i tried connecting an arduino uno on my mac and it doesn't even show up the serial port. i tried installing the ftdi drivers also but didn't work so please help me out
Uno doesn't use FTDI driver, it uses Atmega16U2 programmed as USB/Serial interface.
Check the chip next to the USB connector - what does it have marked on it?
i didn't get you! what am i supposed to do? what sort of driver do i need to download can you explain it elaborate please
Arduino: 1.6.5 (Mac OS X), Board: "Arduino Uno"
Sketch uses 450 bytes (1%) of program storage space. Maximum is 32,256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.
avrdude: ser_open(): can't open device "/dev/cu.wchusbserial1410": No such file or directory
ioctl("TIOCMGET"): Inappropriate ioctl for device
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
Sorry, I'm not a Mac user. I don't know what this means
avrdude: ser_open(): can't open device "/dev/cu.wchusbserial1410": No such file or directory
ioctl("TIOCMGET"): Inappropriate ioctl for device
other than perhaps you have a driver problem.
yeah it seems i have a driver problem but can you like help me where to find out the exact drivers for arduino uno for mac!!
I cannot. I only use PCs.
ughh.. can some one else sort me out this problem please
I have the FREAKIN problem as WELL! Yesterday it was working fine and today it wasn't!!!!
yeah this happens every time on this mac
avrdude: ser_open(): can't open device "/dev/cu.wchusbserial1410": No such file or directory
What ports actually show up in your "port" menu. The name there implies an unofficial Arduino derivative using a CH340G usb/serial chip, rather than a genuine arduino. You'll have to install the CH340G drivers, which apparently requires some special steps if you're running Yosemite or later. See http://kiguino.moos.io/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.html
But I'm not sure how you'd see that device name at all, if you hadn't had the driver installed at some point.
Searching for "ch340g" might find you additional info.
i can't view my serial ports using El Capitan and arduino 1.6.5 software, please help.

i have similar problem for OS X 10.9.5, it does not show me tty ports 
only cu.usbmodem1421 for device.
