Do you remember the incredible Welcome Video on Mac OS X Snow Leopard? Does anyone know how all this is achieved? I mean the principle of how to get the video to play automatically the first time one tries to log in to a New Mac. Any suggestion would be appreciated. Thanks.

1I'm voting to close this question as off-topic because it isn't really about Apple hardware or software, it's about how to learn to produce animations. – Tetsujin Nov 18 '16 at 17:11

@Tetsujin Hello, sir. I'm not tring to learn to produce animations. I just want to know the principle how the intro video could be played automatically the first time you log in to a Mac. Of course, I know how to create such a video. I just try to archives this on macOS Sierra or OS X El Capitan. – Vincent Nov 18 '16 at 17:15

I don't know how Apple did it, but a common solution to 'one-time only' actions is to check for the presence of a special hidden file in the user's home directory before doing them.
So in this case, you'd have a login script that checks if the file is there. If it is, do nothing. If it's not, play the video, then create the file.
