BitLocker is a Windows security feature that encrypts entire drives to protect data from theft or exposure. It is included in all Windows Pro versions, starting with Windows Vista. It is not included in Windows Home.
BitLocker encrypts the entire drive to make data inaccessible without a decryption key. This recovery key is a unique 48-digit number that is required to unlock the drive. If the drive is connected to a different device, the user must provide the key to access the data. In addition to the key, the drive can also be protected with a password, which can be used along with the recovery key.
When using GetDataBack on a BitLocker-encrypted drive, it sees the drive in its encrypted state when you access it as a physical drive. Only after unlocking the drive by entering the password or recovery key is the decrypted drive accessible as a logical volume (e.g., E:) and can be scanned by GetDataBack.
We will show how to recover data from a BitLocker-encrypted drive using an 8 GB USB drive as an example. That USB drive is no longer accessible, and Windows offers to format it, which we better not do.

I also see methods for creating a bootable USB using Terminal and DiskMaker X. For system requirements, I have found several lists of supported Mac models. For installation guides, there are results for installing on external drives and older Macs. I'll open some of these pages to gather more detailed information. results provide several methods for downloading macOS Sierra DMG files: using iBoysoft DiskGeeker, GitHub repositories, and direct links from Apple's servers.
