A User-Friendly Guide to Resolving Common Macbook Screen Glitches

Apple’s MacBooks are renowned for their sleek design and reliability. However, even the most well-crafted devices can encounter screen glitches from time to time. Whether it’s your MacBook screen flickering, freezing, or strange artifacts appearing, these issues can be frustrating. 

Nonetheless, before you panic or rush to the nearest repair shop, many common MacBook screen glitches can be resolved with a few simple troubleshooting steps. In this guide, I’ll walk you through some of the most prevalent steps to fix common Macbook screen issues, empowering you to get back to using your computer without interruption.

Identify the Problem

Before you go hauling off trying random fixes, take a beat actually to observe what is unfolding on your screen. Is it flickering sporadically like a buggy plasma globe? Or displaying annoying visual artifacts straight out of an ancient DOS game? Maybe the screen just point-blank refused to illuminate, leaving you with a terrifying void rupture. Whatever the particular problem, note it – that way you can properly perform troubleshooting based on a specific issue. 

Check for Software Updates

I know updating software is about as exciting as watching CGI render farms on a smoggy day. But stick with me here – it’s an important first step that way too many people gloss over in their haste. Outdated software and drivers can cause all sorts of weird conflicts and compatibility snafus with your Mac’s display output. So take 10 minutes, open up that System Preferences > Software Update panel, and let’s download any and all available patches from the Apple overlords. Who knows, it may be a simple fix!

Check for Overheating Issues

Heat can definitely cause display glitches and other graphics wonkiness on laptops. If your MacBook is running hot to the touch, especially around the display hinge area, it could be a sign of overheating. Make sure you’re using it on a solid, ventilated surface (not on blankets/pillows), and see if manually ramping up your fans using an app like Macs Fan Control helps keep temps down. Dust buildup inside can also choke airflow, so a compressed air dusting may be due.

Adjust Display Settings

If the updates didn’t magically resolve your screen’s existential crisis, it’s time to dig into those dusty Display Preferences. Sometimes your resolution, brightness, or scaling settings can get…let’s say, eccentric, and just need a little tough love. Fire up that pane, toggle some settings, try different resolutions. See if you can trigger some kind of reset. You can even option-click that “Scaled” box to zap its memory. It’s worth a rapid-fire couple of minutes of just mashing settings together before escalating further.

Restart Your MacBook

I know, I know – a total system reboot feels like the IT equivalent of percussive maintenance. But there’s a reason this unstunning maneuver has stayed in the playbook since the days of elevating computers to work the bugs out. By fully power-cycling your Mac, you clear out any weird temporary files or frozen app states that could be throwing a wrench in your display. A clean restart is computing 101!


If a traditional restart didn’t succeed in exercising your MacBook’s screen problems, it’s time to try an even deeper system flush. The NVRAM and PRAM handle a bunch of funky low-level system settings related to displays and such. By resetting them (hold Command + Option + P + R at startup until you hear two chimes), you unceremoniously dump any potential gremlins that could be messing with your screen. It’s almost like a factory reset…but without that sinking feeling of data loss!

Run Apple Diagnostics

If software-related solutions prove ineffective, hardware issues may be the culprit. That’s where Apple’s built-in hardware diagnostics come in clutch. This tool of blinking lights and cryptic codes can theoretically sniff out any component faults – whether it’s a borked logic board, busted GPU, or faulty display panel. Sometimes those results can at least steer you in the right direction for what part may require a trip to the neighborhood technician.

Check External Connections

But perhaps we’re getting ahead of ourselves here. If you’ve got external displays, dongles, or adapters attached to your MacBook’s I/O ports, check those connections to ensure they are not the problem. Loose cables, gunked ports, or incompatible dongles can cause crazy display corruptions and outages. You’d be amazed how often bum cable management has been the culprit all along.

Use Apple’s Support Resources

After exhausting all those steps, sometimes you just need to call in the experts. Whether it’s a Genius Bar appointment or tapping Apple Support online/by phone, describing your ongoing issue could lead to additional insight. They may have you run special diagnostic tools or point you towards an authorized repair if it’s looking like a hardware failure.


Addressing common MacBook screen glitches doesn’t have to be daunting. By following the user-friendly steps outlined in this guide, users can navigate through troubleshooting with confidence. From simple software updates and display adjustments to more advanced diagnostics and seeking professional assistance when needed, this guide empowers users to tackle screen glitches efficiently. With patience and persistence, users can resolve issues and enjoy uninterrupted productivity with their MacBooks.
