Hey,

it happend to me few times already and I am really starting to hate it. I have few Arduino Boards (UNO, Duemanilove, Leonardo), and all of them sometimes restart my computer when uploading the program.
I have Macbook Pro 13" mid 2010. No other devices are attached. Anyone has an idea?

Regards

What is attached to the board(s)?

That is one of the most bizzare problem symptoms I can recall reading about. Don't have a solution for you. Possible problems:

Flaky intermittent power problem with the USB ports causing a hardware reset in your Macbook?

It is indeed very weird. Sometimes the reset is immediate, last time the video I was watching started stuttering and than the computer restarted.

That sure sounds like a USB power problem in the apple's hardware to me.

Only when uploading?

What about verify (upload is not performed)?

No, only when uploading. I don't think this is a software issue.

The primary difference between uploading and not uploading is software.  Why would you believe that can't be the culprit?

mrkva

I don't understand. It doesn't happen when verifying. It happens when uploading - during the 'uploading' part of the process.

The culprit might have something to do with the fact that the uploader sends a
Reset pulse to the Arduino, and there may be a fault in that ckt. Does the problem
still occur when powering the Arduino bd from an external supply via the power jack?

The time I had an Arduino bd resetting my notebook, there was a short from the
USB power pin to the external power pin. The PC would completely shutdown when
I connected the external power source to the bd.

mrkva

Yeah, I know that might be an issue sometimes. But now the arduino wasn't connected to anything, powered from the computer. I guess it must be fault on the motherboard of the computer.

One of my notebook PCs does have a blown USB port, so there's always a possibility of
a fault there. However, I also asked

Not necessarily a fault, just inadequate power at the port. You are exceeding the specification. And it's not exclusive to your macbook either. I recently replaced the mobo in my desktop and was horrified to find it refused to start the next morning. It turned out that the Arduino was the culprit.
