This process involves starting a Mac computer in a specific state that allows it to function as an external hard drive for another Mac. It connects the two machines via a Thunderbolt or FireWire cable, enabling direct access to the first Mac’s files and operating system. This connection facilitates data transfer, operating system reinstallation, or troubleshooting.
Facilitating efficient file transfer, seamless operating system migration, and effective troubleshooting, this approach provides a valuable tool for users. It can significantly reduce the time needed for large file transfers compared to traditional methods like networks or external drives. Further, it streamlines the process of reinstalling macOS or migrating data to a new machine. Introduced alongside FireWire technology, it has remained a valuable feature for Mac users over the years.
