Hi, I an a newly coverted Mac user after 20 years on a PC. I have been using a PreSonus Audiobox USB Audio Interface on my former PC. According to the PreSonus User Guide Installation instructions for Mac OS X: "The AudioBox USB is a class compliant core audio device. No driver installation is necessary. Simply connect your AudioBox USB to your computer." I have done this, but my Mac Mini does not "see" the AudioBox interface at all. Thus, I cannot select the Audiobox in the Audio settings, etc. It's like it's not there. Anybody have any advice?
