There doesn’t appear to be an official OS X driver. There’s an unofficial one at https://www.mac-usb-serial.com/ but it costs 7x the price of the device….

Very good price and works perfectly. Using them program ESP8266 modules.
Works absolutely great for the price! Remember to download the recommended driver via http://www.wch.cn/download/CH341SER_EXE.html
and consider to press the reset button while uploading your program.

Works like a charme. (Don’t forget to use the driver ‘njnazim’ desribed) I have replaced te 6-pin single-row male connector by a 2×6-pin double-row connector. I wired DTR and other signals to the second row. Now I get the ‘automatic reset’ like on the original FDTI board. Really a nice little board. Using it for programming Mini Pro and others.
