Alin Panaitiu released version 5.4.2 of Lunar, his utility for controlling external display brightness from a MacBook (see “Total Eclipse of the Mac: Lunar Controls Third-Party Displays,” 5 August 2021). The update introduced a new internal system API that’s used to react to built-in display brightness changes instead of polling continuously for them, helping to reduce CPU usage. It also fixes a bug that prevented software dimming from returning to 100% after restarting the app and ensures the BlackOut dialog appears correctly. Shortly after this release, Lunar was updated to version 5.4.3 to resolve an issue with screen waking and reconnecting. Lunar is free to use but costs $23 to unlock advanced features such as unlimited adjustments and app presets. ($23 new, free update, 16.6 MB, release notes, macOS 10.15+)
