How can I unlock my MacBook Air if I forgot the password?

Hi 1304-Kelly,

welcome to the Apple (user-to-user) Community.

Re: How can I unlock my MacBook Air if I forgot the password?

Wondering if you tried the steps in the "Related Article" above your question, and what happened if you did.

If you forgot your password, and / or Apple ID:

What to do: If you can't reset your Mac login password

If needed:

Find out what to do if you see the Activation Lock screen on your device:

Activation Lock for Mac – Apple Support

and

How to remove Activation Lock - Apple Support

If you need more help, it would help us to know:

which MacBook Air model (year) you want to unlock:

Identify your MacBook Air model – Apple Support

and

which MacOS version is installed.

All the best :-)
