No such file or directory

Hi , i just got my

:slight_smile: Plumduino Maker Board!
I have followed the guide with the installation, when i plug it in my iMac and arduino running i get avrdude: ser_open(): can't open device "COM1": No such file or directory.
I have read other topics but couldn't find any good explanation for how solving this issue.
Does any one know how to solve this or is it just waste of time , i mean i can still use it for the LED fun of it but i am not able to program until i can fix the issue i am having.
Thanks in advance!

Problem solved!!

Please select your Arduino's COM port from the Tools > Port menu. If the menu is disabled then you may need to install the driver your your board.
