Arduino Uno - macOS

[johnny26]

Hi,

I need help to find out what I'm doing wrong, I have a MacBook and can't upload a simple blink to my Arduino Uno R3(I have the original but its the same for a Chinese copy), I know they are working, because they work just fine on a windows PC, the Arduino IDE finds the Arduino and recognize it, but doesn't upload...
However I've tried whit a Arduino Mega 2560 and it works.

Ive checked the cable, USB port, I got nothing connected to the Arduino board, already burn bootloader,
I think is something to do whit drivers.

This is the error I get

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding

it goes on...

Arduino show as this..

Is the right board and processor selected, it might also not have a bootloader pre installed, but since you seem to have a other Arduino you should be able to burn the bootloader using this link. Installing an Arduino Bootloader - SparkFun Learn

yes I have the right board selected, I've burn the bootloader to the Arduino using a USBtinyISP and that works fine, but the Arduino it self connected to my Mac doesn't receive any upload (the Arduino works fine on a windows PC).
