Apple FileVault 2, a BitLocker Mac equivalent, is used to encrypt internal hard drives on Mac, while many third-party open-source apps can be installed to encrypt external storage media including HDDs, SSDs, SD cards, and USB flash drives.

Find some popular BitLocker equivalents for Mac:

  1. VeraCrypt
  2. TrueCrypt
  3. AES Crypt
  4. File Lock PEA
  5. Encrypto
  6. Axcrypt
  7. Ciphershed

Are Macs Encrypted by Default?

It is a question without a simple yes or no answer. It all depends on what Mac model you are talking about.

For older Mac models before 2018, they are not encrypted by default. You need to turn on FileVault manually and then it starts to encrypt and decrypt your Mac hard drive.

However, for newer Macs with a T2 Security Chip and an Apple Silicon Chip, the built-in on-the-fly encryption encrypts Mac's SSD without user setup. In other words, those Macs are encrypted by default and the encryption cannot be turned on or off by an end user.

Also, on the T2 or M3, M2, and M1 Macs, you can turn on FileVault to add another layer of protection.

How to make a USB drive BitLocker encrypted on Mac?

You can't encrypt a USB drive on Mac via BitLocker unless you employ a reliable third-party BitLocker for Mac tool. It uses the same BitLocker Drive Encryption algorithm as Windows to encrypt hard drives and other portable disks.

After the encryption process is finished, you can use the BitLocker-encrypted USB drive on Windows that supports BitLocker (Windows 10 Pro, Education, and Enterprise Edition).

How to turn off BitLocker encryption from a USB drive on Mac?

When you decided that BitLocker encryption is no longer needed for your USB drive, you can disable it and decrypt your data easily with a Windows PC.

But if you want to remove BitLocker encryption on a Mac, the only way is to format the disk using Disk Utility. But this method will erase all your files and make them unrecoverable. Read below to see how to format a BitLocker-encrypted drive on Mac.

How to format a BitLocker-encrypted USB drive on Mac?

Formatting a Bitlocker-enabled USB drive on Mac will return you a blank disk. Before doing so, you should use a BitLocker for Mac app or a Windows computer to back up your important files first.

Just like formatting any other Mac-friendly drive, you open Disk Utility and erase the BitLocker-encrypted drive. Or click "Initialize" when the error message pops up, and you will be led to the Disk Utility window to wipe the disk and give it a workable file system as well.
