Hello all..

Currently I have an analog summing box that I use to finalize my mix and print in order to color up my mix with some analog gear..
For my macPRO set up .. I have a
1. shadow hills equinox
2. Antelope Isochrone OCX Clock
3. SSL Alpha Link SX
4. Barefoot MM27s
5. KRK vxt8's

However these days I find myself pumping out more and more mixes on my laptop.. As I update my plugins more often on my laptop than on my mac pro.. The problem I had was that I couldn't print my mixes using the equinox unless I got a RME Madiface HDSPE.  So I did.. .. for my Macbook Pro.. My setup is basically the same thing without the mac pro.. However for some reason I tried using it today and its not working..  The sound plays for like 2 seconds and then cuts out..

Does anyone know what I need to do? Can someone point me in the right direction in order to make my equinox work properly with the mac pro and macbook pro whenever I feel I need to use either or? 

I need to finalize this track and this madiface thing is really messing my flow up

Any help would be GREATLY appreciated!!
