Mac Black Screen Issues: Causes and Solutions

Resolve Mac black screen issues with simple troubleshooting or professional help for software glitches, hardware problems, display issues, or macOS updates.


Encountering a black screen on your Mac can be incredibly frustrating. One minute you’re plugging along on an important project, and the next—nothing but darkness. Unfortunately, blank and black screens are a common issue that many Mac users face. The purpose of this blog post is to explore what causes these pesky black screens on Macs and provide some practical solutions to get your display back up and running.

Common Causes

There are a few common culprits when it comes to black screen issues on Macs:

  • Software glitches from a system update or new app installation can sometimes trigger graphics issues that lead to black screens.
  • Hardware problems like an ageing graphics card, faulty display cable, or bad logic board can also result in black screens with no obvious cause.
  • Issues with the display itself, like dead pixels or backlight failure, may show up as black screens.
  • Incompatible macOS updates can cause problems with graphics drivers and screens.

As you can see, black screens generally stem from software crashes, hardware malfunctions, display failures, or OS issues. The good news is that with some targeted troubleshooting, you can usually resolve them.

Common Causes of Mac Black Screen

Software glitches are a common cause of Mac black screen issues upon startup. Minor bugs or corrupted files can prevent the system from booting properly, leading to a blank display. Resetting NVRAM or reinstalling the operating system often resolves these software-related black screens.

Faulty hardware components like the logic board, graphics card, or display cables can also trigger a black screen on Mac. If the Mac turns on but the screen remains black, it likely indicates a hardware failure. Getting assistance from Apple Support or an authorised service provider is recommended in such cases.

Display problems with the LCD panel, backlight fuse, or display connectors can result in a black screen even when the Mac is on. Issues like cracked screens, faulty backlights, loose connectors, etc. must be checked by a professional to identify and replace any damaged display components.

Incompatible macOS updates are another potential culprit behind black screen problems. An update may not be fully supported by the Mac’s hardware or have bugs that cause display issues. Booting into Safe Mode after an update and installing the latest macOS patches helps resolve such problems.

Troubleshooting Mac Black Screen

A black screen on your Mac can be incredibly frustrating. Before taking more extreme measures, try restarting your Mac to resolve any minor software glitches that may be causing the issue. Simply shut down your computer and turn it back on after a few seconds. This refresh often fixes temporary display problems.

Boot Into Safe Mode

If a restart doesn’t work, boot into Safe Mode. Safe Mode loads only essential macOS files and can determine if third-party software is the culprit behind your black screen. To use Safe Mode, restart your Mac and immediately press and hold the Shift key. The Apple logo will appear with the words “Safe Boot” to confirm you’re in Safe Mode.

Check Connections

It’s also important to check that all cables and connectors related to your display are properly attached. This includes power cables, Thunderbolt, HDMI, and any adapter cables. Reseat each cable at both ends to ensure a snug fit. If your Mac notebook uses the built-in display, make sure it hasn’t been closed and entered sleep mode.


Resetting your Mac’s NVRAM and PRAM can often resolve software-related display issues that cause black screens. To do this, shut down your Mac. Then restart your computer and immediately press the Command, Option, P, and R keys together. Hold them down until you hear the startup chime a second time. This will wipe and restore those settings to their defaults.

Professional Assistance

When dealing with a black screen issue on your Mac, seeking professional assistance can be key to resolving the problem efficiently. Apple Support should be your first stop for hardware-related black screen problems. Their technicians have extensive experience troubleshooting Mac hardware and can help diagnose issues like failed components or connections.

Certified Repair Centers

For complex black screen problems that Apple Support cannot resolve, seeking help from an Apple Authorised Service Provider is recommended. These certified Mac repairs have the training and resources to address intricate hardware and software issues related to the black screen.

An authorised Mac repair shop can troubleshoot components like the logic board, display cables, graphics card, and more. They also have access to advanced diagnostic tools and genuine Apple parts for replacements when necessary. While an authorised service provider may cost more than DIY troubleshooting, they save you time and give you peace of mind from a professional repair.

In summary, encountering a black screen on your Mac can be incredibly frustrating, but there are usually identifiable causes behind the issue. As we explored in this blog post, software glitches, hardware failures, display problems, and macOS updates may all trigger a black screen.

Before panicking, try some basic troubleshooting steps like restarting your Mac, booting into Safe Mode, ensuring secure connections, or resetting NVRAM. If the issue persists, it likely requires professional assistance. Hardware issues in particular may need a trip to the Apple Store or an authorised service provider.

While a black screen can disrupt work, there are solutions. With methodical troubleshooting and sometimes technical support, Mac users can get their displays functioning properly again. The key is not to ignore the issue and instead take proactive measures to diagnose the cause.

By understanding the common culprits behind black screens and learning the best practices to resolve them, Mac users can minimise downtime and frustration when problems emerge. With the right approach, you can get your Mac’s display shining brightly once more.
