My MacBook Won't Turn on, Here is What To Do

By Jessica | Posted to Home > Mac Data Recovery Tips, Updated on September 17th, 2021

In general, Macs are reliable computers but not immune to problems.

Unexpectedly, your MacBook Pro won't turn on or iMac won't turn on and shows a black screen after you press the power button. Or macOS fails to start all the way up, like iMac won't boot past Apple logo or loading process is unbearably slow.

The reasons why your MacBook is not turning on vary a lot. Just follow the checks and techniques below, you have a great chance to make your Mac usable especially when your MacBook Pro won't turn on but is charging.

How to fix MacBook not turning on?

  1. Methods for MacBook not turning on:
  2. 1. Detach all external devices
  3. 2. Reset SMC
  4. 3. Charge MacBook for longer time
  5. 4. Perform a power cycle
  6. 5. Adjust display brightness or use an external monitor
  7. 6. Seek repair service

After you power on your MacBook, your MacBook will go through a series of complicated events. If all essential input and output hardware are functioning well, your MacBook will chime and the screen back-light will be activated.

If your MacBook Pro doesn't turn on, try the methods below to rule out possible causes.

Detach all external devices

During the power-on process, all internal and external devices will be checked, so a faulty accessory might cause your MacBook Pro or MacBook Air not turning on. For example, the accessory has short circuits or consumes unusual amount of power supply.

This works on all Apple Silicon and Intel-based Mac models - MacBook Pro, MacBook Air, Mac Pro, Mac mini, and iMac.

You need to unplug all unnecessary peripherals including a printer cable, external disk, HDMI cable, second screen, a Magsafe or type-C charger, and even a mouse. Then press down the power/Touch ID button on your MacBook again.

If external accessories don't result in MacBook Pro not turning on, reset SMC.

Reset SMC (Non-M1 Mac)

If your MacBook Pro won't turn on but is charging, you need to look into System Management Controller (SMC), which governs the entire MacBook power-on process. If your SMC has not received power or failed to assign power to hardware, your MacBook won't turn on.

To reset SMC on a MacBook:

On a MacBook with non-removable battery:

1. Completely shut down your Mac by pressing down the power/Touch ID button for 10 seconds.
2. Charge your Mac.
3. Press down Shift + Control + Option keys with your left hand and power/Touch ID button with your right hand simultaneously for 10 seconds.
4. Let go of all keys.
5. Press the power/Touch ID button to see if the MacBook Pro not turning on issue is resolved.

On a MacBook with removable battery:

1. Completely shut down your Mac by pressing down the power/Touch ID button for 10 seconds.
2. Take out the battery from your MacBook.
3. Wait for a few minutes until all electric energy discharges.
4. Put the battery back to your MacBook and turn on it again.

This method also works for Mac desktops, so you can try it when your iMac won't turn on. If SMC reset can't fix the MacBook not turning on problem, read on to try next method.

Charge the MacBook for 5 minutes or longer

If you haven't used your MacBook for a long time or the battery is dead or damaged, your MacBook won't turn on at all.

Usually your Mac laptop will power on as soon as you charge it with a working charger, but some models require a minimum battery power to trigger the SMC. Therefore, we recommend you wait for a few minutes until your battery power reaches that minimum level.

Charge MacBook

It is rare but too cold or hot condition will make your battery have a hard time charging. It could take up to hours before your Mac's battery finally charges and sends power supply to your Mac.

Then press the power/Touch ID button again to see if your MacBook turns on. If still MacBook Pro won't power on, perform a power cycle to force start the Mac.

Perform a power cycle for Intel Macs

If your MacBook is not responding to power button presses or lid-openings, you can perform a power cycle to force cut the power to it and force restart the Mac.

On a Mac laptop, you hold down the power/Touch ID key for 10 seconds. If you have a spinning hard drive disk, you will hear a squeak. If you have a solid-state drive, you won't hear anything.

On a Mac desktop, alternatively, you can directly unplug it for 10 seconds and plug it back to power.

This will force your Mac return to Off state and start refresh. If Mac won't restart, you need to troubleshot the Mac's display.

Adjust display brightness or use external monitor

If you keep seeing no images or videos on your screen, your MacBook Pro won't turn on sometimes because you have turned down the monitor's brightness to the lowest without your awareness.

Press the brightness up button a few times on your keyboard or on your Touch Bar on newer MacBook Pro models to increase the screen brightness.

You can also press the Caps Lock key to confirm your Mac is running if the light is on. If you can get some dim image or still no image on your screen, your Mac has a backlight problem.

Connect an external monitor to your MacBook if you need to use the Mac computer in a hurry.

Go to repair services

If your MacBook Pro won't turn on or charge after all above tactics, to fix your MacBook Pro not turning on problem, you need to consider asking local Apple Stores, Apple Authorized Service Providers or nearby third-party computer repair workshops for help.

Replace MacBook battery

The professional repairers will diagnose the issue and repair or replace the dead or malfunctioning components for you, from minor problems with ports, connectors, or cables to major breakdown in T2/M1/Intel chip, logic board or battery.

It can be costly, so remember to check your MacBook's warranty and get a free quote first.

How to fix Mac not booting up?

  1. Solution for Mac not booting up:
  2. 1. Start Mac in Safe Mode
  3. 2. Reset PRAM/NVRAM
  4. 3. Repair startup disk
  5. 4. Revive M1 Mac
  6. 5. Restore Mac
  7. 6. Reinstall macOS

If you can hear a startup chime, feel air movement from the vent holes, or see keyboard backlight, your Mac is turning on. After a short period of time, operating system will load up.

The booting for a modern operating system is a complex process and could be terminated or jammed by any hardware or software errors. It is common that Mac won't turn on after update, system crash or incompatible/malicious software installation.

Mac stuck on loading bar won't boot

We will run through another sets of checks and fixes to get rid of the errors that prevents the operating system from loading or initializing.

Restart your Mac in Safe Mode

When a Mac won't start, it may result from some certain startup items interrupting the booting process. To isolate these items from booting, your need to boot your Mac in Safe Mode.

It is a special startup option to limit some items from loading at startup. It also runs diagnostics to check the startup disk to fix your Mac.

To enter Safe Mode on Intel Macs:

1. Start the Mac up while holding down Shift Key.
2. Release the key until you see a startup screen.

To enter Safe Mode on M1 Macs:

1. Press and hold down Touch ID button until you see the startup options.
2. Select the startup disk while holding down Shift key.
3. Click "Continue in Safe Mode" and release the key.

You will see red "Safe Boot" in the top right of your menu bar. If you can successfully boot in Safe Mode, you can leave Safe Mode by restarting your Mac normally.

Mac Safe Boot

If the issue returns after you leave Safe Mode, startup items are probably to blame.

How to use Safe Mode to fix the Mac not starting up issue:

1. Go to System Preferences > Users & Groups in Safe Mode.
2. Click the account name under Current User and click Login Items.
3. Click yellow lock to enter admin name and password to enable changes.
4. Select all login items and remove them by using — button.
5. Restart the Mac normally.

If your Mac can't Safe Boot, or starting in Safe Mode can't resolve the problem, move on to another solution.

Reset the PRAM/NVRAM

NVRAM is a small amount of memory that your Mac uses to store certain settings and access them quickly. The settings include some information about startup process like startup disk selection, so resetting the PRAM/NVRAM might help with the Mac not booting up.

How to reset NVRAM on Intel Macs:

1. Start the Mac up while holding down Option + Command + P + R keys together for 20 seconds.
2. Release the keys after the second boot.

How to reset NVRAM on M1 Macs:

1. Press and hold down Touch ID button until you see startup options.
2. Click Options and click Continue to macOS Recovery Mode.
3. Open Terminal from the Utilities and run the command: NVRAM -c
Note: Even though you get an error feedback after running the command, it should still work.
4. Restart the Mac.

To be honest, resetting PRAM/NVRAM is seldom effective especially when iMac won't boot, but it won't hurt. You can scroll down to next fix to repair a corrupted startup drive.

Repair corrupted drive in macOS Recovery Mode

If the operating system isn't loading up, your system drive may be corrupted. The corruptions could reside in partition table, file system, or file system container (Macs running macOS 10.13 or above). Those corruptions will prevent boot loaders to read system data on your drive and result in a Mac not booting.

To fix the damaged drive containing operating system, you need to run First Aid tool in Disk Utility software in macOS Recovery Mode.

1. Boot your Mac into macOS Recovery Mode. Different Mac models require different ways to access Recovery Mode. Check the picture below.

2. Select Disk Utility from the macOS Utilities menu.

3. Select the Macintosh HD volume or the volume containing OS. Find out what to do if the Macintosh HD is not mounted.

4. Click on First Aid and click Run to repair the volume.

Disk Utility will find the errors and repair them automatically. You can run First Aid more than once to get a constant result. Frankly speaking, it also rarely useful.

If all attempts above can't help you start up your Mac, the next movements will contain Mac restore, OS reinstallation or M1 Mac reviving.

It is possible that your files stored on the Mac's hard drive will be deleted or permanently erased. Therefore, data recovery is essential before you proceed to next steps if you don't want to lose your important Mac files.

Recover data from a Mac that is not booting

If you have already backed up your important data, or you have a recent and full Time Machine backup of your Mac, you can skip this step and go ahead to the next operation.

You may wonder how you can rescue files from a Mac that isn't booting. Luckily, iBoysoft Data Recovery is a professional-grade data recovery software that can get your Mac files off an unbootable Mac. You don't need a second Mac or go to Apple Store to perform file recovery.

It only requires minimal knowledge and capability to boot your Mac to macOS Recovery Mode and run a command line.

How to recover data from Mac that won't boot up with iBoysoft Data Recovery

After securing the files, you can read the solutions below to make your Mac boot.

Revive M1 Mac

If you still can't boot up your M1 Mac after all solutions above, reviving the computer will update the firmware and recovery OS to the latest version and eventually reboot your device.

A revive won't make any changes to the startup volume, user's data volume, or any other volumes, which is different from a restore.

To revive your M1 Mac, you will need:

  1. • A USB-C cable
  2. • A second working Mac
  3. • An adapter if needed
  4. • Internet access/Wi-Fi
  5. • Latest version of Apple Configuration 2 installed on the working Mac running macOS 10.15.6 or above

How the revive processes work:

1. Charge the M1 Mac that won't turn on and the other Mac too.

2. Connect two Macs with a USB-C to USB-C cable (along with any adapters needed).

3. Open Apple Configurator 2 software on the working Mac.

4. Prepare the Mac you want to revive in DFU Mode:

On a Mac desktop: disconnect the computer from power > hold down the power button and connect the computer to power > keep holding down the power button for 10 seconds until a DFU icon shows up on the M1 Mac.

On a MacBook: shut down the Mac completely > ask for somebody else to help you with holding down the power button and you hold down the right Shift + left Option + left Control keys together for 10 seconds > keep holding the Touch ID button and release the keys until a DFU icon shows up on the M1 Mac.

5. Right-click the selected DFU icon and then choose Advanced > Revive Device.

6. Click Revive to confirm and wait for the process to complete.

Your M1 Mac might experience multiple shutting down and restarting until the revive completes. If the revive is successful, your Mac will reboot. If not, you can choose to restore your Mac to a previous state or reinstall macOS.

Restore Mac

If your Mac isn't finishing the booting process, it is a good idea to roll your Mac back to a previous state that has been working properly. This method works extremely well especially to fix macOS update stuck.

You have two options to restore your Mac:

Option 1: Restore with APFS snapshot (macOS 10.13 or later). APFS file system will takeautomatic snapshots to create backup pointswhile you are doing a regular macOS update. It will involve Time Machine utility in Recovery Mode, but it doesn't require Time Machine backup.

Option 2: Restore with Time Machine backup.

How to roll back to an APFS snapshot point in time:

1.Get files off the Mac first because you will not be able to restore files and software that are saved after the snapshots are taken.

2. Start up your Mac in macOS Recovery Mode.

3. Select "Restore From Time Machine Backup" and click "Continue".

4. Select the startup disk where APFS snapshots are stored and click "Continue".

5. Select the latest snapshot in the list sorted by date and macOS versions and click "Continue".

Restore Mac with local APFS snapshots

6. Confirm the restoration by clicking "Continue" on a pop-up.

After the restore completes, your Mac will reboot automatically. Using APFS snapshot to make your Mac boot doesn't require a reinstallation of the old macOS, so it is faster than reinstalling macOS.

If you are running an OS earlier than macOS 10.13 or APFS snapshots are too old, you can reinstall Mac OS.

Get a new macOS

We understand the OS reinstallation is your least wanted method. If you have tried everything but still can't remove the problem that stops your Mac from starting, reinstalling a fresh copy of a working operating system should fix any software-related errors.

This approach applies to most recent versions of macOS and OS X.

It is easy to reinstall macOS because Mac has such a utility to instruct you all the way in Recovery Mode. However, it can be time consuming if your internet connection is slow or the installation file is large. Just be patient and don't let your computer shut down or sleep midway.

Contact Apple Support

If you have made to this far but your Mac still refuses to start all the way up, just use Apple's customer support to make things simple.

Apple offers comprehensive and free technical supports through telephone, online, and Apple Retail Store Genius Bar. Do not hesitate to reach out to an Apple expert to help you out with your Mac product stuck on booting problem.

Mac Won't Turn on VS. Mac Won't Boot

A not turning on Mac means a Mac that is not responding at all after you press down the Power/Touch ID button. You don't hear a startup chime, a spinning fan, drive noise, and there are no visuals on your monitor. Your Mac looks completely dead.

A Mac not starting up is a Mac that turns on but the operating system isn't loading up. Your Mac boots to a strange screen, an unfamiliar symbol or never finishes the progress bar. Your Mac is still alive but is not functioning properly.

A unresponsive Mac machine requires completely different techniques to one that is not booting.
