How can I gain access to the Windows 10 BitLocker encrypted drive on Mac OSX?
By default, we couldn't open, read and write a BitLocker drive on Mac. But take it easy, the BitLocker Genius tool is a really simple and user-friendly tool that can help you get access to the BitLocker drive without any data loss.

When you meet "The disk you inserted was not readable by this computer" error, you can click on Ignore button. I'm also a user that know little about computer. But I insert the drive to Mac and type my password then that drive is able to work normally.

Besides, you can unlock the BitLocker encrypted drive on Mac using a recovery key as well.
