I've been using an official FTDI driver on 10.8, 10.9, and 10.10 without issues.

Same here, never had any trouble with the official FTDI drivers on Mac OS's. I use Sparkfun FTDI board too (older, green PCB).

Did you check after connection of the board, with Terminal:

Code: Select allMac-mini-van-gerard:ESP8266 gerard$ sudo dmesg
<big snip>
FTDIUSBSerialDriver:        0  4036001 start - ok
FTDIUSBSerialDriver:        0  4036001 start - ok
FTDIUSBSerialDriver:        0  4036001 start - ok
FTDIUSBSerialDriver:        0  4036001 start - ok
FTDIUSBSerialDriver:        0  4036001 start - ok
Mac-mini-van-gerard:ESP8266 gerard$

OR

Code: Select allMac-mini-van-gerard:ESP8266 gerard$ ls /dev

The FTDI board is the cu.usbserial-A4….

I'm not sure how to uninstall the driver. is that what i should do?

- Sun Nov 30, 2014 4:57 am #3588 That's not looking Good.

First try to install the driver from FTDI and then reinstall. I believe there is an procedure in the install download.
