Hi there,
I´ve read your
Please check the troubleshooting guide before posting here Guide, but my problems remain.
I have a ArduinoMega2560 R3 and I´m using MacOS 10.8.2. At the beginning there was no usbmodem or whatever (I´ve just had 2 red lights on my board).
So after checking my SystemProfile (my USB-port), I just found ATmega16u2 DFU.
t
brew installdfu-programmer
dfu-programmer atmega16u2 erase
dfu-programmer atmega16u2 flash Arduino-usbserial-atmega16u2-Mega2560-Rev3.hex
dfu-programmer atmega16u2 rese
Now I have a /dev/tty.usbmodem411 and a /dev/cu.usbmodem411.
Uploading something doesn´t work

It also doesn´t work with tty.usbmodem411
But now I don´t find any useful information about how to go on further?
Small update:
Now It´s a usb communication device in my system profile (USB)

I know it´s German, but I think you get the point.
So now what? (Still 2 red lights on my board and this failure message above)
best regards,
