Which Macs does Solis work with?
Any MacBook Pro with an XDR display (M1 Pro/Max or newer, 14"/16"), plus the Pro Display XDR and Studio Display XDR. These panels can reach ~1000–1600 nits, but macOS caps everyday content far lower — Solis unlocks the rest.
Is it safe? Will it drain my battery or overheat my Mac?
It's designed to be. macOS itself enforces a hard limit on the panel's temperature and pulls brightness back long before anything could be harmed — Solis works within that, and goes further: it's the only app that also reads the panel's own thermal signal and eases the boost off early, tapers on battery, and brightens only when ambient light calls for it. Honest note: running any display at high brightness all day uses more power and, over years, gently ages the LEDs (true of every boosting app) — so Solis backs off automatically when it doesn't need to be bright, which is exactly the point.
Is it safe? Why isn't it on the App Store?
Solis is signed and notarized by Apple, so it installs cleanly with no scary warnings. Its smart features (the light sensor, the panel's thermal data, the brightness keys) need capabilities the App Store sandbox doesn't allow — which is exactly why Lunar, BrightIntosh, BetterDisplay and f.lux are all direct downloads too.
How is this different from Night Shift?
Night Shift only warms the screen, on a schedule, and can't combine with brightness. Solis warms at your real local sunset, goes warmer, and pairs it with brightness — bright and neutral by day, dim and warm at night. It'll even turn Night Shift off so they don't stack.
Does it mess with my colors?
The boost is a real backlight increase mapped into the display's HDR headroom, so color stays accurate — not a dim, washed-out overlay. You can push further into a clearly-marked "maximum" zone if you ever want raw brightness over perfect color.
