As the amount of personal data stored on our Macs continues to grow, it becomes increasingly important to protect that data from prying eyes.
Fortunately, Macs come with a built-in encryption tool called FileVault that allows you to encrypt your entire hard drive, ensuring that no one can access your data without your password.
If you want to know how to use FileVault to encrypt your Mac simply go to System Preferences, click on Security & Privacy, and then select the FileVault tab. From there, you can turn on encryption and set a password to lock your Mac's disk.
In this article, I'll walk you through the entire process of setting up FileVault to encrypt your Mac and how it works to protect all your data.
How to Use FileVault to Encrypt Your Mac
What is FileVault?
FileVault is a built-in encryption tool on macOS that allows you to encrypt your entire hard drive, including your operating system, applications, and data.
When FileVault is enabled, your Mac requires a password to boot up, and all data on the hard drive is encrypted using 128-bit AES encryption and a 256-bit key.
This makes it virtually impossible for anyone to access your data without your password.
Enabling FileVault on your Mac
Enabling FileVault is a straightforward process, and it only takes a few minutes to complete. Here's how to do it:
- Click on the Apple menu on the top left corner of your screen and select System Preferences.
- Click on Security & Privacy.
- Click on the FileVault tab.
- Click on the lock icon on the bottom left corner of the window and enter your administrator username and password to unlock the settings.
- Click on Turn On FileVault.
How to create a Recovery Key for FileVault?
In the event that you forget your login password, the FileVault recovery key is the only way to unlock your encrypted startup disk and access your files.
Here's how to create a recovery key for FileVault on your Mac:
- Once you go ahead and turn on FileVault, you will be prompted to choose whether you want to create a recovery key or use your iCloud account to unlock your disk.
- If you choose to create a recovery key, make sure to save it in a safe place as you will need it to access your data if you forget your password.
- Once you have chosen your preferred method of unlocking your disk, click on Continue.
- You will be prompted to restart your Mac. Click on Restart.
- After your Mac restarts, the encryption process will begin. This may take several hours, depending on the size of your hard drive and the speed of your Mac.
- Once the encryption process is complete, you will be prompted to log in with your password, which will now be required to unlock your disk.
If you forget your login password, you can use the recovery key to unlock the encrypted startup disk and reset your password.
To do so, restart your Mac and hold down the Option key as it starts up. You will be prompted to enter your recovery key, which will allow you to unlock the encrypted startup disk and access your files.
How to use FileVault on your Mac
Once you've enabled FileVault, your Mac will automatically encrypt all new data as it's added to the hard drive.
FileVault protects all the data on your startup disk, including your user data (such as your documents, photos, and music), system files, and applications.
It does not protect data that is stored outside of your startup disk (such as data stored on an external hard drive or in the cloud.
Therefore, it's important to ensure that you also protect any external storage devices or cloud accounts that contain sensitive data.
You can continue to use your Mac as normal, but there are a few things to keep in mind:
- If you forget your password or lose your recovery key, you won't be able to access your data. It's essential to keep your password and recovery key in a safe place.
- If you need to sell or give away your Mac, you should turn off FileVault to ensure that the new owner can access the computer.
- To do this, open System Preferences, click on Security & Privacy, click on the FileVault tab, and click on Restart and Turn Off FileVault Encryption.
- If you need to give someone temporary access to your Mac, you can create a guest account that doesn't have access to your encrypted data.
- To do this, open System Preferences, click on Users & Groups, click on the lock icon in the bottom left corner of the window, and enter your administrator password. Then click on Guest User and select Allow guests to log in to this computer.

What are the benefits of using FileVault to encrypt your Mac
FileVault encrypts all of the data on your startup disk, which makes it much more difficult for someone to access your data without your permission.
If your Mac is stolen, the thief won't be able to access your data without your password (or recovery key).
FileVault helps you comply with data protection regulations that require encryption of sensitive data.
FileVault is easy to set up and use, and it runs in the background, so you don't need to do anything extra to ensure your data is protected.
Troubleshooting FileVault Not Working on Mac
What to do if I forgot my FileVault recovery key?
If you have forgotten your FileVault recovery key on a Mac, you can try the following steps:
- If you enabled iCloud Keychain, your FileVault recovery key may be stored there.
- You can check by going to System Preferences > Apple ID > iCloud > Keychain.
- If you have multiple Macs that use the same iCloud account, your recovery key may be stored on one of them.
- You can check by going to System Preferences > Security & Privacy > FileVault and clicking on the "Show Hint" button. If the hint refers to another Mac, that Mac may have the recovery key stored.
- If your Mac is issued by your employer or school, they may have stored the recovery key for you.
- You can check with your IT department or system administrator to see if they can provide the key.
- If you created a FileVault recovery key and stored it on a USB drive, you can use that key to unlock your Mac.
- Connect the USB drive to your Mac, then restart your Mac and hold down the Option key. Select the recovery key on the USB drive to unlock your Mac.
- If you have enabled FileVault recovery with your Apple ID, you can use it to reset your password.
- Restart your Mac and enter the wrong password three times. Your Mac will prompt you to reset your password using your Apple ID.
