Can not upload to Arduino from MacBook

Development Tools IDE 1.x

I can not upload any Arduino program from my MacBook.

  • The Arduino is being recognized by my MacBook (USB 3.0-bus).

  • The error message is:
    Using Port: /dev/cu.usbserial-A700dEtV
    Using Programmer: arduino
    Overriding Baud Rate: 115200
    avrdude: ser_open(): can't open device "/dev/cu.usbserial-A700dEtV": No such file or directory

  • I installed a new FTDI driver and the problem stays the same.

  • I tried to upload before, while and after manually resetting the Arduino. The problem remained the same.

  • I used basic programs like "Blink" and did not change those programs.

  • The Arduino works well (both internal and external LEDs blink, but only as result of the electronic circuit on the Arduino itself, and not due to an external program).

What causes the lack of communication between my MacBook and the Arduino?
How do I solve this?
