First off i have a NCE pro cab and the sub interface and cables and such I am using a MacBook Pro with Yosimite os, and reading the download of the software to run jmri I need the NCE sub interface software, the instructions say install this driver first and then jmri. The problem I'm having is , I install the driver and open it , that's fine I think, but when I plug in my interface my Mac isn't recognizing I pluged anything in. And when I download jmri, that downloads and opens but when I click on anything in the program, it reads, Error or NCE program error or something like that, and I heard when this happens I have to uninstall both jmri and the sub driver and do this again. Well I've done this a few times and to no avail it's always doing the same thing. Any ideas?😡
