Cannot get Betaflight Configurator to work on MacBook Pro

Often the problem in connecting a drone to betaflight is that the usb cable is not a data cable, but I am certain that mine is. I can transfer files back and forth on my kindle using my micro usb data cable. I bought a new one from Amazon but I have the same issue. I successfully installed betaflight and the requisite drivers, but it still will not connect to any of my drones. I run OS Catalina. Any ideas, other than the cable? Thanks
