I downloaded Betaflight Configurator for Mac, version 10.5.1. I installed the CP210x drivers. My Mac already had the STM USB VCP drivers. I connected my Tinyhawk to Betafight and was able to repositon information on the OSD. However, since that first successful connection, I can't connect again. When I hit the Connect button, I get the message "Failed to open serial port." I don't understand why I was able to connect to my Tinyhawk the only the first time I tried to.
