I have a spider valve mkII and use spider valve edit and I had the same problem. I also bought a new midi to usb cable with not luck. What worked for me was reinstalling the driver(s) for the midi cable then opening line 6 monkey (at this point I checked that all my firmware was up to date), then I opened spider valve edit and then the MacBook Pro recognized the shortboard. My MacBook is a late 2010 running Mountain Lion 10.7.5. I hope this helps, Good luck.
