FileVault 2 - Disk encryption
Like Microsoft's BitLocker Drive Encryption for their Windows OS, Apple has also developed their native drive encryption feature - FileVault 2 (FileVault full-disk encryption). This best BitLocker alternative for macOS utility can prevent unauthorized access from your disk with an encryption key.
FileVault 2 enables almost all data, including the temporary files, on a drive to be fully encrypted. But there are also some differences between FileVault 2 and BitLocker, like the algorithms for data encryption.
How to use FileVault 2 to encrypt Mac data
FileVault has been built into Mac OS X Lion and later. Once the FileVault is turned on, your Mac will always require your account password when logging into your Mac.
To set up FileVault 2, you must have an admin account.
- Step 1: Click the Apple icon and select System Preferences.
- Step 2: Choose Security & Privacy > FileVault.
- Step 3: Click the lock on the left bottom corner of the pane and type the admin account if needed.
- Step 4: Click Turn On FileVault.

- Step 5: Select the "Create a local recovery key..." option and write down the recovery key to some other place. Then, click Continue.
Or, you can select your iCloud account as your recovery option (For OS X 10.10 Yosemite or later).
The encryption process will take some time. You can adhere to other work with your Mac during the period. Once it finishes, restart your Mac. The startup disk will be encrypted during startup.
2. Disk Utility - Folder or drive encryption
Taking similar encryption algorithms like that of FileVault's, Disk Utility can also work as a folder or drive encryption tool for Mac users. It's also a BitLocker alternative for macOS.
How to use Disk Utility to encrypt a folder:
Usually, there are two types of folder encryptions: 128-bit AES encryption and 256-bit AES encryption. The latter will take more time to encrypt a folder but bring a higher level of security when compared to the former one.
- Step 1: Open Disk Utility on your Mac.
- Step 2: Select File > New Image > Image from Folder from the Apple menu bar

- Step 7: Type the required information on the pane and click Save.
Then, waiting for the folder to be encrypted and click Done.
How to use Disk Utility to encrypt an external hard drive:
If you have a new external hard drive and will use it to store important data, you can format the disk to APFS (Encrypted) or Mac OS Extended (Journaled, Encrypted). That will protect your data via encrypting the file system (APFS) or the data itself (HFS+).
You should know that formatting a drive will erase all content on it. If you have data on the drive, please back it up in advance.
- Step 1: Connect the drive to your Mac and open Disk Utility.
- Step 2: Select the drive and click Erase.
