It’s a ghost. You’re working on a late-night project, the room is dim, and you notice a faint, shimmering outline of the "Escape" key or the volume slider even though you’ve switched to a different app. That’s touch bar burn in. It isn't just a minor annoyance; for many MacBook Pro owners who bought into the 2016–2022 era of Apple’s design, it’s a permanent reminder of a hardware experiment that didn't quite land where it was supposed to.
Most people assume "burn-in" is something that only happens to cheap TVs or those display units at the back of a Best Buy. But the Touch Bar is an OLED strip. OLED stands for Organic Light Emitting Diode. The "organic" part is the kicker because it means the material literally decays over time as it’s used. When you keep the same static icons—like that Siri button you never touch or the brightness toggle—lit up for 12 hours a day, the pixels wear out unevenly.
Honestly, it’s kind of ironic. Apple pushed the Touch Bar as the future of dynamic input, yet its biggest technical flaw is caused by things staying exactly the same.
The Science of Why Pixels Get Stuck
If we're being real, the term "burn-in" is a bit of a misnomer. Nothing is actually on fire. What’s happening inside that tiny sliver of glass above your keyboard is cumulative sub-pixel degradation. Every OLED pixel is made of red, green, and blue elements. Blue is the troublemaker. It has the lowest luminous efficiency, which basically means it has to be driven harder (with more voltage) to match the brightness of red and green.
Because it’s pushed harder, it dies faster.

When you see a "ghost" image of the Play/Pause button, you’re seeing the ghost of those overworked blue sub-pixels. They can't keep up anymore. This isn't a software bug. You can’t "update" your way out of physical hardware decay, although Apple did try to mitigate it with some clever software tricks in later versions of macOS.
The 13-inch and 15-inch (and later 16-inch) MacBook Pros from that era used Samsung-manufactured OLED panels for the Touch Bar. Samsung knows their stuff, but these strips were thin. Really thin. And they sat right on top of one of the hottest parts of the laptop: the bridge between the CPU and the cooling fans. Heat is the enemy of OLED. When your Intel i9 processor is screaming at 100°C while you’re rendering a 4K video, that heat is soaking directly into the Touch Bar’s adhesive and organic compounds. It’s a recipe for disaster.
How to Tell if You Actually Have Touch Bar Burn In
Don’t panic yet. Sometimes what looks like burn-in is actually just "image retention."
Here is the difference: image retention is temporary. If you leave a static image on an OLED for an hour, the ions get a bit lazy and "stick" for a few minutes. If you change the screen or turn it off, the ghosting eventually fades away. True touch bar burn in is permanent. If you’ve restarted your Mac, reset the NVRAM, and you still see the ghost of the Safari search bar while you’re watching Netflix, it’s permanent damage.
Want to test it?
Open a completely white image and drag it so it’s near the top of your screen, then use a tool like "BetterTouchTool" to turn the Touch Bar completely white. If you see dark patches or yellowed shapes where buttons used to be, that’s the pixel wear showing through. On the flip side, some users report "stage light" effects or flickering. That’s usually not burn-in; that’s a failing ribbon cable, often dubbed "Flexgate’s little brother."
Real-World Fixes (And Why Most Don't Work)
You'll see a lot of "advice" on Reddit and MacRumors about how to fix this. Let's sort the wheat from the chaff.
- Jiggling the pixels: Some people suggest running a "pixel refresher" video—basically a seizure-inducing loop of changing colors. On a phone, this might help minor retention. On a Touch Bar? It’s mostly useless because the screen is too small and the damage is usually too far gone.
- The "Black Hole" Strategy: This is my favorite. If you use an app like Pock or BetterTouchTool, you can actually customize the Touch Bar to be completely black when not in use. Since OLEDs turn pixels completely off to produce black, you’re saving the "life" of the organic material.
- The Hardware Swap: Here is the bad news. You can't just "replace" the Touch Bar easily. It’s glued into the top case. If you take it to Apple, they will often tell you that the entire top case—keyboard, battery, and metal housing—needs to be replaced. If you’re out of warranty, you’re looking at a bill of $400 to $700.
Is it worth it? Probably not for a machine that’s already five years old.
The Weird Connection to Heat and Fan Curves
There is a very specific group of users who see touch bar burn in way more than others: the "clamshell mode" crowd.

If you use your MacBook Pro closed, hooked up to an external monitor, the heat dissipation changes. The vents on those models are located near the hinge, right by the Touch Bar. With the lid closed, the heat is trapped against the display and the Touch Bar strip. I’ve seen boards where the Touch Bar started delaminating or showing severe discoloration specifically because the user was pushing the GPU hard while the laptop was shut.
If you're going to use an older MacBook Pro in clamshell mode, for the love of your hardware, use a stand that allows for better airflow. Or better yet, keep it cracked open a few inches.
Prevention is the Only Real Cure
Since you can't really "fix" a burnt pixel, you have to be proactive.
First, go into System Settings and set the Touch Bar to "Show Expanded Control Strip" or "App Controls" but, more importantly, set it to "Turn off after X seconds." By default, the Touch Bar stays lit as long as your main screen is on. That’s dumb. Change it so it goes dark after 60 seconds of inactivity.
Second, vary your usage. Don't leave the same custom "mute" button in the same spot for three years. Move your icons around every few months. It sounds like a chore, but it’s the only way to ensure the sub-pixels wear down at an even rate. It's like rotating the tires on your car. If you don't do it, you're going to end up with one very bald tire and three good ones.
The Legacy of the OLED Strip
Apple finally killed the Touch Bar with the M1 Pro and M1 Max MacBook Pros in 2021 (mostly). The 13-inch M2 MacBook Pro kept it around for a victory lap, but the writing was on the wall. Why? Because pro users wanted physical keys, but also because the long-term reliability of a secondary OLED display in a high-heat environment was a nightmare for Apple’s support teams.
We’re now entering the "vintage" era for the original Touch Bar Macs. As these machines hit the secondary market on eBay or Swappa, touch bar burn in is becoming a standard check-item, right alongside battery cycle count and "butterfly" keyboard double-typing issues.
If you’re buying a used Mac, ask the seller for a photo of the Touch Bar at max brightness showing a solid color. If they hesitate, there’s probably a ghost in the machine.
Actionable Steps for Current Owners
If you’re currently staring at a faint ghost of a Volume icon, here is exactly what you should do to stop it from getting worse and manage the damage you already have:
- Install BetterTouchTool (BTT): This is the gold standard. It allows you to set a global "sleep" timer for the Touch Bar that is independent of your main screen. You can also set it to turn off the bar entirely when specific apps are open.
- Lower the Brightness: There isn't a dedicated slider for Touch Bar brightness in macOS (standard Apple move), but certain third-party scripts can force it into a lower power state. Less voltage equals less heat, which equals slower decay.
- Check for Recall Programs: While Apple never launched a specific "Touch Bar Burn In Program," they did have programs for "Keyboard Service" and "Display Backlight." Sometimes, if you have a failing keyboard and you're eligible for that program, the entire top case replacement includes a brand-new Touch Bar for free. It’s worth checking your serial number on Apple’s support site.
- Embrace Dark Mode: It won't fix the bar, but it reduces the overall light pollution in your workspace, making the ghosting less noticeable during daily tasks.
- Use an External Keyboard: If you're at a desk, use a Magic Keyboard or a mechanical deck. This lets the Touch Bar rest and keeps your hand oils (which can also degrade the coating over years) off the glass.
The Touch Bar was a bold idea that suffered from the limitations of current-gen OLED tech. It’s a piece of tech history now—just make sure yours doesn't become a permanent, glowing piece of history you can't turn off.
