Hi, my Windows 7 PC got really old and it's now very slow. So I wanted to buy a new computer. I went to a technology store and I saw the MacBook Pro Retina. It was really beautiful. Then I watched an unboxing video on youtube. At the first boot up, there was a box sayin ''Transfer Information to this Mac'' and ''From a Mac, time machine or startup disk'' ''From a windows PC'' ''Don't transfer any information now''. I wonder what happens when you click ''From a Windows PC''? How can I transfer my files to Mac? Sorry for my bad english.
