Com port issue on processing 3.3 app on macbook pro

Hello Arduino lovers from beautiful Greece! I'm in front a big issue an I'm on a real rush due to a project I have to show on Tuesday. I'm using an app with name Processing on a macbook pro(mid 2012 a1278 model) and I to put somewhere the name of the serial port.More specifically here:

myPort = new Serial(this,"………….", 9600); // starts the serial communication

In the space with dots I have to put the port I;ve tried to write: com1,com2,usbmodem1411(like the one on the arduino app)but it keeps saying:Error opening serial port(the name of the port):Port not found

Can you help me?

Thank you!

Ok the problem has been solved by me hahahha!!!

The solution is this

in the position of the dots ||
/
myPort = new Serial(this,"………….", 9600); // starts the serial communication

write this:/dev/cu.usbmodem1411

this is the port you are using on the arduino as well, but there you will find it with an extra comment inside parenthesis () whis is irrelevant : (Arduino/Genuino Uno)
so you will only need this.
====>/dev/cu.usbmodem1411<===
if you are using the second usb serial port(closer to you not to the lcd)
Thank you !
