I'm new on Arduino
My Arduino IDE no have /dev/tty ports option, only /dev/cu
I'm looking for solutions to 4 days ... 
on Mac OSX 10.10 and Arduino UNO
We filtered /dev/tty out since 1.6.2. If you wish to renable them, close the IDE, edit file preferences.txt (location is on File > Preferences) then ensure there is the following line
serial.ports.showall=true
Restart the IDE

It will still work fine to upload to that port. Have a nice day!
