You are misrepresenting the facts. Each installation of any app under OS
X requires specific approval and entry of an admin password -- even if
the admin is logged in as the current user! That is very different from
the vast majority of XP machines where malicious code can install and
execute without approval if the admin is logged in.

For someone who claims to do "software development professionally", you
seem to have trouble understanding that important distinction between
the two operating systems.
