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/PlugInssudo mv AppleUSBFTDI.kext AppleUSBFTDI.disablednow reboot ` Download the new driver here: When Ive tried, the last version was v2.2.18: Install the new driver and happy arduino.
