CCAT

Hi Guys,I have been following this string of posts a couple of weeks ago and it solved my issues with my Mac and the conflicts with the latest OS. Out of the blue no signal would get to my interface from the mac. I upgraded the driver and had the crashing issue and the latest upgrade that I got from this thread seemed to fix it. My system worked perfectly for a couple of weeks and now it seems to have the same problem that I started with where no signal is going to my interface again. I have tried re installing the drivers again, but I am having no luck at all with this. Any ideas?
