Normally, Mac computer cannot read a drive protected by Windows BitLocker, because Microsoft has not implemented BitLocker client for Mac OS. If you insert a BitLocker-protected USB flash drive into a Mac computer, you will be prompted the disk you inserted was not readable by this computer. Even if you can open the drive, all you can get is a BitLockerToGo.exe file and a Read Me.url file, as shown in the figure below. All the contents inside the USB flash drive do not show up on Mac.
That does really bother us when we need to use a BitLocker-encrypted USB flash drive on Mac. However, there is no need to worry now. We released the iSumsoft BitLocker Reader for Mac utility that can help you easily access and read BitLocker-protected USB flash drive on Mac. Here are the steps.
