Proven methods to fix MacBook Air stuck on loading screen

Some Mac users report that the MacBook Pro stuck on loading screen with the Apple logo, MacBook Pro stuck on loading screen with loading bar, MacBook won't load after a macOS update, or even the Mac progress bar stuck at 100%.

If any of the above scenarios befalls you, try the following 10 solutions to fix. They are also applicable when your Mac stuck on login screen or your iMac won't boot past Apple logo.

Solution 1: Disconnect the peripherals & Restart your Mac

Restarting Mac is a quick fix when your MacBook Air/Pro/iMac encounters a boot problem. This way is easy and sometimes works. And as we said before, malfunctioned peripherals will also give rise to Mac stuck on loading screen problem. So, you'd better disconnect all peripherals.

  1. Press and hold the power button for a few seconds to turn off Mac.
  2. Disconnect all peripheral devices from your Mac.
  3. After a few minutes, press the power button to restart the Mac.

Solution 2: Boot your Mac into Safe Mode

MacBook stuck on Apple logo with loading bar could be caused by software conflict or incompatibility. So, to confirm it, boot Mac into Safe Mode. It will prevent your Mac from launching unnecessary programs and login items at startup. It also does a basic check of your boot disk and solves some of the Mac slow startup issues.

To boot your Intel-based Mac into Safe Mode:

  1. Force your Mac to shut down.
  2. Press and hold the Shift key while tapping the power button to start your computer.
  3. Release the Shift key until you see the Apple logo and loading screen. Then it gets into Safe Mode.

Boot your Mac into Safe Mode

To boot your Apple M1 Mac like M1 iMac into Safe Mode:

  1. Shut down your Mac and wait for seconds.
  2. Press and hold the power button until the startup disks and Options appear on the screen. 
  3. Press and hold the Shift key, then click Continue in Safe Mode.

If your Mac boots past the loading bar and enter Safe Mode successfully, you'll see "Safe Boot" on the right top of the screen. That also shows the culprit is the software conflict.

Find out the conflicting program or software, usually the recently installed third-party software, and then uninstall apps. Next, you can simply reboot your Mac. If your MacBook Safe Mode is not working, try the next solution.

Solution 3: Reset NVRAM/PRAM

PRAM or NVRAM is a non-volatile random access memory. It is used to store system settings on Mac, including startup disk selection and recent kernel panic information. So, when the MacBook stuck on Apple logo with loading bar, resetting NVRAM/PRAM might get your stuck MacBook Pro fixed.

To reset NVRAM/PRAM, you can simply restart your Mac and simultaneously press Command + Option+ P + R keys. If you have an M1 Mac, you don't need to reset NVRAM. Because it will automatically run test and reset on startup if something went wrong.

Solution 4: Reset the SMC

SMC (System Management Controller) is used to control a number of Mac core functions, including sudden motion sensor and thermal management. Typically, when MacBook Pro stuck on loading screen, SMC reset helps to resolve such unresponsive issues related to power and hardware.

To reset the SMC on a Mac computer stops loading halfway, follow the steps below. Note that there is no SMC on M1 Mac.

Reset SMC on MacBook Air and MacBook Pro

  1. Force shut down the Mac that is frozen on loading screen.
  2. Press Shift + Control + Option on your keyboard and press the power button at the same time.

  2. Wait 15 seconds. Then, plug the power cord in.
  3. Wait several seconds and turn on your computer by pressing the power button.

Solution 5: Reselect the startup disk

Sometimes, the Mac stuck on the loading bar results from your last booting from an external hard drive or the other internal hard drive (if you have two). In this scenario, you need to reselect the startup disk.
