Understanding FileVault

FileVault is a disk encryption program available on Mac computers. It converts all your data into unreadable code or in other words, encryption.  This, ensures unauthorized individuals can’t read the files on your computer even if they get physical access to your hard drive.. This encryption remains intact until the correct decryption key is provided.

Why Every Mac User Should Consider FileVault

Online privacy and data protection are more critical than ever. While threats like unauthorized access and data breaches lurk around, FileVault acts as your digital shield. It works silently in the background, ensuring your data is safe without affecting your Mac’s performance.

Activating FileVault on Your Mac

  • Starting the Process
    • Click the Apple icon in the top-left corner of your screen.
    • Navigate to ‘System Preferences’.
    • Choose ‘Security & Privacy’.
  • Initiating Encryption
    • Select the ‘FileVault’ tab.
    • Click on the Lock icon located at the bottom right.
    • Enter your Mac’s password for authentication.
    • Click the ‘Turn On FileVault’ button.

Remember, once activated, FileVault will begin encrypting all existing files on your startup disk. Any new files you create henceforth will also be automatically encrypted.

The Crucial Recovery Key

Upon activating FileVault, you’ll receive a recovery key. This key is essential for decrypting your data, especially if you forget your password. Ensure you store this recovery key safely, away from potential threats.

Turning Off FileVault

While FileVault offers exceptional security, there might be times you need to disable it:

  1. Access ‘System Preferences’ again.
  2. Go to ‘Security & Privacy’ and select the ‘FileVault’ tab.
  3. Authenticate by clicking on the Lock icon and entering your password.
  4. Choose ‘Turn Off FileVault’.

While deactivating FileVault is a straightforward process, it’s recommended to keep it on for continuous data protection.

Troubleshooting Common Issues

Sometimes, users might face challenges, such as FileVault taking longer than expected. If you encounter any hitches:

  1. Go to ‘Applications’, then ‘Utilities’, and choose ‘Disk Utility’.
  2. Select your disk and click ‘First Aid > Run’.
  3. If the issue persists, you might need to access the Disk Utility via Recovery Mode or use Terminal commands for further troubleshooting.

Enhancing Your Mac’s Privacy

While FileVault is a formidable security tool, consider complementing it with additional software like MacKeeper. This software ensures broader protection, guarding against threats like malware and spyware.


Your digital security shouldn’t be taken lightly. FileVault offers a user-friendly yet robust way to ensure your Mac’s data remains protected. With the increasing threats in the online realm, tools like FileVault act as essential barriers, keeping your data safe from prying eyes.
