Pressing "erase" is the only thing needed, no need for "reset" too. Not a pretty workaround, but it works. ;-)

James C4S: Tried the /var/lock trick, but it does not work.

Creating a /var/lock looks like a weird, non-correct solution too OSX uses /var/run.

James: The verbose mode does not provide a lot of more info:

I can confirm that the trick Amicus posted about does work (for me). Pressing erase and then reset makes it possible to write a sketch to the Due. This has to be done every time a sketch is to be written/downloaded to the Due. As a work around it is ok, but points to something fishy.

Could you describe a bit more what you removed?

I'm having similar issues interfacing Due in OSX 10.8.2. I can get it to work in Windows 8 running in Parallels, see:

(Replying to myself.)

I've tested running the Arduino SDK 1.5.1r2 in Windows 8 Pro in a Parallels VM with the same OSX 10.8.2 as host OS. Arduino in Windows is able to talk and upload sketches to Due without any problems (after disabling drivers signatures in Win8). So, the problems seems really to be with how OSX handles serial ports and how the Arduino SDK expects them to work.

Anybody have any ideas how to resolve this?

Aloha!

I few days ago I got my new, shiny Due (wohoo). However I'm having problems uploading sketches using the Arduino development environment to the Due.

When I connect the board using USB-cable the HW Growler (http://growl.info/documentation/hardwaregrowler.php) shows that the "Arduino Due Prog. Port" has been connected, so it seems that the board is recognized by the system. Also, when the board is connected, /dev is populated with a tty.usbmodem1421 device.

I've downloaded the beta version of the Arduino development environment (version 1.5.1) and I can select Arduino Due (Programming Port). I can also select the tty.usbmodem1421. There is also a cu.usbmodem1421 port that I can select. But no matter what port I select, I get "No device found on tty.usbmodem1421" when trying to upload a sketch.

My machine is a mid 2012, Ivy Bridge Air running 10.8.2.

Any suggestions, pointers and help solving this problem greatly appreciated.
