Using OS 10.10 Yosemite... on a Late 2012 Mac Mini i5 with 4GB. ShowXpress will not recognize my 2 Xpress 512 interfaces with version 9 beta or version 9.1. It works perfectly in 8.2.28. I can't seem to understand why.
Unfortunately we do not have Yosemite, but we have Mavericks (10.9) which is one version older than Yosemite. And our Mavericks finds the dmx interface. So there is a good chance it works with Yosemite as well.

Oops my mistake! Should have read the post properly
