NSConnectionDelegate methods doesn't be execute - macos

Question

I'm trying to develop a simple OS X application that should do the following:
Read a file to get username and password
Obtain Mac serial number from server
Connect to a remote service to login with username, password and Mac serial number
If the user is authorized to be connected with this service it should run an infinite
Infinite loop should call a service that connect to another service to get news
If there are news it should send a local notification
This application should work without GUI, so I'm using an Xcode command line tool. The application is organized so:
main.m read file with username and password and obtain the Mac serial number
Connection.m should connect to the login service and run the checkNews service
CheckNews.m should connect to the news service and if there are a news should run a class to send local notification
NotificationCenterDelegate.m should simply send the local notification with news inside
My problem is that if I run the app it doesn't connect to the login service, because it doesn't calls the NSConnectionDelegate methods. I searched on the web and I found that the connection should be in the main thread, I tested it by using the following code: NSLog(#"Is%# main thread", ([NSThread isMainThread] ? #"YES" : #" NOT")); and it returned me that the connection is in the main thread, so I don't know why it doesn't run the NSConnectionDelegate methods. If you need I can post the code of my Connection.m class to understand why it doesn't working well. I hope you can help me to fix that issue.
