Turn on and set up FileVault
How to use OS X's FileVault 2 to encrypt files and folders. Update your operating system by clicking on the 'Software Update button.' For more help upgrading to the latest Mac OS X, see our sister site. Make sure you have OS X Recovery downloaded. This is another Mac app that comes with OS. Whole-disk encryption is an effective line of defense for a single device, but it doesn't help when you need to share encrypted data. You can use a Virtual Private Network, or VPN, to encrypt. Step 1: Open the Terminal on you Mac and then type in the following command: openssl aes-256-cbc -in /Desktop/Photo.jpg -out /Desktop/Encrypted.file. 'in /Desktop/Photo.jpg' is where the file you want to encrypt is and 'out /Desktop/Encrypted.file' represents the location where the file will be saved. COMMAND LINE VERSION:. For Windows, Linux AND mac OS Users.: Install JRE (JAVA RUNTIME ENVIRONMENT) MIN VERSION: 1.1.0 Launch. GUI VERSION: Windows: Double-click OR cmd - 'java -jar XEnCrypT.exe'. Mac OS: Terminal - 'java -jar XEnCrypT.exe'. Linux: Terminal - 'java -jar XEnCrypT.exe'. COMMAND LINE VERSION.
FileVault 2 is available in OS X Lion or later. When FileVault is turned on, your Mac always requires that you log in with your account password.
- Choose Apple menu () > System Preferences, then click Security & Privacy.
- Click the FileVault tab.
- Click , then enter an administrator name and password.
- Click Turn On FileVault.
If other users have accounts on your Mac, you might see a message that each user must type in their password before they will be able to unlock the disk. For each user, click the Enable User button and enter the user's password. User accounts that you add after turning on FileVault are automatically enabled.
Choose how you want to be able to unlock your disk and reset your password, in case you ever forget your password:
- If you're using OS X Yosemite or later, you can choose to use your iCloud account to unlock your disk and reset your password.*
- If you're using OS X Mavericks, you can choose to store a FileVault recovery key with Apple by providing the questions and answers to three security questions. Choose answers that you're sure to remember.*
- If you don't want to use iCloud FileVault recovery, you can create a local recovery key. Keep the letters and numbers of the key somewhere safe—other than on your encrypted startup disk.
If you lose both your account password and your FileVault recovery key, you won't be able to log in to your Mac or access the data on your startup disk.
Encryption occurs in the background as you use your Mac, and only while your Mac is awake and plugged in to AC power. You can check progress in the FileVault section of Security & Privacy preferences. Any new files that you create are automatically encrypted as they are saved to your startup disk.
When FileVault setup is complete and you restart your Mac, you will use your account password to unlock your disk and allow your Mac to finish starting up. FileVault requires that you log in every time your Mac starts up, and no account is permitted to log in automatically.
Reset your password or change your FileVault recovery key
If you forget your account password or it doesn't work, you might be able to reset your password.
If you want to change the recovery key used to encrypt your startup disk, turn off FileVault in Security & Privacy preferences. You can then turn it on again to generate a new key and disable all older keys.
Turn off FileVault
If you no longer want to encrypt your startup disk, you can turn off FileVault:
- Choose Apple menu > System Preferences, then click Security & Privacy.
- Click the FileVault tab.
- Click , then enter an administrator name and password.
- Click Turn Off FileVault.
Decryption occurs in the background as you use your Mac, and only while your Mac is awake and plugged in to AC power. You can check progress in the FileVault section of Security & Privacy preferences.

- If you're using FileVault in Mac OS X Snow Leopard, you can upgrade to FileVault 2 by upgrading to OS X Lion or later. After upgrading OS X, open FileVault preferences and follow the onscreen instructions to upgrade FileVault.
- RAID partitions or non-standard Boot Camp partitions on the startup drive might prevent OS X from installing a local Recovery System. Without a Recovery System, FileVault won't encrypt your startup drive. Learn more.
* If you store your recovery key with Apple or your iCloud account, there's no guarantee that Apple will be able to give you the key if you lose or forget it. Not all languages and regions are serviced by AppleCare or iCloud, and not all AppleCare-serviced regions offer support in every language. If you set up your Mac for a language that AppleCare doesn't support, then turn on FileVault and store your key with Apple (OS X Mavericks only), your security questions and answers could be in a language that AppleCare doesn't support.
Let's say you want to store sensitive files on a flash drive, or maybe send it out via email, or whatever the case may be. You'll probably want to encrypt that file.
