Turn on and set up FileVault

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.

1. Choose Apple menu () > System Preferences, then click Security & Privacy.
2. Click the FileVault tab.
3. Click , then enter an administrator name and password.
4. 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.

A startup disk is a partition of a drive or a volume that contains a usable operating system. Your startup disk doesn’t have to contain macOS. For example, your Mac can boot directly into Windows if you’re using Boot Camp. It can also boot into Ubuntu or any other operating system supported by your Mac’s hardware.

The following steps can do the fixing: The USB boot drive is attached to the Mac, and the system is rebooted.

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.

* 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.
