Mainspring

Mainspring reveals the settings macOS hides and turns them into 90+ one-click power-ups for Finder, the Dock, screenshots, animations, windows and more. Each power-up is a real macOS setting that Mainspring writes for you, labelled in plain English and snapshotted before it changes, so any switch flips back in one click. No Terminal, no commands copied off a forum, and nothing permanent.

Key Features

Recipes: curated bundles of power-ups that work together, applied and reverted as a set. Speed Boost, Screenshot Studio, Privacy and Security, Declutter and Focus, Writer's Focus, Power Windows, Finder Power and Developer Setup (hidden files, all file extensions, fast key repeat).

90+ power-ups: show hidden files, full path in the Finder title, folders on top, no .DS_Store files on network drives, an instant Dock, no window animations, faster Mission Control, reduced transparency, silenced UI sounds, a password on sleep, no personalized ads, a custom screenshot folder, Dock size and magnification, Hot Corners and more.

Power controls: keep the Mac awake with the lid closed, or caffeinate it on a timer.

Scenes: build a scene from any mix of power-ups and flip your whole Mac between contexts such as Work, Focus and Presentation in a click.

Automation: scenes can apply themselves when your context changes, such as power, displays, time of day or an app opening.

Fully reversible: every power-up is a standard macOS setting, snapshotted before it changes. Recipes revert as a group.

Privacy

Mainspring runs locally with no account and never uploads anything. The only network calls are to verify your license.
