No playback from my MacBook Pro to Bricasti M1


My digital front end consist of a Sim Neo 260D transport via balanced AES cable and a MacBook Pro via USB into a Bricasti M1 DAC. Until very recently everything worked great, but now I can't get any playback via the MacBook Pro (cd works perfectly). I tried a different AES cable without any result. 

The M1 no longer recognizes the M1, thus sound only comes out of the MacBook pro's own internal speakers which obviously isn't what I'm looking for. Said another way, the M1 no longer shows up on the MacBook pro's list of available devices.

Anyone encounter this sort of issue? I've reached out to Bricasti and await their response but in the interim- HELP! Your thoughts are appreciated!

New record time for a successful audio repair. Of course it helps that I'm close to Massachusetts. But still- Bricast received, diagnosed, repaired and shipped back my M1 all in one day. The M1 spent more time with Fed Ex than with Bricasti. Shades of old school  Maytag. 
Went into system preferences then sound on the MacBook Pro - it's not letting me do anything but the internal speakers 

Spoke to Apple- went through a few things- My USB ports work and I was told they sort of see something but not communicating. Between Apple and Bricasti I'm sure this will get sorted out. 
Followed the Ayre set up- the Bricasti just does not appear as an available device
I wound up speaking to Brian at Bricasti- called from work. He was already aware of my M1 issue. He suggested I ship the M1 to their factory. It's going out tomorrow-  
My M1 in now en route to Bricasti- when I get a diagnosis I will update- this all is making me consider an Aurender player because somehow I think my M1 got zapped by my MacBook Pro
I shipped my M1 yesterday and in record time, my M1 is now on its way back to me (helps that Bricasti is nearby). No hardware damage but the software was corrupted! The repair was to instal new (and latest) software. My M1 will be delivered tomorrow! Amazing and I want to thank the folks here and the folks at Bricasti for their great assistance. 
It works!!!!!!!!!  Bricasti rocks!  Sent the M1 to Bricasti on Tuesday; it arrived on Wednesday and was repaired and shipped back on Wednesday. Got it this morning, just connected it all up and man oh man, it's 100% 

I've had exceptional and speedy service over the years from Bryston and Pass in addition to Bricasti. My Linn gear has never needed to be repaired, which is great too-
