I am selling my Macbook Pro Retina tomorrow and I am doing a clean reinstall for the buyer. However, in order to re install the OS via the Recovery option with the Command + R at reboot, it needs an Apple ID to verify the OS X Yosemite download through the App Store. I am more than happy to use mine IF my Apple ID does not tie anywhere into the buyer's computing experience on this computer. Does anyone know if the OS install via my Apple ID will tie into the rest of the buyer's experience?
