Bored cocktail-party companions will know that I went through a two week period of enforced disconnection from my Mac (yet another logic board failure). Happily, the machine is back, and they even cleaned it up and gave me a new keyboard.
My Mac Won't Start! A Tiny Guide is a little eight page, single sheet of paper booklet folded in pocketmod style that gives you all of the basic troubleshooting tools you need to boot into safe mode, fsck the disk, or boot to Firewire mode so that you can mount the drive remotely.
This troubleshooting guide was co-created by two designer-friendly computer support firms: CreativeTechs in Seattle and Forget Computers in Chicago. Both companies have spent years helping creative teams stay productive with today's changing technology.
If tech origami is not your style, they also have a non-pocketmod format page.
