MacBook Pro Account Lockout Timer Resets on Shutdown

Hi,

When you restart or shut down your MacBook, the macOS system clock often halts or resets. Because the account lockout timer is tied to a specific time, interrupting power causes the Mac to forget how much time has passed, or it defaults back to the initial, longer penalty period.

To break out of the infinite lockout and penalty loop, follow these steps:

Step 1: Wait out the timer or Bypass

1. Stop guessing passwords: Every failed attempt doubles the subsequent wait time (e.g., 1 minute → 15 minutes → 1 hour).
2. Leave the Mac on: Connect the MacBook to a charger and leave it running on the login screen until the stated countdown timer completely expires.

Step 2: Use Recovery Mode

If the timer does not decrease or keeps resetting on a restart, you can bypass the standard login screen entirely using Recovery Assistant.

1. Shut down completely: Press and hold the Power/Touch ID button for about 10 seconds until the screen goes completely black.
2. Enter Recovery: Press and hold the Power button again until you see "Loading startup options".
3. Select Options: Click Options, then click Continue.
4. Open Terminal: From the top menu bar, click Utilities, then select Terminal.
5. Reset Password: Type resetpassword (all one word, lowercase) and hit Return.
6. Follow Prompts: Use the on-screen options to reset your password using your Apple ID

Step 3: Resync the Keychain

Once you successfully log into your desktop using the new password, your local login keychain might still be desynced.

1. Open System Settings → Touch ID & Password.
2. Change your password again here to completely resync your local keychain cache and prevent future boot loop glitches.
