I have a USB flash drive encrypted with BitLocker Drive Encryption, which stores some important files. Recently I bought a Mac computer, I need to access this USB drive in my Mac computer, and when I connect it to my Mac, my Mac doesn't seem to be able to access it. After I got back to Windows, I found out that this drive was using exFAT, and is that why Mac can't access it?
The exFAT file system and BitLocker are effective tools for Windows users to store and protect data. When formatting a large USB drive, many users may not notice that Windows defaults to the exFAT file system. While macOS supports exFAT drives natively, it cannot access a BitLocker-encrypted exFAT drive because macOS does not support BitLocker drive encryption. This explains why macOS cannot access BitLocker-encrypted exFAT drives. So, is there a way to access such drives on a Mac? The answer is yes - we recommend Hasleo BitLocker Anywhere For Mac.
