You prepare to use Mac Safe Mode to fix OS-related issues, such as MacBook won't turn on, Mac running slowly, or can't install macOS Sonoma. But unfortunately, you fail to boot into Safe Mode. Your Mac simply starts up normally, or it's stuck during booting up to Safe Mode.

Mac won't start in Safe Mode but boot up regularly

You press the Shift shortcut key during the startup to make your Mac start in Safe Mode as usual. But unexpectedly, you see the familiar desktop as a regular startup.

To check and fix the MacBook Safe Mode not working issue, you can follow these solutions.

Check if you were actually in Mac Safe Mode

Since the desktops in Safe Boot and Normal startups seem similar, you may enter into Safe Mode indeed while you ignore them.

In normal mode, the Dock color is similar to that of your desktop. But in Safe Mode, the Dock color will become light grey.

If you still can't tell the differences between them, you can try the way below to check if your Mac is in Safe Mode.

If it shows Safe, you are in Safe Mode. And if it indicates Normal, your Mac boots up regularly rather than into Safe Mode. Then, you can try to reboot your Mac into Safe Mode once a time.

Check if your way to boot your MacBook into Safe Mode is right

Sometimes, your wrong operations to boot a Mac in Safe Mode lead to your failure. So, you'd better ensure every step of your way to Safe Mode is right.

When your Mac fails to boot in Safe Mode, do the following checks:

• Check if you use an Intel-powered Mac or an M1 Mac.
• Make sure your Mac machine is completely powered off before restarting it to Safe Mode.
• Don't just hit the Shift shortcut key and release it immediately but press it down for seconds.

If you have no idea about that whether you do the right job in every step to boot your Mac into Safe Mode, you can take the above steps to start a Mac in Safe Mode as references.

Check if your keyboard works well

Finally, you can check if your keyboard is dead by pressing it down and simultaneously typing any letter to see if you can type a capital letter. If not, the Shift key is out of work. Change a keyboard. If it happens again, fix the USB port.

If you are using a wireless keyboard, open System Preferences > Keyboard. Check if you fail to connect a Bluetooth keyboard and reset it.

After confirming you have a workable keyboard, restart your MacBook Pro in Safe Mode now.

Mac takes forever to boot to Safe Mode

In this scenario, the causes vary. Your Mac that is stuck in the booting process to Safe Mode may be because:

• Temporary bug in macOS.
• Security settings limitations on your Mac.
• OS-related issues.

Therefore, you can try the following solutions to troubleshoot your Mac which takes forever to enter Safe Mode.

Reboot your Mac into Mac Safe Mode

The temporary bugs in Mac OS will lead to abnormal performance of your Mac, such as the Mac won't start in Safe Mode in macOS Big Sur.

So, when your Mac takes forever on the process to Safe Mode, you can try to force shut down your Mac and wait a few seconds. Then, boot it into Safe Mode again.

Check your security settings

If your Mac Safe Mode still not working, think about if you've configured security settings to protect your Mac, like FileVault and Mac firmware password. These security settings may trigger Safe Mode to be stuck or hang forever.

To turn off FileVault (Only if your Mac can boot up), you can follow these steps:

If you've also enabled the Firmware password, you should close it as the steps below:

The process to disable the security settings will take some time. Please wait until it finishes and then, reboot your Mac computer in Safe Mode.

Reset SMC

SMC (System Management Controller) controls the thermal and power management, sleep settings, etc., mattering your Mac performance.

Resetting SMC can fix hardware not functioning issues, such as the keyboard not working which causes Mac Safe Mode to not work.

Reset SMC on a MacBook:

Reset SMC on a Mac desktop:

Now, you can try to restart your MacBook in Safe Mode.

Reset PRAM/NVRAM

PRAM stands for Parameter Random Access Memory (NVRAM is similar). It is a memory used to store system-related settings, including the startup volume choice.

If your Mac behaves abnormally, such as can't start up in Safe Mode, you can try to reset the PRAM/NVRAM to fix the trouble.

Now, go to restart your Mac machine in Safe Mode.

By the way, you don't need to reset PRAM on an M1 Mac because it will automatically reset if needed during startup.

Boot in macOS Recovery mode

Unfortunately, all the ways mentioned above are useless for fixing the Mac Safe Mode not working issue. The culprits may be the file system errors on the startup disk. These errors can not only set off the Mac won't boot, but also prevent you from using Safe Mode.

In this situation, you need to use Mac Recovery Mode. When entering macOS Recovery mode, you can use Disk Utility First Aid to check and fix the errors on your startup disk.

If your Mac still fails to boot, you have to recover data from your unbootable Mac first. Next, format Mac startup disk with Disk Utility, and then reinstall macOS in recovery mode.

How to start a Mac in Safe Mode properly?

If you prepare to boot your MacBook, iMac, Mac mini, or other Mac models to Safe Mode, you should check if it has an Intel chip or an Apple M1 chip first. That's because the way to start an Intel-based Mac and M1 Mac in Safe Mode is slightly different.

Go to the Apple logo > About This Mac > Overview. Then, check the Chip or Processor of your Mac.

Then, you can follow the proper way below to boot a Mac in Safe Mode.

To boot an M1 Mac in Safe Mode, you should:

By the way, you can exit Safe Mode by selecting the Apple menu > Restart.
