My wife bought a Macbook Air 2 days ago and she assumed I could get her on line and up to speed quickly. That being said I was able to set it up - connected to our wireless network and installed our HP printer - hoo rah. Unfortunately, that's where I came to grindoing halt. I can't even figure out how to create new folders to store Word & Excel files I want to transfer from her PC. Is there a Mac Functionality reference that provides some sort of translation from PC to Mac functionality?
