Change Apple ID on MacBook Air
I recently purchased a MacBook Air. I wanted to use it mainly for school, so I made a new Apple ID. However, in retrospect I wish I had used my original Apple ID. I would like to purchase Apple Care and I keep getting an error message regarding the Apple ID.
Is there a way to change the Apple ID to my original one without losing data on computer? Also, I do not want all of my pics to transfer over as I would like to use mainly for work purposes.
Thank you,
Michele
