Arduino UNO R3 and OS X 10.8.4 - Uploading Problem

Like some other people, I haven been able to upload my sketches to my Arduino UNO R3.

I have done a bunch of tests already:
1: The board shows up in my network preferences and my system profile:

2: I have the correct board selected in Arduino: (Arduino UNO); I also tried the Arduino Duemilanove setting.

3: I have tried other R3's, same issue.

4: I have tried other USB cables. Problem not sovled.

5: Board, cable and uploading works perfectly under OS X 10.6.8

When I try to upload, I get the following error:

avrdude done.  Thank you.

Is there anyone out there that is able to point me in the right direction?

Hello peterpixel,

I have the same problem, did you find a solution?

In my case I found a weird one (partial solution) which is to plug the arduino to a hub (apple long keyboard with usb plug). In that way is possible to upload you code but when you use 5v energy as normal is automatically disconnected.

I hope you find a better solution.



I had a similar issue with an Arduino Mega 2560 r3:

avrdude: stk500v2_ReceiveMessage(): timeout

I had to burn the bootloader again using an AVR-ISP-Programmer.
