MacBook Pro Yellow Screen: Why It Looks Yellow and How to Fix It
By Jack RichardsFounder, Sundown
Your MacBook Pro screen looks yellow because one of five things is warming the display: Night Shift is on (and set to maximum warmth), True Tone is adjusting to an amber-lit room, a third-party blue light filter app is running, your color profile is set to a warm preset, or, far less often, there's a physical display issue. The first four are software and take under a minute to fix or configure, while the fifth needs an Apple technician. This guide shows how to work out which one is turning your screen yellow and how to turn it off. It also covers the case where a yellow screen is not a bug at all but a setting people choose on purpose for the evening.
The Five Reasons Your MacBook Pro Screen Looks Yellow
A yellow Mac screen is almost never a hardware defect. By default the display in your MacBook Pro is set to a cool, neutral daylight white, so if it looks yellow, something is shifting it toward warm amber. These are the five causes.
1. Night Shift Is On at Maximum Warmth
Night Shift is Apple's built-in blue light reduction tool. At maximum warmth, the "More Warm" end of the slider, it shifts your display to a warm white, which gives the screen a noticeably warm cast. It turns on according to the schedule you set (usually Sunset to Sunrise), and you can also switch it on by hand from Control Center.
A lot of people turn on Night Shift, forget about it, and then wonder weeks later why their screen looks permanently warm.
2. True Tone Is Adjusting to Your Room Lighting
True Tone uses ambient light sensors to match your display's color temperature to the room around you. Under warm incandescent or candlelight-style bulbs, True Tone shifts your screen warmer, sometimes by enough to notice.
True Tone is not a blue light filter, because it only moves the display in whichever direction your room lighting pulls it. If you work under warm desk lighting, though, True Tone may be part of why your screen looks yellow.
3. A Third-Party Blue Light App Is Running
f.lux, Sundown, Iris, and CircadianShield all change your display's color output. f.lux at its deep orange and Sundown at its deep red both make a display look noticeably warmer, especially next to a factory-calibrated screen.
If you or someone else installed a blue light filter app and forgot about it, it may be running quietly in the menu bar, possibly on a schedule.
4. A Custom Color Profile Is Applied
macOS lets you apply custom display color profiles through System Settings → Displays → Color Profile, and a "Warm" profile or a manually calibrated one can shift the display toward yellow. This is less common, but it turns up often when a colorist or photographer has calibrated the display for a particular workflow and chosen a warm reference white.
5. A Physical Display Issue (Rare)
MacBook Pro displays can develop a real yellow tint from display delamination or from backlight or panel aging. Physical yellowing is almost always confined to one part of the screen, such as a corner, an edge, or a band, and it does not go away when you change software settings. So if your yellow tint is even across the screen and responds to software changes, it's software, and if it's localized or ignores your settings, it's hardware.
How to Fix a Yellow MacBook Pro Screen
To remove a yellow tint on your MacBook Pro, work through these fixes in order: turn off Night Shift, check True Tone, quit any blue light filter apps, and reset your color profile to the default. Each one takes under 30 seconds.
Fix 1: Disable Night Shift
Open System Settings → Displays → Night Shift. If Night Shift is on, set the schedule to "Off". You can also open Control Center (top-right of your menu bar), click the brightness slider, and look for the Night Shift toggle there.
If your screen goes back to normal straight away, Night Shift was the cause. You can leave it off entirely, or set it to come on only after 10 PM at a lower warmth setting.
Fix 2: Disable True Tone
Open System Settings → Displays and uncheck True Tone. Your screen will snap to a fixed white point whatever the ambient light, and most people find it looks cooler and slightly bluish compared with True Tone on, because their eyes had quietly adjusted to the warmer color.
Fix 3: Quit Any Blue Light Filter Apps
Check your menu bar for app icons from f.lux (a small sun or moon symbol), Sundown (a sun icon), Iris (a blue eye), or anything similar. Click the icon and look for "Quit" or a toggle that turns the filter off. f.lux has no Dock icon at all, so if you can't find it, see where f.lux lives in the menu bar. You can also open Activity Monitor (search for it in Spotlight) and look for these apps in the process list.
Fix 4: Reset Your Color Profile
Open System Settings → Displays → Color Profile and select Color LCD, or whichever factory-default profile belongs to your display model, which usually sits at the top of the list.
Fix 5: Contact Apple (for Physical Issues)
If the yellow tint is still there after you've turned off every software setting, and it's localized to one area of the screen, book an appointment at an Apple Store or contact Apple Support.
When a Yellow Screen Is the Right Choice
This part surprises people, but if you use your MacBook Pro in the evening, some screen warmth is not a glitch to get rid of.
Ostrin et al. (2017) found blue-blocking lenses raised nocturnal melatonin ~58% in healthy adults, who also slept ~24 minutes longer (Ophthalmic & Physiological Optics). A yellow screen works on a similar principle to amber-tinted glasses, in that both cut the 460nm light reaching your eyes, although that study tested lenses and not a screen.
So the useful question is less "how do I remove the yellow?" and more "how yellow should it be?"
How Yellow Can Each Option Go?
The built-in option stops well short of how warm a third-party app can take the screen.
| Method | Color Temperature | Yellow Appearance | Cost |
|---|---|---|---|
| Night Shift (max warm) | A warm white | Mild yellow, like warm indoor lighting | Free (built-in) |
| f.lux (warmest) | A deep orange | Deep orange | Free |
| Sundown (warmest) | A deep red | Deep red | $4.99/mo, $39/yr or $79 lifetime |
Night Shift at its warmest looks warm, about the color of a standard incandescent bulb, but it is still a warm white rather than amber.
f.lux at its warmest goes noticeably deeper. Your screen will look orange and white areas will turn a warm amber.
Sundown goes down to a deep red, where the blue channel is turned off. The result is a deep red display that looks odd if you're not used to it. It also has a flicker-free mode, which holds the backlight at full power and dims through the gamma table instead, so dimming does not rely on the backlight's PWM. An anti-dithering mode is aimed at the dithering artifacts on Apple Silicon models (here is how to turn off dithering on a Mac).
Configuring the Right Warmth Level for Your Workflow
The practical approach is to keep your display at normal calibration during work hours and move to deliberate warmth after a set point in the evening, usually sunset or the time you stop doing color-critical work.
If you want to keep it simple and free, Night Shift on "Sunset to Sunrise" at maximum warmth is a reasonable place to start. It will make your screen yellow, which is what it should do. Its limit is that it stops at a warm white, which matters if you're working until midnight and want the screen warmer than that.
If you care about sleep quality and spend a lot of time on your MacBook after 8 PM, think about scheduling the change in two stages. Use Night Shift at sunset for the mild shift, then a deeper filter like Sundown at 9 or 10 PM, picked from the menu bar or set on a custom schedule by time of day. Turn Night Shift off when you use Sundown, because two apps changing the display color at once give unpredictable results.
Yellow Screen Myths Worth Clearing Up
"Dark Mode removes the yellow tint." No. Dark Mode changes the color of interface elements, so light backgrounds become dark and dark text becomes light, but it does not change the spectral output of your display. A screen that is yellow in Light Mode is just as yellow in Dark Mode.
"Lowering brightness fixes the yellow." No. Lowering brightness reduces total light intensity but does not change which wavelengths are emitted, so your screen at 20% brightness still emits the same proportion of 460nm light, only less of everything.
"An external monitor will look normal." That depends entirely on the external monitor's settings.
When to Call Apple About a Yellow Screen
There are three situations where it's time to contact Apple support. (1) You've turned off Night Shift, True Tone and all third-party apps and reset your color profile, and the yellow tint is still there. (2) The yellow is confined to one corner or edge of the display. (3) The tint looks greenish-yellow instead of warm amber, which points to a different issue from warmth.
The Short Answer
If you want to keep a warm screen on purpose, what's left to decide is how deep to go. Night Shift stops at a warm white, and Sundown goes down to a deep red. Where you land between them depends on how late you work and how much your sleep matters to you.
