Just starting with Arduino and have gotten stuck at the first hurdle: trying to connect an Arduino Nano with my Mac Book Pro which runs 10.10. I can't seem to find the right port as all suggestions have bluetooth in the name and none with USB anything. Also the post list does not change when I plug/unplug the Arduino. Looking at http://arduino.cc/en/guide/macOSX#toc3 it says that I need to install FTDI software to get the USB port to show, however, having done this it still does not work. Any suggestions?

Thanks, Calum

This question came from our site for professional and enthusiast programmers.

  • If this is a genuine nano from arduino.cc then the FTDI driver is what you need; if it is from someone else it could require a different driver or not be functional at all. If you do apple-about_this_mac-system_report you can see a list of USB devices, if you can find the VID/PID associated with your board and add it to your question or do a web search on it that would help a lot. – Chris Stratton Feb 24 '15 at 15:45

Had exactly the same problem. Also using 10.10 and just got an Arduino. What worked for me was using a different cable. The one that came with my Arduino Uno only provided power not data. If you have a printer, it might have the right cable, just test it quickly.

Edit: In addition, whilst trying to find solutions, I also installed 64bit mac FTDIUSBSerialDriver_v2_2_18.dmg. I'm not sure if it made a difference. As after installing it and using the original cable the problem persisted.

  • Hopefully that was not an official board but a knock-off, if the cable it came with was bad. – Chris Stratton Feb 24 '15 at 15:43

Are you using a USB hub? I had problems with my MBP when the Arduino was on a hub. Attached directly to the mac it was fine.
