But: still open: how did it work in Yosemite without having installed the driver ...  ???
Honestly don't know, I had yosmite installed when I downloaded the Arduino IDE, and things just worked, it was only after I installed El Capitan that I suddenly noticed my project was no longer connecting to the Ardiono, so I hooked up a spare Arduino board I had also gotten from eBay and then I discovered that I could not upload our project sketch because the port was reading as a blue tooth input device.

Thankfully your solution of downloading and installing that driver seems to have cured the issue.... But yeah from the get go I never had the problem with Yosemite O.S. Only when I upgraded to El Capitan.
one Artist CAN make a difference.


Hi, I have a similar problem.

I have Sierra 10.12.1 on my MacBook Pro (13-inch, Early 2011) and I cant get a different port than "/dev/cu.Bluetooth-Incoming-Port". It drives me desperate as I can not upload anything anywhere.

I have read the previous posts, even tried the post #23.


Pls use the search function here in this forum. There are quite a lot of new tipps how to solve that issue.
It seems that you need an Apple signed driver to cure that issue - depending on what board you have resp. what communication chip is on board.
Before you ask:
Did you really read and understand "How to use this forum"  -> http://forum.arduino.cc/index.php?topic=148996.0
Do you have already some solution or is a part of the problem sitting in front of the screen?  :)


I had the same problem of no Mac port to choose for the MEGA 2560. (MAC OSX, 10.8.5 )

1) Fired the Arduino 1.0.5 , Connected the Arduino to a USB port

1) I went to tools/BOARD and choose (don't ask me the rationale) another BOARD model  which has the choice of
serial ports

2) went to tools/SerialPorts and selected /dev/tty.usbmodem621

3) went back to tools/BOARD and selected the right one (i.e., MEGA 2560).  

Everything is working…

Don't ask me why….

Had this problem on my 2015 Macbook Pro.  I tried this method cuz it seemed easiest and it worked.  Thanks!
