Hi.
I am trying to connect my arduino nano v3 with my new macbook pro.
I have followed the instruction offered by this tutorial:
http://arduino.cc/hu/Guide/MacOSX#toc1
My problem is that the tutorial says that you need to select /dev/tty.usbmodem but strangely enough i get only the bluethoot modem selections and no serial or usb modems are available.
I am using the latest lion OSX.
Can you help me out... Thanks.

Did you install the FTDI drivers in Step 3?
I got a Arduino Nano v3.1 a few weeks ago, hooked up to my iMac, and it also had the same problem. With the Nano hooked up, "ls /dev/tty.*" gives me /dev/tty.Bluetooth-Modem /dev/tty.Bluetooth-PDA-Sync . The blue LED light is lid and the orange LED blinks as it should but the Arduino IDE does not recognize the port when I have the "Arduino Nano with ATMega328" selected under Tools > Board. The only options available under Tools > Serial Ports are /dev/tty.Bluetooh-PDA-Sync, /dev/cu.Bluetooh-PDA-Sync, /dev/tty.Bluetooth-Modem, and /dev/cu.Bluetooh-Modem.
I've installed FTDIUSBSerialDriver_10_4_10_5_10_6_10_7 that I downloaded at http://www.ftdichip.com/Drivers/VCP.htm on my iMac and it does not recognize the device. I've also tried the same process on a Macbook Pro with the same results. I've also tested the same Nano on a Windows 7 box and it recognizes the Nano with no problem, so it's not a hardware issue... but I would like to get it working on my iMac.

Without the Nano connected, open System Profiler.
Lion: Go to Apple -> About This Mac -> More Info... -> System Report
Pre-Lion: Apple -> About This Mac -> More Info
Click the "USB" section.
Connect the Arduino and select File -> Refresh Information (or CMD-R)
Did the FTDI device show up, if so, how was it named?
Thank you for the prompt response and suggestion. I followed your instructions and it did not appear in the system profiler before or after the Nano was plugged in. See attached screenshots. I unplugged and plugged in my iphone and it did disappear and reappear in the system profiler.
Did you buy it off of eBay?
I purchased both my Nano and Uno from Make.
In that case, you might consider returning it. It should show up in Profilier whether the device driver is installed or not.
Another thing to check is run dmesg at the terminal when you attach it. OSX might be giving up on enumeration before Windows does. Dmesg will tell is the USB system is complaining.
gabewong81,
were you able to resolve this? i'm having the same exact problem on my macbook air running 10.7.x.
i installed the FTDI drivers, rebooted, and although the nano is getting power, the serial port isn't working.
i can connect to my duemilanove and uno boards no problem. it's just the nano v3.0 that i'm having trouble with.

Had identically the same problem. Nano V3 worked AFTER loading the FTDI drivers and then next session USB port was not visible or could be selected. Tryed reloading FTDI drivers on 2 separate computers and the USB driver was not there but power light was on Nano. Long story short, it was the USB cable that came with the Nano. If you cannot see the FTDI chip from System Profiler under USB, I would recommend start trying different USB cables.
I did this and I got FT232R USB UART.
What does that mean?/What do I do next?
Thanks
PS: Im working with the Arduino Pro 5V ATmega328

If you installed the FTDI drivers already, this means you will see a /dev/tty.usbserial-XXXXXX listed in the serial port menu of the Arduino.
Hey,
I've got the same problem.
I Bought two Nanos and connected them with 3 different USB-Calbes.
My Macbook Pro finds the FTDI drivers.
Now I use the Arduino-Programm and can't upload sketches, that work on the Arduino Uno.
Unless the Arduino shows the dev/tty....-A603RTIG as possible Port.
Basic blinking works on both Nanos.
Hope you can help me out.
The "..." Part of the device name is the critical section. Uno will show up as "usbmodem" and FTDI based devices will show up as "usbserial".
Assuming a genuine uno, there is no common USB hardware between a nano and Uno. So one working really means nothing for the other. They used different implementations.
If I your uno is connected and you see a "usbserial" device, either it is not the Uno or it is not a genuine uno.
I hate repeat but I am having the same problem and I also got FT232R USB UART when running the System Profiler.
However, I am not sure if the FTDI are installed or not, here is a picture to show that the Arduino Nano is showing up.
But when I go to the Arduino Software, it shows no port for the Nano.
Please help and I really want to do some programs on the Arduino Nano.
Same here, no resolution. Summary:
FT232R USB appears in 'USB Device Tree', no serial port ever appears in /dev/tty* or /dev/cu*, nor is there anything relevant in via 'sudo dmesg', nor does it ever show up in arduino IDE.
I have both latest drivers from http://www.ftdichip.com/Drivers/VCP.htm and have also tried old drivers from arduino 0.2 (though they are the same).
It works fine in Linux. I worry that there is something unsupported in OS X 10.9.3 that does not allow the FTDI drivers to work.
indeed - there is a conflict with 10.9 drivers - see here: Arduino in OS X 10.9 Mavericks - Serial Port Issues - IDE 1.x - Arduino Forum
unfortunately the solution did not work for me... thus, I'm in linux & works great.
I'm having exact same problem as reported on page 1
The FTDI driver didn't work for me, too.
But that driver did work:
Maybe this will help someone else.
There seem to be some different boards that need different drivers.
Emale,
this helped me a lot! thank you so much.
Btw, my system information describes nano as USB-Serial Controller:
and now it's displaying port correctly:
