This mode allows a Mac to function as an external hard drive when connected to another computer via a Thunderbolt or FireWire cable. The connected computer can then access the Mac’s files as if it were a standard external storage device. This functionality enables direct data transfer between two machines, bypassing network connections or removable media.
Facilitating rapid and efficient file transfers, this method proves invaluable for migrating data to a new machine, troubleshooting software issues, or retrieving files from a non-booting system. Historically, this capability offered significant advantages in speed and reliability compared to alternative transfer methods available at the time. Its continued relevance highlights its utility in specific scenarios where direct access to the file system is required.
