I am a new user to DCC as of last year and new to the users group. I have the NCE PowerCab and the NCE USB interface. In September 2017 I downloaded JMRI onto my wife's Mac, OSX 10.11.6 and DecoderPro worked fine. About three months ago it stopped working. I re-installed the latest drivers from SiLabs and JMRI 4.11.6 and it still did not work. More technical and experienced people, including Ed at NCE, walked me through my settings and found nothing wrong. Ed suspects that the Mac has explicit security permissions for the USB port and that the OS is blocking the hardware and driver.?
Here' s more detail. With DecoderPro running, the message on the lower bar says NCE is online. When I ask it to identify a decoder, the message bars says it is reading CV29, but nothing happens. If I click it again, the message bar says the programmer is in use.?
The LEDs on both the USB and the layout sides of the interface flash occasionally. The cables check out okay.
I found an email from Dave of Australia about opening the System Profiler on the Mac to check if it is seeing the USB interface. My 21 year-old daughter did so and found it on the System Profiler. (Though it does not show up in the Finder.)
Dave's email gave instruction to open a Terminal Window and paste in a command "while : ;do clear;ls -lt /devlhead;i=$((i+1));echo $i;sleep 1;done" My daughter did so and reported that it could not find /devlhead; the command generated no lines of output though it counted.?
Any help would be appreciated.
Thanks,
