Q: My computer Locked me out what should I do?

Greetings Leticia new Rochelle,

Welcome to the Apple Support Communities!

It sounds like you may not know the administrator password for your Mac. If this is the case, please use the attached article for information on resetting that password. If this is not the case, please let me know more about your situation and how your computer locked you out.
