Arduino with Mac OS X Yosemite

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.
