Connecting 2 Macs

Hi Guys,

Really hoping someone can help me on this! I have an iMac at the moment (Graphite DV SE version) and am waiting on my shiny new powerbook :love: arriving. When it does I want to connect one to the other to transfer my files. I’ve done this before in previous workplaces but I cant remember what cables I used. Im confused about whether it should be a crossover cable, an ethernet cable or a firewire cable?

Please help! Thanks!
