  2. You will see a window asking you to use the drive to back up with Time Machine. Check the box for Encrypt Backup Disk. After this click on Use as Backup Disk.
  3. If you do not see the above window, click on the Apple icon, and select System Preferences. Click on Time Machine.
  4. Click on Select Backup Disk, and choose your drive.
  5. Finally, check the box for Encrypt Backups (recommended) and click on Use Disk.
