3. Conclusion

This guide to fix Mac stuck on the loading bar issue applies to macOS Catalina, Mojave, High Sierra and some older Mac OS X.

First, let's start with the causes.

Why is my Mac stuck on the loading bar screen?

Normally, Mac would show an Apple logo at startup when it finds your local startup disk. Then, based on if you have encrypted the startup disk, a loading bar appears after or before you log in to the Mac.

The loading bar indicates that the system is checking and loading macOS from the startup disk. It involves macOS structure, corn components, file system, security chip, etc.

However, if something is not going well, the progress bar will get frozen at startup. For instance, the updated software is not compatible with your Mac models. Or the file system of the startup disk is corrupted after an unforeseen shutdown.

No matter what the reason is, this issue will prevent you from booting up your Mac.

The good news is, even though your Mac stuck on login screen, you can fix this issue with 7 available solutions. Now, let's try them one by one and fix the Mac stuck on loading bar screen issue.

Solution 1: Restart your Mac when Mac progress bar stuck

Whenever you encounter the boot problem, you can try rebooting the computer. Though not always work, it won't hurt.

When your Mac is stuck on loading screen, you cannot shut it down from the Apple menu. But you can press and hold the power button for a few seconds to turn off the Mac. Then, you can disconnect all peripheral devices from your Mac. This will isolate the problem and leave the Mac alone

After a few minutes, you can restart the Mac again. Does your Mac boot past the loading bar screen?

Solution 2: Boot your Mac in Safe Mode

Mac stuck on startup screen with status bar could be caused by software conflict or incompatibility. So, to confirm it, you can boot the Mac into Safe Mode. A Safe boot will prevent your Mac launching unnecessary programs and login items at startup. It also does a basic check of your startup disk.

To boot your Mac into Safe Mode, you need to:

  1. Step 1: Force your Mac to shut down.
  2. Step 2: Press and hold the Shift key while tapping the power button to start your computer.
  3. Step 3: Release the Shift key untill you see the Apple logo and loading bar.

If your Mac loads successfully in Safe Mode, it's surely a software or firmware conflict. To find out the exact conflicting program, you need to restart your Mac in Verbose mode with these steps.

  1. Step 1: Restart your Mac and immediately hold Command + V at startup.
  2. Step 2: Let the keys go after you see the Apple logo.

Instead of a plain loading bar, you will see the booting progress report in Verbose mode. With the live report, it's easier to find out which software stops your Mac from starting up. Then, you can simply reboot your Mac into Safe Mode and get rid of it.


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 Mac won't boot after macOS update or get stuck at 100% progress bar,resetting NVRAM/PRAM might help. You can simply restart your Mac and simultaneously press Command + Option+ P + R keys. Then, you can restart it again.

Solution 4: Reset the SMC

SMC, short for System Management Controller, is incorporated into the Mac's motherboard. It is used to control a number of Mac core functions, including sudden motion sensor and thermal management. Typically, when Mac freezes on startup, SMC reset helps to resolve such unresponsive issues related to power and hardware.

To reset the SMC on a Mac computer that is stuck on loading screen, you need to at first determine whether the battery is removable or not. The process of resetting SMC of a non-removable battery is quite different.

1. Reset SMC when MacBook Air and MacBook Pro stuck on loading screen

If the battery is removable:

  • Step 1: Turn off your MacBook.
  • Step 2: Remove the battery.
  • Step 3: Press the power button and hold it for a few seconds.
  • Step 4: Reinstall the battery.
  • Step 5: Press the power button to turn on your Mac.

  • Step 1: Force shut down the Mac that is frozen on the loading screen.
  • Step 2: Press Shift+Control+Option on your keyboard and press the power button at the same time.
  • Step 3: Hold these keys for 10 seconds.
  • Step 4: Release the keys.
  • Step 5: Press the power button again to turn on your Mac.

It helps if there is a disk error on Mac internal hard drive. So you can give it a try to fix the Mac stuck on apple logo with loading bar issue.

If First Aid successfully found errors and repaired them, you can restart your Mac. Disk Utility helps Mac boot up, and your Mac desktop or MacBook should boot past the loading bar screen and turn on then.

Solution 6: Reformat the startup disk and reinstall macOS

But sometimes, even First Aid won't work if the startup disk is severely corrupted. In this case, you might want to erase the startup disk in macOS Recovery mode. Disk erasure will reformat the hard drive with a new file system.

This usually will fix this issue. However, at the same time, it will wipe all your files off the drive. So, if you have important files on this Mac, you should first rescue data from the corrupted hard drive. It's necessary especially if you don't have any backup.

If you don't worry about data loss, you can proceed with reformatting the Mac hard drive.

1. How to reformat the corrupted startup drive?

  • Step 1: Restart your Mac into macOS Recovery mode.
  • Step 2: Select Disk Utility from the macOS Utilities menu and click Continue.
  • Step 3: Select the Mac hard drive (often named Macintosh HD or Apple SSD) from the left sidebar.
  • Step 4: After clicking Erase on the top, you need to name it as Macintosh HD, and then give it a scheme and format.
  • Step 5: Click Erase to confirm this operation, and then wait it to complete.

Now, you have an empty but workable Mac hard drive. To boot your Mac again, you need to continue with the next part.

Solution 7: Restore macOS with local APFS snapshot

It's inevitable that a macOS update is not compatible with your Machine. So if your Mac gets stuck on the loading bar screen because of a recent macOS update, you may want to revert to the previous state.

If your Mac won't boot past Apple logo or have other problems after macOS Catalina update, you may want to downgrade it.

Fortunately, in macOS High Sierra or later, an APFS snapshot is saved before installing any macOS update. And you could restore your previous OS with the APFS snapshot. But this may erase your hard drive, so you also need to back up data on the unbootable Mac first.
