Macs are not invulnerable, but 20-to-30 minutes is an eternity in the world of hackers, and the typical Mac user is in a much safer environment than a Windows user.

Not really.  I've hammered away for days at a server before gaining access to it.

I think the longest it's taken me to crack one was a couple weeks.
