How can I unlock my MacBook Air without losing data?

If you can boot your computer up in recovery mode and enter recovery mode without a password, you could potentially be able to open Disk Utility and plug in a flash drive. Bear in mind this method may produce errors that shouldn't affect your computer. You can erase the flash drive and click the restore button and select a volume in the Macintosh HD volumes shown in the dropdown selection, and confirm.

How to remove Activation Lock

How did you get to this point in the first place? I think we are missing some of the story here.

Are you the original purchaser of this Mac or did you buy it used?

Hi,

To unlock your MacBook Air without losing data, the most reliable method is to reset your password using your Apple ID. This can be done by entering an incorrect password three times at the login screen, which will trigger an option to reset your password using your Apple ID. You can also try using a recovery key if you previously enabled FileVault.

Had the same thought.

Glad you asked that question
