Could it not ask the user? My Apple regularly asks for decisions of

I continue to believe that few users would grant an email message
access to both the Internet and the Address Book when they are asked
those two questions, provided that the user had not been conditioned to
clicking "YES" in order to get any work done at all.

Yes... and it isn't that the users are stupid or ignorant. Most of the time it's /really hard/ to be 100% sure, unambiguously, what the pop-up dialogue is talking about. This is for several reasons...

- Language.  It's hard to write a clear and unambiguous
  message, and since these are written by programmers they
  usually aren't even grammatically correct, never mind clear
  and unambiguous.

- Context.  The user often has multiple things going on, and
  often acts faster than the computer's stupid, slow, laggy,
  ugly GUI... now what did I do that caused this pop-up?  Was
  it my last click, or the other window that finally popped up
  from the link I clicked 2 minutes ago and which I had almost
  forgotten about?

- User mental "state".  The pop-up may ask for permission to use
  a previously entered password, but the user can't remember what
  they previously entered... was that one of my throwaway,
  non-secure passwords, or was it the PIN for my bank account?

These uncertainties cause stress.  After stressing about it for
a while the user clicks one choice only to find later that that
was the wrong one, increasing the stress level even more the
next time.  They are likely to soon give up, but even if they do
persevere in paying attention and trying to make the right choices,
the percentage of errors is going to be very high, and since a single
error can critically compromise security this means it's basically
hopeless.
