no dev/tty ports listed

Development Tools IDE 1.x
1

I have OSX Mavericks and just acquired a MEGA ADK and am trying to do the "getting started" exercise with IDE 1.6.5 (downloaded yesterday).
In step 8 there are NO dev.tty ports listed, only dev.cu (dev/cu.usbmodem411) and some Bluetooth.

I went back and tried to run my Duemilanove and got a similar result (dev/cu.usbserial-A900GBUX)

When I do " ls /dev " in Terminal it lists the two dev/tty.usb* ports but they are associated with dtrace and dtracehelper.

Will I have problems if I use the dev.cu ports? Is there a way to free up the tty ports from dtrace?

tty ports are filtered out on purpose: having the same port twice confuses students at classes. If you can't live without them, close the IDE, edit file ~/Library/Arduino15/preferences.txt and add the following line
serial.ports.showall=true
Save and close the file, reopen the IDE
