Automatically disable Night Shift for specific apps on macOS

adamdexter.net  •  Buy Me a Coffee

Night Shift is great for reducing eye strain, but it wreaks havoc on color-critical work. If you use Photoshop, Lightroom, Premiere Pro, DaVinci Resolve, or any other app that depends on accurate color, you've probably been manually toggling Night Shift on and off dozens of times a day.

ShiftChange fixes this. It lives in your menu bar, monitors which app is in focus, and instantly disables Night Shift when you switch to an app on your exclude list. When you switch away, Night Shift comes right back. No manual toggling, no forgetting, no more editing photos under an orange tint.

1. Add color-critical apps to your Exclude List
2. ShiftChange runs silently in the menu bar
3. When an excluded app gains focus, Night Shift is disabled automatically
4. When you switch to any other app, Night Shift is restored to its normal schedule

That's it. Set it and forget it.

Menu bar — see Night Shift status and active app at a glance

Build your exclude list — search and add apps with one click

Search by app name or bundle ID to quickly find what you need

Add custom application folders — useful for apps on external drives

• Per-app Night Shift control — disable Night Shift only when specific apps are in focus
• Global Night Shift toggle — turn Night Shift on or off system-wide right from the menu bar, exactly like the System Settings toggle ("Turn Off Until Tomorrow" / "Turn On Until Sunset"). Per-app switching keeps working either way
• Schedule-aware — if your Night Shift schedule kicks in while a color-critical app is in focus, the display stays unshifted until you switch away
• Theme-safe — toggling Night Shift never flips your Light/Dark appearance (some macOS versions couple the two when Appearance is set to Auto; ShiftChange guards against it)
• Menu bar app — runs quietly out of the way with a status icon
• Instant switching — Night Shift toggles the moment you switch apps, no delay
• Smart restore — respects your existing Night Shift schedule; restores it when you leave an excluded app
• Search & browse — find apps by name or bundle ID, or manually browse for .app bundles
• Custom folders — scan additional directories for apps (external drives, non-standard installs)
• Launch at Login — start automatically so you never have to think about it
• Lightweight — native Swift, no Electron, no background web processes
• Privacy-respecting — no network calls, no analytics, no data collection
• Signed & notarized — releases are Developer ID signed and notarized by Apple, so no Gatekeeper warnings

To build a distributable .dmg:

./scripts/create-dmg.sh

The version is read automatically from ShiftChange/Sources/ShiftChange/Resources/VERSION.

• macOS 13 (Ventura) or later
• Night Shift-capable Mac (most Macs from 2012 onward)

Anyone who uses Night Shift and works with color-sensitive applications:

• Photographers — Lightroom, Photoshop, Capture One
• Video editors — Premiere Pro, DaVinci Resolve, Final Cut Pro
• Designers — Illustrator, Figma, Sketch, Affinity Designer
• 3D artists — Blender, Cinema 4D, After Effects
• Developers — when previewing designs or working on UI

ShiftChange uses Apple's private CoreBrightness framework (CBBlueLightClient) to control Night Shift programmatically. It monitors NSWorkspace.didActivateApplicationNotification to detect app focus changes, and subscribes to Night Shift status notifications so schedule triggers and System Settings changes are handled even while a color-critical app is in focus.

On macOS versions where the "Auto" appearance setting is coupled to Night Shift (e.g. Sonoma), ShiftChange also guards your Light/Dark theme so its Night Shift toggles never flip it.

The app runs as a menu bar accessory (LSUIElement) with no Dock icon during normal operation. The settings window activates the Dock icon temporarily for a natural macOS experience.

See the Releases page for the full changelog.
