FTDI / USB to serial. AVR programmers, etc.

I have a Sparkfun ESP8266 Thing Dev board connected to a MacBook pro via USB C. In the Arduino IDE there's no port showing up.

I installed the FTDI drivers as instructed on the sparkfun tutorial and rebooted just for good measure. That still didn't work.

I found this post suggesting that Apple's AppleUSBFTDI.kext FTDI driver was conflicting. I rebooted in recovery mode, moved AppleUSBFTDI.kext to my home folder, and started up again. I still don't get the port showing up.

I've checked with
ls /dev/tty*
and the VCP does not show up. Nothing shows up in my USB device tree (System Information -> Hardware -> USB) either.

Anyone suggestions of what I should try next?

I don’t have exactly the same configuration as you, but am struggling with a similar problem; I have a MacBook Pro running Sierra and two Arduino boards; an UNO that’s probably four or five years old and a new SparkFun RedBoard. The Arduino IDE recognizes the old UNO, but not the RedBoard.
