How to Open Encrypted USB Drive on Mac

Jun 25. Posted by to Windows Topic

Encrypting a USB drive so only authorized users have access is always a good idea when dealing with sensitive or private information. But what happens when you want to access that same data on a Mac and you don't have the ability to use the same software to decrypt and unlock the drive? BitLocker for Windows poses exactly that kind of problem because it only works on Windows computers. So, if you're using a USB drive encrypted by BitLocker on a Mac, there's really no direct way to access the content in encrypted drive on Mac. Fortunately, there's a workaround for it, which is what this article outlines.

Although BitLocker is not natively supported on Mac machines, there are several third-party tools you can use to gain access to a USB drive that has been encrypted with it. One such utility is M3 BitLocker Loader for Mac. The software is compatible with Mac OS X 10.6 and higher versions, and can unlock a wide range of storage devices like USB drives, external hard drives, SD cards and more. You can also use it to encrypt a drive, but that involves formatting the drive with a Windows-friendly file system like NTFS or FAT32.

How to Open Encrypted USB on Mac with M3 BitLocker Loader

M3 BitLocker Loader for Mac essentially provides the environment in which to access drives or other devices that have been encrypted with AES in CBC mode using BitLocker, which uses a 128-bit or 256-bit encryption key.

To open an encrypted USB on a Mac, follow the steps described below:

Step 1: As a first step, install the application on your Mac.

Step 2: Launch the program and insert the USB drive into the Mac. To make sure that you're able to access the drive, make sure that it has not been corrupted. If it has, you may need to use a recovery program to get it back to a working state.

Step 3: In the M3 Loader window, you may see an error message after inserting the drive. Simply click on the Ignore option if that happens. This is merely a format conflict between the drive and macOS, but since you're using a third-party application to access the drive, you can choose to ignore the alert.

Step 4: Click on the drive in the software window and then on Open. When prompted for the password, enter it and click Unlock.

Step 5: Once the drive has been decrypted, you can access the folders and files inside just as if you were working inside the native Finder app in Mac.

Please note that the drive can not be unlocked unless you have the password. This is not a password utility. It merely allows you to mount the drive virtually and decrypt it so you can access the contents of the drive on a Mac.

 

Remove BitLocker Encryption from USB on Mac

If you forgot the open password of encrypted USB driver or just want to remove protection from the USB so you can use it more freely on Mac, then it is advised to remove the password from encrypted USB. Fortunately, this can be done on Mac for free.

Step 1: After taking a backup of the data on your USB drive on a Windows PC, insert it into the Mac.

Step 2: Open the Disk Utility application from the Applications > Utilities folder.

Step 3: In the left panel, look for the encrypted drive and select it.

Step 4: From the toolbar at the top, select the Erase button. The drive will be erased and the encryption removed. You can then choose to format the drive, but that's beyond the scope of this article.
