Change MacBook Pro OS X Apple ID ownership
You'd need to erase, then reinstall OS X. The drive (and all applications as well as the authentication data for that user's Apple ID are kept during the reinstall of OS X. Erasing the drive completely will remove all traces of any data on that drive. However, it will also delete all of your files. I'd recommend doing a manual backup and copy all the files from your desktop, documents, etc. to an external drive. Then enter recovery HD, erase the drive, and reinstall OS X.
