Still having problems. The driver doesn't seem to be installing properly. I downloaded the one described above and opened and installed it using the same methodology as for the FL programs. The radio is connected to the computer via USB port. I have been able to download both the FLrig and FLdigi programs (having first turned security off to do so, then turning it back on) and can see them on the screen. I can play around with the configuration in each. There are two really nice Utube programs that actually show integrating and IC7100 radio to a Mac. Both parts we are interested in start around minute 26. AmateurLogic 86 which discusses connecting FLrig AmateurLogic 87 which discusses connecting FLdigi When I get to the primary config screen, I can set up both the rig: IC7410 and the baud rate: 19200, but the driver (Silicon Labs VCP) doesn't show up. What choices I have are either NONE or a /dev/cu.Bluetooth-Incoming-Port or a /dev/tty.Bluetooth-Incoming-Port neither of which works. How do I get the Silicon Labs driver to show up on the list. In the Utube tutorial, it does show up. What am I doing wrong on the Mac so that the driver isn't showing up?
