I downloaded Yosemite last night. I was going to run through it this morning but my son got to it before me. He said it asked questions, he answered and now I have a big grey box on my screen saying Setting up your Mac....
Is this supposed to happen? I have no idea what he has done, if anything. Can someone please advise? Thank you
