How to open/access Bitlocker encrypted drive on macOS for free?

Updated by Admin to Bitlocker for Mac on June 25th, 2019

Microsoft has not implemented Bitlocker for Mac version, so macOS cannot recognize Bitlocker encrypted drive, so with the help of the third party Bitlocker for Mac tool, Bitlocker is compatible with macOS and Mac OS X.

Is there a Bitlocker for Mac freeware?

The answer is Yes. Dislocker is a free tool which uses FUSE driver to open/access BitLocker encrypted volume on macOS/Linux. Dislocker is a tool to decrypt/unlock BitLocker encrypted volume from Linux or macOS developed by Romain Coltel. Dislocker uses a fuse based mechanism to decrypt the volume 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 experiance for end users to have to open terminal and run a bunch of commands to use their Bitlocker encrypted USB drives.

- Headers for FUSE;
