How to encrypt your Mac with FileVault 2, and why you absolutely should

Glenn Fleishman | Feb. 6, 2015
Apple's first pass at built-in encryption was, frankly, terrible. The original FileVault, introduced with 10.3 Panther in 2003, only encrypted a user's home directory, and had a number of functional and implementation problems. FileVault 2 appeared in 2011 with 10.7 Lion, and had almost nothing to do with the original except the name.

FileVault 2 can make nations quake, apparently, but it's just a bit of good information hygiene, letting you make choices about the degree of vulnerability you want to tolerate for your locally stored data and any software or stored passwords for services in your accounts. With it off, you're not risking everything, but with it on, you have a high degree of assurance about who can access what.
