Wipe clean 2010 MBP
Have a MBP Mid 2010. Do not have original disks. I would like to wipe the device before I give it to a granddaughter. Please let me know what I should do. I presume I could erase the HD with Disk Utility...and I don't know if that affects the OS.
Thanks for considering my request.
