Very nice software and easy to use, was able to help my brother remotely over video call, to open his external hard disk which encrypted with BitLocker.

Mike, 2021-01-28

I tried another tool which works for me but isn't quite as convenient as your tool "M3 Bitlocker Loader for Mac v6.2".

Massimo, 2020-11-26

Yesterday I tried HasleoBitLockerAnywhere but this tool, strange, it unlock the disk but the disk works only in the Finder, while in another filing tools like pathFinder, ForkLift etc. it doesn't permit to write files. Your utility "M3 Bitlocker Loader for Mac v6.0" works very well compared to the other.
