I've searched the forums and haven't quite found the scenario I'm in. I have a Mac Mini...bought in 2009 with Snow Leopard...I have since upgraded each time and am currently running Mavricks. I'm FINALLY getting a Macbook Pro in a few days and what I would like to do is transfer all of my info to the Macbook...and then erase the Mini and give it to my Wife. All that I have read instructs to erase, reformat, & reinstall Snow Leopard...but I really wanted to keep Mavericks on it for my Wife and didn't want to have to buy the upgrade AGAIN...so is there a way to wipe the data without reformatting and reinstalling the OS?
