mini: My old Mac Mini is VERY slow, and out of memory. I purchased a new iMac desktop computer about a year ago. When I went to the Apple store to ask about transferring data, the worker gave me a firewire cable, capable of being plugged into both kinds of ports. There is just one problem, the Mac Mini hard drive doesn't show up on the desktop like he said. Any Help?How does one transfer data from a Mac Mini to a new iMac?You have to start the mac mini in target disk mode for that to work. Start up the target computer and immediately press and hold down the T key until the FireWire icon appears. The hard disk of the target computer should become available to the host computer and will likely appear on desktop. http://support.apple.com/kb/HT1661How does one transfer data from a Mac Mini to a new iMac?There are two ways to do it with a FireWire cable: 1) Boot up both Macs and connect them using the FireWire cable. The open Migration Assistant on the iMac (open Finder and go to Applications->Utilities->Migration Assistant). It will prompt you to open Migration Assistant and enter a specific string of numbers: do that, then follow the directions. That will let you transfer all your personal files and apps from the Mini to the iMac. It might take a while so be patient. 2) Boot the Mini into Target Disk Mode by holding the "T" key right when you hear the start up chimes when you reboot. Keep holding T until you see a FiewWire symbol on the screen. Then plug the FireWire cable into the iMac. You will see the Mini mount like an external drive on the iMac's desktop. You can open the Mini in finder on the iMac and transfer manually just the files you want, or you can open Migration Assistant (like above) and transfer all your personal files from the Mini. If you want to move everything over (docs, movies, music, apps, photos, etc) all at once, use Migration Assistant. If you only want to move a few files or folders (like just your pictures) mount the Mini as Target Disk and simply drag the photos folder to your iMac. Easy! Enjoy!
