Need to transfer a mac's contents to one that is already set up
A year ago, my wife got a new macbook. I cloned her old mac onto the new one. For some reason she put off using the new one and now wants me to set it up again. Should I reset the new one to factory defaults first? If
so, how. Or, can I use the current Time Machine from her old mac to update the new one (which is set up & working, just missing a year's worth of her mods)?
