A blank screen may appear multiple times when you turn on a Mac computer. Now, this blank screen can be of any one of the following colours: black, blue, and grey. However, your Mac may boot but it seems like the screen is stuck on a blank display.
For example, your Mac screen hardly shows any sign of activity or response even when you press a key or try moving the pointer. Let’s not panic and find out what you can do to bring your Mac out of such a blank screen situation, as recommended by a MacBook repair Dubai expert.
How to Fix a Mac Blank Screen After Booting Up?
Rather than directly jumping towards the fixes, it’s better to investigate the probable reasons why your Mac starts with a blank screen. According to a Macbook repair Dubai shop, your MacBook screen can become blank after the OS boots due to the following reasons:
- Your MacBook lacks sufficient power to stay up.
- Otherwise, your Mac might have updated to a newer version of macOS. New updates can make you face problems with compatibility along with bugs, large disk space consumption, and more.
- On the other hand, loosely connected cables between your Mac and the external monitor can cause the same issue. So, check the cables if you have plugged an external monitor into your Mac.
- Third-party apps can also cause disturbance to the screen and force it to stay blank.
- Contacts between your Mac’s hardware and firmware might be poor. Damaged, dusty, and loose contacts between hardware and firmware might prevent your Mac from starting normally.
- Motherboard failures are another reason the screen is blank.
Let’s now move on to the proven fixes for a blank screen Mac:
1. Test the Power
Are you sure that your Mac draws power from the connected outlet? Chances are that your MacBook had a minimum energy to turn on and it couldn’t stay up and running further. So, a MacBook repair in Dubai recommends securely connecting the power supply to your Mac.
After turning it on, your Mac should produce noise due to cooling fans and hard drives. So, listen closely if you can listen to any such noises once your Mac powers on. Make sure you charge your Mac for 10 minutes straight before turning it on.
If the problem persists, we insist you move on to the next fixes.
2. Detach connected Peripherals
Too many accessories connected to your Mac at the same time might interfere with the display settings. Hence, a MacBook repair service near me suggests unplugging all the peripherals from your Mac, such as:
- Phones
- Printers
- Flash drives
- External hard drives, etc.
However, don’t remove your Mac’s power adapter from it. See if your Mac boots successfully. Or else, keep reading the guidelines.
3. Restart Your MacBook
Have you started losing patience? Try a quick restart formula to improve your Mac screen’s responsiveness. So, turn off your Mac and turn it back on to see if you get rid of the problem. Here’s what you need to follow:
- Hold your Mac’s Power button for 10 seconds or so until the computer turns off. If your Mac has a Touch ID instead, hold the Touch ID and the device will shut down.
- Now, press your Mac’s Power button promptly to restart your device.
Does the screen remain blank? Don’t worry; we still have more solutions left.
4. Modify Your Mac’s Screen Brightness
MacBook repair services in Dubai are pretty confident that too-low brightness can make your Mac screen blank. Chances are that you have pressed the brightness keys and it made your screen dimmed down. Or, whoever has done this unknowingly, you should adjust the brightness of the screen and see if the situation improves.
Hence, try increasing your Mac screen brightness using the F1 and F2 buttons from the keyboard. Hopefully, the light comes back to the screen. Otherwise, continue with the steps mentioned below.
5. Try a macOS Recovery
MacBook repair Dubai professionals suggest starting up from a macOS Recovery if the blank screen doesn’t disappear. The following steps are for those who own a Mac with Apple silicon:
- Hold your Mac’s power button for 10 seconds to ensure the device is turned off.
- Afterwards, you need to press and hold the power button. As you force restart your Mac, your device will display startup options. Release the power button once you can see Options on your Mac screen.
- Next, click Options followed by the Continue button that resides just below the Options.
- The Utilities window must show up by now. Navigate to Disk Utility and click on it to repair the startup disk.
- Now, restart your Mac computer and see if the blank screen returns.
However, the above steps won’t work for a Mac with Intel processors, as confirmed by a MacBook repair service in Dubai. For them, you need to use the following guidelines:
- Hold your Mac computer’s power button for 10 seconds straight. This should turn off your Mac.
- Now, press and promptly release the power button to turn on the device. As soon as you press and release the power button, hold the Command and R buttons together. Don’t let go of them until you notice a spinning globe or Apple icon on your Mac screen.
- Afterwards, the screen will prompt you to choose a network from the Wi-Fi menu. On the other hand, you can connect an Ethernet or network cable to your Mac.
- Next, look for the Utilities window and use Disk Utility so that you can repair your startup disk.
- Finally, you can restart your Mac.
6. Enter Safe Mode
Boot up your Mac computer in Safe Mode as it allows your device to start without launch agents starting. Thereafter, your Mac can launch without handling complex apps and interfering services that might prevent your system from displaying properly.
Here’s how you can boot your Mac into Safe Mode:
- Turn off your Mac and wait for 20 seconds or so.
- After that, press and release the power button immediately to turn the device on. As soon as you release the power button, hold the Shift key.
- You should let go of the Shift key when the login window pops up.
- Now, check the Safe Boot option from the top-right corner of the screen and click on it. However, your system may prompt you to log in twice.
On a related note, your Mac can take longer to boot into Safe Mode depending on its variant or the requirement of logging into the device. On top of that, the diagnostics can take time to complete.
After your Mac successfully boots into Safe Mode, you can restart the system and launch it through a normal startup. The blank screen should not come back.
7. Reset PRAM or NVRAM
Chances are that your Mac is stuck to some kind of technical issue if the blank screen doesn’t disappear from your computer’s display. A MacBook repair service near me suggests resetting your Mac’s PRAM and NVRAM components to make things right.
The are small memory partitions that save settings such as display resolution and volume control. If problems come up with them then they require resetting. However, a Mac with an Apple silicon will automatically reset its memory partitions with a restart. Whereas Mac computers with Intel chips need the following steps to reset their PRAM or NVRAM:
- Turn off your Mac by holding its power button.
- After a while, turn it back on and immediately hold the following keys from the keyboard: Option, Command, P, and R. The machine must be booting while you press and hold these buttons.
- Only release these keys when you can hear a startup chime from your Mac.
Resetting your Mac’s PRAM or NVRAM might result in losing some important settings, as reminded by a MacBook repair service in Dubai. If your Mac’s screen doesn’t stay blank anymore, don’t forget to adjust your display, date and time, and disk options if they seem to be different from what they should be.
8. Reset Your Mac’s System Management Controller
MacBook Repair Services Dubai experts recommend resetting the System Management Controller or SMC to discard the chances of a blank screen. The SMC component of your Mac is responsible for controlling components such as the keyboard, display, temperature, fans, etc.
Let’s check out how you can reset your Mac’s SMC:
- Start by turning off your Mac and unplugging your system from the power supply.
- After 15 seconds or more, you can plug the system back into its power supply.
- Don’t power on your Mac yet. Hold the Shift, Option, Control, and the power buttons altogether.
- Let go of these keys when your Mac boots.
Reinstall macOS: The Final Resort
Does your Mac screen still stay blank? It’s high time you consider reinstalling macOS. You can contact a MacBook repair Dubai shop or Apple Support to proceed further. You can either reinstall the same macOS product. Otherwise, opt for a new macOS and install it on yur Mac computer.
