Encrypting everything!

[InsightsIE]

I want to be able to encrypt my entire Macintosh HD with true crypt with the 3 layers of security. Along with that once you decrypt the drive add another layer of protection by using the default login and if you enter it wrong 3 times the hard drive erases securely

Truecrypt doesn't support FDE boot disks on OS X. You'll have to use PGP for that one. PGP offers no plausible deniability or self-destruct features but if your key is long enough and not anything foolish like , oh I dunno, something you'd find in the dictionary, it'll buy you some time.
