I created a Mac OS X application but I don't know which steps I have to do for signing my Mac OS X application correctly. Thank you.
I found the Apple documentation far too verbose. I have written up some detailed notes on how I signed my own software for Mac. There is too much to put it all here. See: http://successfulsoftware.net/2012/08/30/how-to-sign-your-mac-os-x-app-for-gatekeeper/
