How to open BitLocker encrypted drive on Mac for free?

Updated by Tim to BitLocker for Mac Tips on March 27th, 2020

Microsoft only released BitLocker for Windows version and has not implemented BitLocker for Mac version, so macOS cannot recognize BitLocker encrypted drive. However, with the help of the following solutions, you can open BitLocker encrypted drive on Mac for free.

Option 1: Dislocker

Dislocker is a free BitLocker for Mac software which uses FUSE driver to access BitLocker encrypted drive on macOS/Linux. Dislocker is a free tool to decrypt/unlock BitLocker encrypted drive from Linux or macOS developed by Romain Coltel. Dislocker uses a fuse based mechanism to decrypt the BitLocker encrypted drive and mount it so that the user can access (read or write) the files within the volume.

Dislocker is doing all the hard work because it is a command line program designed to be used by IT professionals to perform data recovery/management, not so much for end users. I think we can agree that it is terrible user experience for end users to have to open terminal and run a bunch of commands to open their BitLocker encrypted drive on Mac.

Tutorial for how to use dislocker on macOS/Mac OS X:

You need:
- Headers for FUSE;
- Headers for PolarSSL;
- A partition encrypted with BitLocker, from Windows Vista, 7, 8 or 10.

For Debian-like:
aptitude install libfuse-dev libpolarssl-dev
For Fedora-like:
yum install fuse-devel polarssl-devel


First thing to do is to cd into the src/ directory. Then, just install Homebrew ( and run the
following command:
$ brew install dislocker.rb
This will install dislocker.

Once installed, see dislocker(1) for details on how to use it, refer to dislocker documentation.

Dislocker is a free command tool, so it is very complex for general users who don't have technical knowledge, but there is a dislocker alternative: M3 BitLocker Loader for Mac, it provides easy-to-use UI makes the operations very simple and easy.

Option 2: Install Windows and Boot Camp
