How to recover old Apple ID
I need my MacBook Air factory reset so my nephew can use it for his own. Please help! This is ridiculous! I have sold my MacBook Air to my nephew for college. I have forgotten my iCloud username AND password, now my nephew can’t even reset the MacBook. Please help me solve this! I want him to do the best he can in college.
