Flux
Flux (f.lux) is a screen color temperature adjustment utility for macOS that automatically shifts your display's color temperature based on the time of day, reducing blue light in the evening and warming the screen to help reduce eye strain and improve sleep quality. It runs in the menu bar, learns your location to determine sunset and sunrise times, and allows fine-grained customization of color temperature curves and disable schedules. The app is free and has been actively maintained for over a decade, with a large user base among students, office workers, and anyone concerned with reducing computer-induced eye fatigue.

1 suggestionFlux ships a native Apple Silicon build — the vendor released version 41 with full Apple Silicon support in late 2022, and recent releases continue to ship as Universal Binaries. If you are still running an older Intel-only version under Rosetta, update to the latest version from justgetflux.com (the official download page automatically serves the native build to M-series Macs) or download directly from the GitHub releases page. After updating, you will see noticeably better energy efficiency and no performance overhead — Flux will simply fade into the background as designed. The update is free and your existing preferences carry over.
