BEFORE INSTALLING

About this preview

This release is ad-hoc signed, not Developer ID signed or notarized. macOS may block opening it. Review the source, release provenance and security warning before deciding whether to proceed.

Music requires your opt-in and macOS permission for system audio. Login launch, closed-lid operation and the administrator brightness override are optional. Closed-lid and administrator behavior still need physical validation.

Normal Quit restores the previous logo curve. If recovery is needed, use Restore Light.
