How do I get a unique identifier for a computer with cocoa? Or how can I tell that my application is running on a different machine?

MAC address seems like a good choice here.

From the terminal you can do ifconfig en0. You can make a system call and parse that. I don't know the Cocoa API but I assume Apple will have a wrapped that too, potentially here:

A MAC address can be changed. Don't use it for security applications.

There's a little code.

I guess you could also get the serial number:
