I think you may have missed part of the title.  The author isn&#x27;t aiming only for security, but also privacy.  Disabling calendar &amp; spotlight seem to be aimed at privacy, not security.  I&#x27;m not sure I follow you when you claim the author has disabled &quot;applications like...finder&quot;--I didn&#x27;t get that from the article.  It sounds like the author really doesn&#x27;t like apps that phone home to Apple, though.<p>It might have been nice for the author to state explicitly which steps are aimed at security and which for privacy.
