Feb 25, 2017 In OS X it seems to be unknown, however, the USB Device Tree reports the FT232R USB UART correctly with Product ID and Vendor ID from FTDI. But I want to get rid of the Win (VM) solution and installed the FTDI driver for Mac, didn’t work. As suggested by FTDI for Mavericks. Also, as of Mac OS X 10.9, Apple began shipping their own FTDI driver. So, if you're using a USB-serial adapter that uses the FTDI chipset (many of the higher-end adapters do), you don't need to worry about installing drivers and can use the built-in screen command in the Terminal to access serial ports.
I’m on Mavericks (10.9.5) and fighting with a USB device with a “FT232R” chip (from FTDI) for USB to serial conversion.
It was not accessible in OS X (e.g. QuickTerm didn’t list it, only the Bluetooth Port + Modem).
Using an old Windows (in a Parallels VM on the same Mac) I could (and still can) access the device, switch it back and forth between OS X and Win, and send commands to it using a terminal SW.

Ftdi Driver Install
As suggested by FTDI for Mavericks
[ http://www.ftdichip.com/Support/Documents/AppNotes/AN_134_FTDI_Drivers_Installat ion_Guide_for_MAC_OSX.pdf ]
I have also disabled (renamed) the AppleUSBFTDI.kext, restarted and installed the FTDI driver (version 2.3, signed by Apple). The installer always tells me “success” but I still can’t see the driver /System/Library/Extensions/FTDIUSBSerialDriver.kext (should it be there?) and the device isn’t accessible from OS X.
I’ve tried again and again, there is no FTDI or USBSerial device listed in /dev when I plug it in or switch it back from Win - I guess because the (OS X) driver isn’t correctly installed?
