How to Fix MacBook Won’t Boot or Start?

Your MacBook won’t boot or start up? Here are some solutions that may help get it going again.

Check your power supply

If your MacBook won’t start up, the first thing you should check is the power supply. Make sure that the power cord is plugged in securely and that the outlet you’re using is working. If you’re using a battery pack, make sure it has enough charge.

If everything looks good with the power supply, the next step is to reset the SMC (System Management Controller). This can fix a whole host of issues, so it’s worth a shot even if you’re not sure what’s wrong.

To reset the SMC, follow these steps:

1. Shut down your MacBook.
2. Press and hold the left Shift key, the left Option key, and the left Control key on your keyboard.
3. While still holding those keys, press and hold the power button for 10 seconds.
4. Release all the keys and press the power button to turn on your MacBook.

Once your MacBook is back on, try booting it up again and see if the problem is fixed.

Check for updates

If your MacBook won’t boot or start, the first thing you should do is check for any software updates that may be available. To do this, open the App Store app on your Mac and click the Updates tab. If there are any updates available, install them and then try restarting your MacBook again.

If that doesn’t work, move on to the next section.

Run Disk Utility

If your MacBook won’t boot or start-up, one thing you can try is running Disk Utility. This utility can help fix minor errors on your hard drive that might be causing the issue. To run Disk Utility, follow these steps:

1. Insert your Mac’s installation DVD or use the Recovery HD partition.

2. From the utility menu, choose Disk Utility.

3. Select your startup drive from the left side of the window and then click the First Aid tab.

4. Click Verify Disk to check for errors and then Repair Disk if any errors are found.

5. Quit Disk Utility and restart your MacBook to see if it will boot up properly now.

Reset the NVRAM

If your MacBook won’t boot or start-up, one thing you can try is resetting the NVRAM. This stands for non-volatile random-access memory, and it’s where your Mac stores certain settings and accesses them quickly. By resetting the NVRAM, you might be able to fix issues with things like your display, sound, time zone, and more.

To reset the NVRAM on your MacBook, first shut down your computer. Then press and hold these four keys together: Option, Command, P, and R. You’ll need to hold them down until your MacBook restarts and you hear the startup sound for a second time. After you’ve done that, let go of the keys and your MacBook should boot up normally.

If resetting the NVRAM doesn’t fix your issue, there are a few other things you can try. One is to check for any updates to macOS that might be available. Another is to use Apple’s Hardware Test to see if there are any issues with your Mac’s hardware. And finally, if all else fails, you can always try restoring your MacBook from a backup.

Reinstall macOS

If your MacBook won’t boot or start, one potential solution is to reinstall macOS. This will erase your Mac’s hard drive and install a fresh version of the operating system. Before you proceed, be sure to back up your important files and data.

To reinstall macOS, follow these steps:

1. Shut down your MacBook.
2. Press and hold the Command (⌘) and R keys simultaneously as you turn on your MacBook. Keep holding the keys until the Apple logo appears on the screen.
3. Wait for the OS X utility window to appear, then choose Reinstall OS X from the menu.
4. Follow the prompts to reinstall macOS.

Get more help from Apple

If your MacBook still won’t start up, you can get more help from Apple. You can make a Genius Bar reservation at an Apple Store, visit an Apple MacBook repair London shop, or contact Apple Support.

When you contact Apple Support, have your serial number ready so they can help you identify your MacBook and troubleshoot the issue.


If you’ve been having trouble with your MacBook won’t boot or start-up, don’t worry — there are a few things you can try to fix the issue. First, check to see if your MacBook is plugged in and receiving power. If it is, then try restarting your computer. If that doesn’t work, try resetting the SMC (System Management Controller). If none of these solutions work, then you may need to take your MacBook to an Apple Store or authorized service provider for further diagnosis and repairs.
