OS X Mavericks 10.9.1

Please provide any additional information below.
I installed the drivers from http://www.ftdichip.com/Drivers/VCP.htm

EDIT: Solution

I just found a workaround. It consists of disabling the Mavericks included 
Apple FTDI drivers (or whatever). I was successful after disabling the driver 
with the following FtdiDriverControl tool:

RTANT

After that, drcontrol worked like a charm for me on Mavericks (after following 
the specific OS X instructions from the Wiki) :)

(Additional info: I also tried the following "manual way" before that, but it 
did not help for me: http://forum.arduino.cc/index.php?topic=198539.msg1464718)

Thanks for your work!
