To reset a MacBook password, there are several methods depending on whether the Mac is linked to an Apple ID, if you have a FileVault recovery key, or you need to use macOS Recovery Mode.

Reset Using Apple ID

• After entering a wrong password three times at login, select the option to reset using your Apple ID.
• Enter your Apple ID credentials and verification code (if two-factor authentication is on).
• Choose the user account, create a new password, and restart to log in.

Reset Using FileVault Recovery Key

• On the login screen after failed attempts, select reset using recovery key.
• Enter the 28-character FileVault recovery key.
• Create a new password and reset.

Reset in macOS Recovery Mode

• For Intel Macs: Turn off the Mac, then hold Command + R and power button until Apple logo or spinning globe appears.
• For M1/M2 Macs: Turn off the Mac, then hold the power button until startup options appear; select "Options" then "Continue."
• In Recovery Mode, go to Utilities > Terminal, type "resetpassword" and press Return.
• Use the Reset Password Assistant to select your user account and create a new password.
• Restart the Mac and log in with the new password.

These methods provide a way to regain access safely depending on the setup of the MacBook.
