Please rethink the NAV Mac UI options that are presented to non-admin users on Mac. As the administrator, I've made deliberate decisions about what elements of NAV I want enabled (ex., turned off "Safe Web"). There is no need to nag every non-admin user constantly that their browser protections aren't on.
Additionally, when a non-admin user is logged-in, sometimes they are presented with an alert (firewall or virus) that they can't act on, since they don't have admin rights. Some of them, they can't cancel either.
