I need to transfer information through firewire cable and could not remember how it works, please, help

Question

Please help, I need urgently to transfer information through firewire cable and I could not remember how it was that I do it. I've connected the computers and restarted one of them by pushing T on startup but it did not work.

Answer 1

Shut down both Macs.  Connect them via FW cable.
On the Mac you want to copy FROM.  Start up but make sure you are holding down the T key as soon as you press the power button.  And keep holding down the T key until the FireWire emblem appears on the screen - that's the indicator that the Mac is in Target Disk Mode (TDM).  Note: if you release the T key too soon the Mac won't go into Target Disk Mode.
Start up the second Mac.  The first Mac will appear in the Finder as a disk.  You can use the Finder to copy whatever you want from the Mac that's in TDM.
When you're done, shut down both Macs.  The Mac that's in Target Disk Mode can be shut down by holding down the power button until it turns off.
