Before you read, copy, or write files to a BitLocker encrypted USB drive, the first thing you need to do is to decrypt the drive on your Mac. However, Microsoft only developed and released BitLocker for the Windows version, so macOS cannot directly decrypt and access BitLocker-encrypted USB drives.
Fortunately, you can use third-party software to decrypt and mount your BitLocker USB drive in read-write mode. iBoysoft BitLocker for Mac provides full features to help you use your BitLocker encrypted drives without any limitations. It can recognize BitLocker-encrypted drives and mount them as any Mac-friendly physical drive.
Step 1: Download and install iBoysoft BitLocker for Mac.
Step 2: Connect your BitLocker USB drive to your Mac.
Step 3: Type in the passcode or 48-digit BitLocker recovery key to unlock your BitLocker-encrypted USB.
After that, your BitLocker encrypted drive will be mounted in read-write mode, then you can read, copy, or write files into the BitLocker-encrypted USB drive on your Mac.
