SunShift is a macOS menu bar app for adjusting Night Shift intensity without opening System Settings.
Night Shift warmth is one of the few display settings I actually want to tweak throughout the day, but Apple hides it behind too many clicks in System Settings. I built SunShift to make that adjustment feel like a tiny native control in the menu bar instead of a trip through preferences.
brew tap scasella/tap
brew install --cask sunshiftbash build.sh
open SunShift.app- Launch
SunShift.app. - Click the sun icon in the menu bar.
- Toggle Night Shift on or off.
- Drag the intensity slider or click a preset:
25,50,75, or100.
sun.max.fillmenubar icon- Compact Liquid Glass popup
- Night Shift on/off toggle
- Live intensity slider
- Four quick presets:
25,50,75,100 - Graceful unsupported state if the private bridge is unavailable
- No Dock icon
swift build
swift test
bash build.sh- macOS 26+
- Swift 6.2+
- Xcode Command Line Tools
SunShift is a local utility that loads CBBlueLightClient from /System/Library/PrivateFrameworks/CoreBrightness.framework at runtime. If Apple changes or removes that class, the app falls back to an unsupported state instead of crashing, but it is not App Store-safe.
