The short answer
You can make your screen brighter than max, but only on certain Macs. The 14-inch and 16-inch MacBook Pro and the Pro Display XDR can reach about 1,600 nits. macOS holds the everyday slider far below that ceiling and saves the rest for HDR content. To go past max, you need to open that range. On other Macs, the slider is already at the real limit, and there is no extra headroom to reach.
If you have one of the supported models, MacBrightness opens the full panel system-wide in one tap, for a one-time $5.
Why macOS caps it
Think of it like a car with a speed limiter set below the engine’s real top speed. The hardware is capable. The software governs it.
The mini-LED panels in the 14-inch and 16-inch MacBook Pro sustain around 1,000 nits and can peak near 1,600 for short bursts. macOS uses that headroom for HDR: when you watch an HDR film, the bright parts go all the way up. For everything else, the cap holds.
That cap is why your browser, editor, and desktop look the same indoors and out. The screen works fine; macOS is holding the brightness back.
The built-in tricks, and why they fall short
Before spending anything, two things are worth trying:
- Turn off auto-brightness, True Tone, and Low Power Mode. All three can hold the screen back. Find them in System Settings under Displays and Battery. If any are on, disabling them may recover some brightness you didn’t know you’d lost.
- Play HDR content. Open an HDR video in the TV app or on YouTube. macOS allows the full brightness range for HDR highlights, so the screen will briefly exceed the everyday cap.
The problem with the second trick: it only works for HDR content. Your terminal, browser, and everything else stay at the old ceiling. You’re not past max in any useful sense.

The clean fix: open the whole range
A brightness app for Mac like MacBrightness works differently from the HDR trick. It makes the full range available system-wide, permanently. You press brightness up and the screen keeps going past the old stop. Your browser, editor, PDF, whatever you’re looking at: all of it gets brighter.
It uses the same HDR brightness Apple already sustains for editing, so there are no low-level hacks involved. macOS still pulls back the peak if the panel gets warm.
Which Macs can do this
| Mac | Can go past max? |
|---|---|
| MacBook Pro 14-inch, M-series Pro/Max | Yes |
| MacBook Pro 16-inch, M-series Pro/Max | Yes |
| Pro Display XDR | Yes |
| MacBook Air (any) | No, already at true max |
| MacBook Pro 13-inch / M1 | No, already at true max |
| Intel Mac | No, already at true max |
| Studio Display | No, already at true max |
If your Mac isn’t in the top group, the settings above are your only lever. No app can add brightness a panel doesn’t have.
If you’re not sure whether it will help
MacBrightness opens in Splitscreen Mode: half your screen goes to full brightness for free, the other half stays at the normal cap, side by side. You can see the difference before paying anything. If the gap looks worth $5, one purchase covers the whole screen permanently. If you have a MacBook Air or an older Mac and the mode does nothing visible, you’ll know immediately you’re already at the real limit.
