OSX 10.9 Leonardo Serial port Not Showing

Development Tools IDE 1.x
1

Hi Everyone,

I'm running Mac OSX 10.9.5 on a macbook pro retina. I just bought a new Leonardo, but when I connect it to the computer through USB, I dont get ANYTHING under the serial port menu (what it looks like is in the screenshot attached - named "A"). As a result my computer cant upload with the Arduino. When I plug in my Mega2650, it works so extremely smoothly - its immediately detectable no issues at all. I've been having the same exact problems with my UNO as well.

However, just like with the UNO, when my Leonardo is plugged in, although I get the result as shown in attached screenshot "A", in the actual IDE window however it reads the usb serial port (screeshot "B" attached). When I click the upload button, for the case of the UNO as well as the Leonardo, but never at all with the mega, I get the result as shown in attachment "C".

I did A LOT of searching and what I have so far is some issue with the new apple serial drivers introduced in OSX 10.9. Also I noticed that in the ftdichip website, when you download the VCP drivers, the packages included in the .dmg dont mention "10.9", instead only one package for "10.3" and the second package for "10_3_10_4_10_5_10_6_10_7_10_8" or something along the lines of everything up till 10.8. Maybe this is one of the issue's, I'm note sure.

I read through and followed the instructions at this link (http://forum.arduino.cc/index.php?topic=198539.0), but that hasn't worked out for me at all. Maybe something to do with driver confusion?

This has been a real headache, and I'm in real need of a fix as I'm using the Leonardo for an important project. Any help would extremely greatly appreciated.

Thanks!! :smiley:

Just to be sure: You disabled the old (Apple's) Kext?

Looks like it. According to the intructions here http://forum.arduino.cc/index.php?topic=198539.0.
One thing though: When I put the second line in terminal, It says "mv: AppleUSBFTDI.kext: No such file or directory" (screenshot attached, named "D").

What I then did, is instead of putting in "sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled", I entered
"sudo mv AppleUSBFTDI.disabled" ---> so thats without the AppleUSBFTDI.kext.

Likewise, very frustrating, doesn't seem to be any solutions - Yosemite? -all my machines are on 10.9.5 now and I can't send code to the arduino :frowning:

I have a bt dongle I might even have to figure that out at this rate

Ok this is only on the Doodle Bot board (NG ATmega 8 I think) the UNO is loading tty.usbmodem1411 and cu.usbmodem1411
