A drive (e.g. USB flash drive) encrypted with BitLocker requires to be unlocked before you can use it on a computer, including Mac. When you insert a BitLocker drive to a Windows computer, Windows automatically pops up a prompt to allow you to unlock the drive. However, the situation is quite different on macOS. When you insert a BitLocker drive to your Mac, the drive is not readable and macOS does not provide any way to unlock it.
