - 10.9.2 Mavericks support only
Mac OS X 10.9 Requires Pro Tools 11.0.3 or higher
Mac OS X 10.9.1 Requires Pro Tools 11.1.2 or higher (added 2/7/2014)
Tested with Avid-qualified Apple computers

I am curious whether there's a compatibility issue with Mac OS versions later than 10.9.2, or if I need to upgrade to Pro Tools 11.1.2 or higher.

I had this same interface successfully in use with the same version of Pro Tools last week on a PC computer, but since transferring everything to the Mac it won't connect. At this point, I'm not sure if it's a Mac OS or Driver compatibility issue.

Any advice?
