Logic Pro X will not see my Audio Interface
First use of Logic Pro 10 on new install. It does not see my Presonus Audiobox USB audio Interface. Here is what I tried in multiple combinations and iterations.
I click Core Audio and unclick it, try to find Presonus on drop down but it is not there. My only options are Built-in Mic and System Setting. I swapped cables. My external Midi keyboard controller works fine so I know it isn't the cables plus my usb microphone works okay using same cable. I did a Mac install on Presonus website and installed firewire drivers for USB-C but makes no difference.
I am running out of ideas on how to get it to work. Not sure if MacBook Pro has any other settings elsewhere so that the Audio interface can be seen. Powered down and up on each iteration.
