I bought a MacBook Pro Retina, and it's my first OS X computer. During setup, I had a brain lapse and entered my mom's email address instead of my own. I don't remember what it was I was setting up, but I believe it had something to do with Apple ID. My mom has a MacBook herself.
I'm not talking about the computer name. The computer is named correctly. Also, iTunes and the App Store are linked to my own Apple ID.
Later, when I opened up Xcode, I found that new Objective-C files have my mom's name in the comments section at the top.
I just installed Parallels and also found that during registration my mom's name and email address appear pre-filled for me.
I have no idea what to do to change this. Any idea how I can retake "ownership"?
