How to Transfer Your Files from an Old Mac to a New Mac
To transfer files from an old Mac to a new one, you’ll need a six pin to six pin fire wire cable.
Connect each end of the cable to a fire wire port on both the new and old computers.
Start the new computer and log in as normal, turn off the old computer and then hold down the “T” key on the key board while you restart it. The old computer appears as a hard drive on the new computer.
On the new computer, open the applications folder, and double click the migration assistant icon in the utilities folder.
Follow the instructions on screen to transfer files and other items from the old computer. Note, the migration assistant works only with computers running Macintosh OS10.3 Panther or later.
