I am using a MacBook Air for MacLogger, WSJT-X, and Winlink (Crossover). I was using MacLogger successfully until I loaded Winlink. Winmore was controlling my rig until I installed VARA and tried to assign a port (COM 1: /dev/cu.SLAB__USBtoUART). The VARA TNC does not find the port, Winmore has lost rig control, WSJT-X continues to control the rig successfully. Now MacLogger can see the SLAB ports but won't connect the radio. I have also noticed that the port changes from ...UART to ...UART1, or even ...UART4. I am ready to dump Crossover and Winlink and forget about emergency communications and stick to SSB logging and FT-8. Any help would be appreciated. I am using my IC-9100.
