I bought the Saffire on 7 feb 2014 from thomann, Friday worked, yesterday worked only 1 hour and then puf, mac restarted with a " Software problem press a or wait a few seconds " and the error was from audio : BSD process name corresponding to current thread: coreaudiod , I looked from it and checked all the things in mac and it says it's ok everything…. I don't know what to believe…

I'm From Bucharest, Romania and I really need to work with this Saffire again and Fast !!! I don't want to believe that I trow away a lot of money...

Please check what I sent, I have the same problem with the saffire....I really need this saffire work .... I sent a message to focusrite but still no answer... I posted here and still no answer... I don't find the Dicetools to repair myself the damaged mixcontrol..... I updated at the last mixcontrol and it says in Audio Midi : 20 in / 0 out !!!
