#Tip 1: Create a New User Account in Single User Mode

If you have previously created a spare Admin account for accidents, then it's time to try it. If you haven't, you have to follow the below steps to create a new one since you are locked out.
Step 1: Turn off your Mac if it's not. Press and hold [Command]+[S] to enter Single User Mode after tapping the power button.
Step 2: After lines of codes scroll up, a command prompt will appear with a line: :/ root#
Step 3: This step helps you to access your files in your Mac: Type or copy the below line into the prompt and hit [Enter]: /sbin/mount -uw /
Step 4: This step will remove a file so that your Mac will think it's your first time to log in: Type or copy the below line into the prompt and hit [Enter]: rm /var/db/.applesetupdone
Step 5: Type in: Reboot and tap [Enter]. Then you can create a new account just like the first time you start your MacBook.

#Tip 2: Reset your Mac's SMC and PRAM

#Tip 3: Press Shift Button When Log in

This method can bypass any login item in your user profile.

  1. Start your MacBook normally.
  2. On the Login page, enter your password, but DON'T click on Log in immediately.
  3. Press and hold the SHIFT key, and then, click on the Login button.

 

#Tip 4: Boot In Safe Mode

Safe mode is designed to protect MacBook's starting from third-party files and apps. It will automatically check your starting disk and even repair directory issues if needed. Meanwhile, it can block the automatic running of startup items which may affect login process and only load required kernel extensions. Therefore it might help you isolate the cause which makes your MacBook stuck on login page. The method of prompting safe mode is shown below:

  1. Make sure your MacBook Air is off.
  2. Press the power button and immediately press & hold [Shift] button until the Apple logo appears on the screen.
  3. Release the key when you see the login window. You may be asked to log in twice if startup disk is encrypted with FileVault.
