trying to download an arduino program in Yosemite and not working?

The FTDI driver Apple wrote is the culprit.


disable the Apple FTDI driver first

cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled

now reboot


Download the new driver here:

When Ive tried, the last version was v2.2.18:

Install the new driver and happy arduino.
