Ive got a question that may or may not have a simple answer, and it has to do with figuring out the URL from which a program is downloading its updates so that I can download a backup of the installer. The program in question is KeyRemap4MacBook, and the stable release version can be found here. But within the program, there is also a button to check for beta releases. The beta versions are not listed on the website as far as I can tell. So what I want to do is somehow watch my computers network traffic when I update to the latest beta version, so that I can see what URL the beta version is downloaded from. Whats the best / simplest way to do that?
