i did everything listed Solution (as partially provided by the website above) Type the following commands into the terminal: * cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns* * sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled* * sudo touch /System/Library/Extensions* Restart your computer Install the original FTDI Virtual Com Port drivers found here: http://www.ftdichip.com/Drivers/VCP.htm Start Arduino and program as you always have. but it does not work, I still get the same problem compiling. Am I installing the right driver? When I visit the link above I couldn't find a 10.9 version in http://www.ftdichip.com/Drivers/VCP.htm
I have both the D2XX and VCP Drivers installed, I have tried them individually installed at a time and it didnt work too.
