- Shut down the first computer and leave the second computer on.
- Connect the two computers using a 6-pin to 6-pin FireWire cable. (If both computers have higher-speed FireWire 800 ports in addition to the standard FireWire 400 ports, you can use a 9-pin to 9-pin cable with the FireWire 800 ports to transfer data at higher speeds.)
- Start up the first computer while holding down the T key.
A disk icon for the first computer appears on the desktop on the second computer. Drag files to and from the disk to transfer them.- When you finish, eject the first computer's disk by dragging its icon to the Trash.
- Push the power button on the first computer to shut it down and disconnect the FireWire cable.
