![]() ![]() Turning encryption onĮnabling FV2 is a straight-forward process. Note: Since the original incarnation of FV (referred to as legacy FileVault) has been superseded by FV2, all discussions moving forward will pertain to FileVault 2 exclusively. ![]() Miyagi taught Daniel-san Karate through lessons that simplified the basics of defense, Apple has taken a similar approach with regards to enabling/disabling the security protection we’re discussing here today. “Wax on, wax off”Īs the martial arts master himself, Mr. We’ll dive more into FV2’s features and how it works a little later. FV2 is the standard encryption technology available through all iterations of OS X and macOS since then. ![]() In 2007 however, with the release of OS X “Lion” (10.7), the encryption technology developed by Apple was redesigned with additional features and named FileVault 2 (FV2). ![]() It enabled encryption by using Apple’s sparse disk image - similar to a DMG file but encrypted - to contain the contents of the user’s volume, including their Desktop and Documents directories, among others. When enabled, FileVault would encrypt the contents of a user’s home volume only by utilizing the user’s credentials as the method to lock and unlock the volume when the user was logged off or successfully authenticated. Apple released OS X “Panther”, or version 10.3, which introduced FileVault (FV), the technology that provides data encryption in Mac. And the benefits to enabling FV on you Macīefore we delve into the points above, let’s take a little trip to 2003.This is to say that the term“encryption” itself can expand to include a great many possibilities and variables that can affect them further, like salting a hash value or writing your own cipher - booth of which are advanced cryptographic topics that are well beyond the scope of this blog. Depending on your experience level, encryption may be as simple as marking a file or folder hidden within a directory to password protecting a ZIP file with a sixty-four-character password filled with variable key spaces to keep password cracking software at bay for a millennia. Encryption can mean many things to many people. ![]()
