To check the progress of FileVault encryption, just look at the FileVault tab of Security & Privacy Preferences. That’s important to note - FileVault will not encrypt a MacBook’s disk when the computer is asleep or on battery power. Once FileVault is enabled, it encrypts the startup disk as you use the Mac but only when the computer is awake and connected to AC power. This is important to remember! What Happens Once FileVault Is Enabled? Instead, it should be saved somewhere else safe, like printed and stored in a personal safe or safety deposit box or stored in the Notes app on an iPhone or iPad in a password-protected note.Īpple makes a point of letting you know that if you lose your account password and the FileVault recover key, you will not be able to log in to the Mac or access the data on the startup disk.

What Macs Can Use FileVault Encryption?įileVault is actually a feature of Mac OS X and macOS, not a hardware function. Fifty supercomputers that could check a billion billion (10 18) AES keys per second (if such a device could ever be made) would, in theory, require about 3×10 51 years to exhaust the 256-bit key space.” It is very unlikely that a typical laptop thief could break FileVault encryption before the end of the universe, by which time the information stored on the disk would be quite irrelevant anyway. That method is quite secure a Wikipedia search showed that “Breaking a symmetric 256-bit key by brute force requires 2 128times more computational power than a 128-bit key. How Good Is FileVault Encryption?įileVault uses an encryption method known as “XTS-AES-128 encryption with a 256-bit key” to encode the information on a disk. That “key” can be a password or some biometric means of identification. Encrypting the disk means that the information stored on it is encoded using an algorithm (also known as a cipher) that scrambles the data and makes it readable only by someone holding a decryption key.

In other words, if someone stole a Mac, removed the unencrypted startup disk, and connected it to another computer with the proper cable, they would have access to read all of the files on that computer. When a Mac stores information on a hard disk drive (HDD) or solid-state drive (SSD), it is generally written in a format that can be easily read by anyone with a computer.

The current implementation of FileVault is known as FileVault 2 - for the purpose of brevity in this post, it will just be called FileVault. In this Mac 101 article, we’ll take a detailed look at FileVault, how it works, things to watch out for when using it, and why owners of Mac laptops should consider using FileVault.
