Reply to X1 Mk1 Not working under OS X Mavericks?

Hi everyone,

I recently updated my computer to the gold master of OS X Mavericks. After the update my X1 Mk1 does't. I really have no idea what to do about this and hoping someone has some ideas. My X1 Mk2 and my F1 works just fine. If I plug the X1 Mk1 into my other laptop still running OS X 10.8 then it works just fine. It's definitely only a problem on this Mac and only after I updated to 10.9.

When I plug the device in it does the typical lighting thing where they flash in sequence for a second and then all the lights go off and stay off. The Controller Editor is not able to connect to the device, Traktor can't connect and the Midi Monitor application definitely doesn't pick up anything coming from the device.

Does anyone have any ideas?
