Changing the name attached to my MacBook Pro 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"?
You need to change your personal contact card in Address Book, soon to be Contacts in Mountain Lion.

In order to do this, launch Address Book and create a card with your information in it.

Then, while your card is selected, go to the Card menu and select "Make This My Card".

Note:  I'm not sure if Xcode has a stores this info elsewhere or not, but anything new that you install will definitely get this updated info.
