I've got a macbook (intel 2008 running Snow Leopard). It has been taking about 10 minutes to boot (stuck on blue screen) for about a month now. I took it to genius and they said it had a broken logic board. It does boot eventually, and works fine when it does. Instead of fixing the logic board, I bought an iMac (running Lion) to replace it. I'm trying to transfer files using target disk mode (firewire 400 on the macbook to 800 on the iMac). When booting using T, the macbook enters TD mode fine, the firewire logo comes up, but nothing happens on my mac. Nothing under devices in finder or on the desktop. Don't know if there is an issue with using FW400 to FW800? If so, is there a get around? Or is it just that my macbook is screwed?
