How to Read BitLocker Drive on macOS Ventura (Including M1 & M2 Mac)

I have a MacBook Air 2020 with Apple M1 chip. Recently, I upgraded the OS from Monterey to the latest Ventura (13.0), which is great and like the new interface very much.

However, When I plugged in a BitLocker encrypted external drive into my Mac, it says ‘The disk you attached was not readable by this computer’.

I know Ventura has a lot of improvements over Monterey, but never it expected such a problem as it is quite common to encrypt a portable drive to protect the data. Why this happened and how could you read a BitLocker drive on Mac Ventura? This is the issue we are going to solve in the article.

What is BitLocker Encryption?

BitLocker is a full disk encryption feature included with Windows Vista and later. It is designed to protect data by providing encryption for entire volumes. By default, BitLocker uses the AES encryption algorithm with a 128-bit key. BitLocker can also use other encryption algorithms, such as AES 256-bit encryption.

BitLocker encrypts the entire drive, including the system files, user data, and free space. BitLocker does not encrypt the drive’s boot sector, which is why it is important to use a strong password for the computer’s account.

When BitLocker is enabled, a user must enter a password or use a smart card to unlock the drive and access the data. BitLocker also supports the use of a recovery key, which is a backup key that can be used to unlock the drive if the primary key is lost or forgotten.

BitLocker is a valuable security feature, but there are some potential drawbacks. For example, if a user forgets their password or recovery key, they will not be able to access the data on the drive. Additionally, BitLocker can cause problems if the computer’s BIOS is not compatible.

Is BitLocker Compatible with Mac?

Unfortunately, BitLocker is not compatible with Mac by default.

BitLocker is a popular drive encryption feature used by Microsoft Windows. Apple’s macOS doesn’t have native support for BitLocker. Instead, macOS uses File Vault for disk encryption.

To access a BitLocker Encrypted drive on Mac, you have to use third-party apps to decrypt BitLocker drive so you can read or write BitLocker drive on Mac.

How to Read BitLocker Drive on Mac (Including M1 & M2)

Although Mac does not support BitLocker by default, there are still direct and indirect workarounds to help you read or write a BitLocker drive on Mac. Generally, there are three methods available currently.

Method 1: Access BitLocker Drive on Mac in Windows Virtual Machine

Running Windows on Mac is a common scenario in our life as some of the apps only work in Windows environment. If you had a Windows virtual machine on your Mac, then this is the simplest method to unlock a BitLocker encrypted drive on Mac. Simply launch Windows on Mac and attach the drive. You will be able to read or write the BitLocker drive in Windows virtual machine.

If you didn’t set up a virtual machine on your Mac yet, you can do this with Boot Camp Assistant (for Intel Mac) or Parallels Desktop (for M1 and M2 Mac). The former is a free app that comes with macOS. The later is a premium and dedicated app for running Windows OS on Mac, including Windows 11, Windows 10 and Window 7.

Method 3: Disable BitLocker Drive in a PC

BitLocker is a security feature in Windows that allows you to encrypt a disk. This means that if someone tries to access the drive, they will not be able to read the data unless they have the correct password.

However, there are a few reasons why you might want to disable BitLocker. Maybe you no longer need the extra security, or you need to access your hard drive from another computer that does not support BitLocker. Whatever the reason, here is how you can disable BitLocker in Windows PC.

1. Connect the password protected BitLocker drive to a Windows PC.

2.  Open File Explorer and double click the drive name.

Disk Utility is a built-in tool that can be used to encrypt your hard drive, and it’s relatively easy to use. However, it doesn’t offer the same level of security as FileVault, so it’s not the best choice if you’re looking for maximum protection.

DiskCryptor is a third-party tool that offers full-disk encryption, and it’s relatively easy to use. However, it’s not as well-known as FileVault, so it may not be the best choice if you’re looking for maximum security.
