I had to use the locked USB on my Mac. But it does not recognized. WHAT A $#*!! I SEARCH ONLINE AND FOUND BitLocker Genius for Mac. Download and install. Finally my USB is displayed on the MAC with the password to enter. At first I thought it was no need to password. But the support team told me password or recovery key is needed! So, friends, remember, no password or recovery key, you will not unlock a BitLocker USB on Mac! So lucky I did have both!
