Instructions
CAUTION: You must establish an ongoing backup plan for your computer and data. In the unlikely event that a problem occurs during the encryption process or drive failure, a backup will be the only mechanism to restore encrypted data. In addition, we strongly recommend storing critical or important files in a separate location from your hard drive.
TIP: We recommend keeping your Mac plugged in during this process, as a power loss could result in the loss of personal data.
2) Click Security & Privacy.
3) In the bottom left-hand corner, click the lock icon.
4) Authenticate using Touch ID.
Alternatively, you may type a username and password with administrative privileges on your Mac. Then, click Unlock.
5) Under the FileVault tab, click Turn On FileVault.
6) Click the radio button next to "Create a recovery key and do not use my iCloud account". Then, click Continue.
7) Document the recovery key and click Continue.
CAUTION: If you're using Jamf to enable FileVault on a TTU-owned computer, you should not copy down the recovery key. If this key is needed, you should contact IT Help Central to retrieve it. If you do store a recovery key, never store it in proximity to the computer (for example, on a sticky note attached to the computer or peripherals, in a draw of the desk where the computer is primarily used, in a laptop's travel bag, etc.).
8) Click Continue.
9) Wait for your Mac to finish the encryption process.
NOTE: The time it takes may vary based on the amount of data saved on the disk and the type of drive being used (for example, SSD).
Outcome
Your Mac has been encrypted using FileVault.
