How can I pre-authorize authopen?

Answer 1

I think if you give your app path in the 1st arg:

execl(authopenPath,
      "app path", // <--
      "-stdoutpipe",
      [self.device.devicePath fileSystemRepresentation],
      NULL);

the dialog will show:

"app name requires that you type your password"

Answer 2

The simple truth seems to be that it's not yet possible to do this.

Answer 3

You need to be looking directly at the security framework, introduced in 10.4, I think, and been the main authorization source since 10.5. OSX still works within PAM (like Linux), but /etc/authorization now supersedes this. Apple does have one or two samples of code on how you could pragmatically create a class/entry for someone to authorize themselves against (or preauthorize/be preauthorized like folks who are allowed to print).
