programmer is not responding - MAC OX mavericks 10.9.5

When connecting my arduino nano AT328 for the first time i get the following message when trying to upload my code on OX mavericks

avrdude: stk500_recv(): programmer is not responding

In the serial port menu i see only bluetooth ports.

I have done:

  • installing and reinstalling of FTDIUSB serial driver v 2 2 18

  • typing the following:
    cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns
    sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled
    sudo touch /System/Library/Extensions

  • rebooting

Still nothing works and my arduino green light: on , red light: flashes

Any suggestions??
Thanx in advance
