Start up old Mac while pressing and holding down the T key until
the FireWire
icon
appears
Connect your old Mac to the new one with FireWire cable.
An icon of your old Mac just as if it was an external hard drive
should appear on the desktop.
Copy data across same way as you do from an external hard
drive.
- Apple calls it 'FireWire target disk
mode':
You can even transfer data from dead (not booting up) Mac to PC
this way.
It works with almost all Macs made after year 2000.
