Mac not turning on with white screen

If you've suddenly found yourself in a situation where your Mac or MacBook is not turning on, it can be incredibly frustrating. Suddenly, you find yourself panicking. Tons of worries are going through your mind, such as:

"If my Macbook or Mac won't turn on now, will it ever turn on again?"

"Will I lose a ton of files, such as my work and pictures?"

"What does this black screen even mean? What will happen to my computer?"

This can be an incredibly stressful situation to find yourself in. However, you shouldn't worry.

Usually, once you've tried out a few troubleshooting techniques, you should be able to start your Mac or Macbook again.

Finally, you can relax, knowing that there's a way to fix the problem so that you can turn on your Mac or Macbook again. Read on to learn more.

Mac or Macbook is not turning on? Here's how to prepare for troubleshooting

When your Macbook or Mac won't boot up, you first need to prepare for troubleshooting. To do this, you need to understand how to turn on your Mac. Depending on the model you have, there are different ways to do this. Let's start with newer MacBook models.

With these models, there isn't actually a power button. Instead of looking for it, look for a black square that doesn't have any markings at all that appears at the top right of your keyboard.

In addition to working as a power button, this square is your MacBook's Touch ID sensor.

To turn your new MacBook model on, you need to press this sensor. This should power up your MacBook if it's working properly.

If you have an older MacBook, then you can find the power button easily because it's clearly marked. You can find it at the top right of your keyboard, near the function keys.

For iMac owners, the power button is at the back of the computer, on the left corner on the bottom (this is when you're facing your screen). If you have a Mac Mini, you can find its power button in the back, in the right corner.

1. Check the display

Check if the display is ok. If you are using an external display, make sure the video cable is seated properly at both the display and the Mac ends of the cable. Check the power cable as well. If it is loose, you need to reconnect the cable firmly at both ends.

2. Check the power source

The first thing you need to do is check your Mac's power source. Even though it may seem like an obvious step to take, many people forget to check the power source. To do this, plug your MacBook in. If it turns on, then this means one of two things:

  • The battery was fully depleted, which is why it wouldn't turn on
  • The batter is malfunctioning

If you're okay with doing your work on your laptop while it's plugged in, then you won't have to do anything else and your problem will be solved. However, if you want to use your laptop at a cafe, you'll have to wait for it to charge (or get the battery replaced if it's malfunctioning).


However, sometimes plugging your MacBook in still won't solve the problem of your MacBook not turning on.

If your MacBook won't charge, the next step you have to take is to check if the charger isn't damaged and that you've connected it to your computer properly. If you have another power cable around, try out that one.

You should also look at the port. Is it dirty? If so, clean it out. If dust has built up in the port, this can disrupt MagSafe chargers and USB-C ports.

Additionally, see what's going on with your external hardware. If you have any peripherals such as graphics tablets or printers, disconnect them. They might be the reason why your computer isn't charging.

Mac Mini

With Mac Mini, double-check that the monitor is powered and connected properly.

3. Run a power cycle

If you've checked the power source and your Mac or Macbook won't boot, the next step is to run a power cycle. When you do this, all the power is totally cut out of your Mac or MacBook. This means that you can restart it fully, completely powering it back up again.

Running a power cycle works differently on different Mac and MacBook models.

Recent MacBook model

If you have the most recent MacBook model, you first need to disconnect the computer from the power cable. Then, hold down the power button, doing this for 10 seconds.

Older MacBook model

With an older MacBook, you should disconnect the computer from the power cable. Next, remove the battery. Have the battery out of the computer for at least 10 seconds.

Desktop Mac

If you have a desktop Mac, then all you have to do is disconnect it from the power cord. Do this for at least 10 seconds.

Whatever model you have, the next step is the same for all of them. Reconnect your computer to the power cord, and then attempt restarting your Mac. This might be enough to bring the power back.

The reason this is so effective is that it functions like pressing a reset button.

4. Boot your Mac up in safe mode

Sometimes, a Mac suddenly shuts off when you're doing something complicated on it. Maybe, the last time your Mac or MacBook was on, you were tweaking its system or installing apps. Whatever the process, it may have been too much to handle for your Mac.

Now, when you try to start your Mac, it starts for a second before shutting off again. For example, you might be able to see the login screen or the Apple logo before the screen suddenly shuts off.

In this case, it might help to boot your Mac up in safe mode.

To do this, press your Mac's power button. Immediately, press your Shift key, holding it down. Keep your finger on the Shift key until the login screen appears.

Once you've done all this, your computer will be running in safe mode. In this state, the computer runs some diagnostic tests, after which it will boot up your macOS in a stripped-down version.

Only the basics of your computer will load. The Mac won't load any extra hardware features, customs fonts, or startup apps.

If your Mac is able to boot up when it's in safe mode, you can undo some of the recent changes that potentially caused the problem. You might have to remove hardware, disable some startup items, or uninstall any new apps.

Then, if any of these were what caused the issue, you should be able to turn your computer back on the normal way.

5. Reset the SMC

Sometimes, resetting your Mac or Macbook's SMC (System Management Controller) can make it possible to start your computer back up again. This part of your computer manages many of your Mac's basic functions, including your battery and keyboard.

Most importantly, it manages the functioning of your power button when you press it.

Keep in mind that resetting your Mac's SMC can be used to solve many problems you may be having with your computer, not only the issue of your Mac or MacBook not turning on.

For example, if your MacBook doesn't wake up when you open it up, you could use the resetting the SMC strategy.

Resetting the SMC on your computer varies depending on what type of Mac or Macbook you have.

Desktop Mac

If you have a desktop Mac, you first have to unplug the power source from the computer. Wait 15 seconds. Then, plug the power source back into the computer. Next, Wait at least 5 seconds. Finally, restart your Mac to see if the SMC reset worked.

MacBooks with T2 security chip

If you have a MacBook with a T2 security chip, then you need to hold three different keys at the same time for seven seconds. These keys are the right Shift key, left Control key, and left Option key (or Alt key).

While you're pressing these three keys, you also need to press the power button, keeping it held down for an additional seven seconds.

Once you've done this, release the keys you've been pressing. Wait for a few seconds. Then, restart your MacBook or MacBook Pro.

MacBooks that don't have removable batteries

If you have a MacBook that doesn't have removable batteries, then you need to hold three keys at once for ten seconds. These are the Control, Option (Alt), and Shift keys. While doing this, you also have to press the Touch ID/ power button.

After the ten seconds have passed, release the keys you've been pressing. Then, restart the MacBook.

Older MacBooks that have removable batteries

Finally, if you have an older MacBook that has a removable battery, you first need to take out the battery. Then hold down the power button. Do this for five seconds. Next, put the battery back into your MacBook. Finally, restart your MacBook and see if it turns on.

6. Reset the NVRAM (or the PRAM)

Sometimes, resetting your computer's non-volatile random access memory (NVRAM) can help you get your Mac or MacBook to turn back on. This part of your computer is part of its memory. It stores certain settings that your Mac needs quick access to.

If you have an older Mac, you'll be resetting the perimeter RAM (PRAM). However, the way of doing this is the same. Here's what you do.

Press down your Mac or Macbook's power button. Then, immediately hold down four keys: the R, P, Command, and Option (Alt) keys.

Keep these keys pressed down for about 20 seconds. Your Mac may appear to be restarting, but this isn't a reason to lift your fingers up. Keep them where they are even if this happens.

If you hear the startup sound, don't release the keys. Only do this after you've heard the sound a second time.

Keep this in mind: if your Mac has a T2 chip, don't release the keys until the Apple logo has disappeared the second time.

If your Mac or MacBook restarts, you might notice that some of its basic settings like volume level or time zone need to be adjusted.

7. Run Apple Diagnostics

Hopefully, your Mac is turning on by now. However, if it isn't, then you should use the Apple Diagnostics tool. With it, you can find out if there are any hardware issues going on with your computer. Apple Diagnostics will help you identify problems and find solutions.

These solutions will be either fixes or support options available to you.

To use Apple Diagnostics, there are several steps you need to take. First, disconnect any external devices that aren't necessary (your printer, for example).

However, you can keep your monitor, mouse, and keyboard plugged in if you need to.

Next, press your computer's power button. Then, press and hold down the D key. Don't take your finger off it until a screen comes up asking you to choose a language.

Choose a language. Then, Apple Diagnostics will run. After a few minutes, you'll get the results. They will help you know what fixes to use or what type of support you need.

8. Disable the 3rd party drivers

If you are running macOS Big Sur, disabling the 3rd party drivers may solve your Mac or MacBook not booting up problem.

9. Run First Aid in macOS Recovery mode
