Disk Encryption For Mac Os X
FileVault is one of those Mac features that you know is there but are never really sure what it’s there for. Apple has never really made a big song and dance about how the feature protects your data or why you should bother with it, so we’re going to do it instead.
This won’t be a literal song and dance, unfortunately, (we don’t have the natural rhythm) but we will tell you all you need to know about FileVault, as well as how and why you should use it. But feel free to sing the words as you read them and dance along at the same time.
Okay, let’s get into it.

FileVault is available on all new MacOS and Mac OS X versions and Mac computers. For some history, FileVault debuted in Mac OS X 10.3, and the earlier versions of FileVault actually only locked down and encrypted the user home directory, whereas modern versions of FileVault encrypt.
What is FileVault?
FileVault is macOS’s built-in disk encryption feature. It's designed to encrypt your Mac's hard drive and all of the files located on the drive using 128-bit AES encryption with a 256-bit key.
Once FileVault is enabled on your Mac, all existing data will be encrypted. From then on, any new and changed data will be automatically locked down and password protected on boot to prevent unauthorized access.
FileVault was originally introduced to Mac back in 2003 on OS X 10.3 Panther. But to say it wasn’t very good would be an understatement. It was terrible. The functionality was poor, the implementation was shoddy, and only the home directory could be encrypted.
Thankfully, 2003 was a long time ago and now, with FileVault 2, you can expect full-disk encryption and the ability to use the Find My Mac feature to wipe your drive remotely if ever your system falls into suspect hands.
Should I use FileVault?
Yes, is the short answer.
If you’re concerned about the privacy of your files and user data, and your computer contains information that shouldn’t be seen without authorized access, you should absolutely use FileVault disk encryption.
The feature is particularly good if you’re a MacBook user that regularly takes your laptop on the move where there’s a greater chance of it becoming lost or misplaced.
FileVault offers peace of mind and that counts for a lot. There are, however, reasons why you might not want to bother with the feature.
First of all, FileVault enforces a password. If you struggle to remember passwords (it’s well worth using a password manager if you do) or prefer using your Mac without one, you might consider FileVault to be more effort than it’s worth.
Secondly, FileVault encryption is backed into the CPU which can affect performance. If you own a newer SSD-equipped Mac you’re unlikely to notice the difference, but in older Macs with HDDs performance can take a significant hit — enough for you to consider using your computer without encryption.
How to check if FileVault is enabled?
In systems running OS X Yosemite 10.10 and newer, Apple encourages you to turn on FileVault 2 during setup. So, if you’re using a newer Mac, there’s every chance that your files are already being encrypted.
Here’s how to check:
- Click on the Apple menu and select System Preferences.
- Select Privacy & Security.
- Click on the FileVault tab and the status will be displayed.
Before you turn on FileVault, be aware that the initial encryption process can take hours. However, it does run in the background so you can continue using your Mac as normal, albeit not at peak levels of performance.
Also, FileVault encrypts the entire disk. Any additional users will need to be enabled so that they can unlock the disk by entering their password.

How to turn on FileVault disk encryption
- Click on the Apple menu and select System Preferences.
- Select Privacy & Security.
- Click on the FileVault tab, then click the lock in the bottom left corner of the window.
- Enter your administrator name and password and click Unlock.
- Click Turn On FileVault.
- Choose whether you want to link your iCloud account to FileVault to unlock the disk and reset your password or create a recovery key and click Continue.
- Click Restart to reboot your Mac and begin the encryption process.
Choosing a FileVault Recovery Key
The FileVault recovery key deserves special mention here. If you choose this option over linking your iCloud account, it’s critical that you make a note of the recovery key and keep it in a safe place that’s not on your hard drive. Losing the recovery key makes your data unrecoverable so it’s worth writing it down and storing it in a safe place, as well as entering it into a password manager.
How do I turn off FileVault?
Once your disk has been encrypted you can turn off FileVault at any time. You might decide to do this if you find that the feature is too resource-heavy or this particular level of security isn’t for you.
- Click on the Apple menu and select System Preferences.
- Select Privacy & Security.
- Click on the FileVault tab, then click the lock in the bottom left corner of the window.
- Enter your administrator name and password.
- Click Turn Off FileVault.
Disabling FileVault starts the process of decrypting all of your files. This runs in the background but, like encryption, is a lengthy process.
How do I keep online and offline activity private?
FileVault’s capabilities only extend as far as user data and file encryption. Other things you do on your Mac like web browsing, chatting via messaging apps, downloading software, and using files locally are not private.

Of course, in the event that your Mac is lost, for anyone to see your online and local activity they’d need to enter the admin password first. But if you share computer access and want to keep your activity private, the best option is to use an app like CleanMyMac X.

Follow these steps to encrypt Macs.
Before users can start:
- You must install the Sophos Central agent software on the endpoints.
- You must configure and turn on a Device Encryption policy in .
- Users must log on to their endpoints. They must be connected to and synchronized with . Note that remote logon is not supported.
These instructions tell you what the users see and what they need to do.
- Enter their login password after starting their Mac.
- Click either Encrypt to start the encryption of their system disk or Postpone to start the process later.
When users enter their login password and click Encrypt, the recovery key is stored locally in the keychain and .
All existing users of an endpoint are added to FileVault automatically.
On endpoints running macOS 10.12 or earlier, each user needs to log in separately to be added to FileVault.
When the system disk is encrypted, the internal data volumes are automatically encrypted. Encrypted disks are automatically unlocked when the computer starts.
