Boost · Beyond the maximum
Make your Mac brighter than macOS allows.
Bright sunlight and window glare can overpower the standard brightness range on a MacBook Pro. LUMEL's Boost mode uses the EDR headroom a supported XDR display reports, and unlike one-trick boosters it can also dim below the minimum at night. Free to download, no account, no data collected.

Why your Mac won't go bright enough
MacBook Pro brightness specifications vary by generation. Earlier XDR models expose a lower standard SDR range than newer models, while supported displays retain additional EDR headroom for HDR and bright viewing conditions.
That's fine indoors. Outdoors, on a train, or next to a bright window, the cap leaves the screen looking grey and unreadable while the panel sits there with brightness to spare.
LUMEL Boostopens that reserved headroom using Apple's public Extended Dynamic Range rendering — no private APIs, no system hacks — so the brightness your hardware already has becomes brightness you can actually use.
How to make your Mac brighter

Open it from the menu bar
LUMEL lives in your menu bar. Click the icon to open the slider.

Switch to Boost
Tap Boost — the daylight direction that goes past the macOS maximum.
- 4
Push past the maximum
Drag the slider up and the screen jumps brighter toward its peak. Compare boosts the left half free; full-screen boost is a one-time $2.99 unlock.
Boost requires an EDR/XDR display with available headroom. Eclipse works on any Mac display supported by LUMEL, including displays that cannot Boost.
One app for brighter and darker
Boosting for sunlight is only half of it. LUMEL also has Eclipse mode — dim your Mac below the macOS minimum for dark rooms and late-night reading. Day and night, one menu-bar app, one tap.
Questions, answered
Can you make a MacBook brighter than its maximum?
Yes, on supported hardware. LUMEL's Boost mode uses Apple's public Extended Dynamic Range path and only the headroom the display and macOS report as available. The result depends on the exact Mac, power state, temperature, and ambient conditions.
Why is my MacBook screen so dim in direct sunlight?
Glare can overpower the standard brightness range. That range varies by MacBook Pro generation and conditions, so it is not always 500 nits. On supported XDR models, Boost can use EDR headroom that macOS makes available.
Is boosting brightness safe for my Mac?
Your Mac's display firmware enforces its own thermal limits, so LUMEL can't drive the panel beyond what the hardware already permits. The mini-LED and LCD displays it supports don't suffer OLED-style burn-in. Sustained brightness runs warmer, so LUMEL is built for bursts and includes an optional auto-off timer and battery-aware safeguards.
Does a brighter screen drain the battery faster?
A brighter display uses more power, yes. That's why LUMEL lets you set a battery threshold from 10% to 50% — below it, boost switches off automatically — and Low Power Mode disables boost too, so it never quietly drains your day.
Which Macs can boost?
Displays that report extended dynamic range headroom: the 14- and 16-inch MacBook Pro (Apple silicon), Pro Display XDR, and Studio Display XDR. On other Macs the app still opens, but the boost controls stay inactive until a compatible display is connected — Eclipse dimming, however, works on any Mac.
