I apologize in advance if this subject has already been beaten to death. The last remnants of discussion seem to end in late 2012 but there does seem to be some development on this issue for PC, just wondering if anyone has any info or insight on this for Mac. In late 2013 Intel seems to have started a program called "Thunderbolt Ready", again it's directed for PCs. I'm in the annoying position of needing to upgrade my Mac but the program/hardware/developer (Avid/Pro Tools) that my professional work is most closely tied to has not yet approved the new thunderbolt Mac Pros and they are often slow to do this, there are no macs of any kind later than 2012 that are approved currently. So, although I have always been comfortable buying last years model, in this case it doesn't make sense because of this discontinuation of pcie and Avid's move towards thunderbolt. I just would like to see if there's a way to use thunderbolt on a 2012 Mac Pro. Thanks.
