4 POWER-UPS
Applied
Instant Dock
No window animations
Faster Mission Control
Reduce transparency
Mainspring reveals the settings macOS hides — as one-click, fully reversible power-ups. Wind it up exactly how you like it; unwind any change just as fast.
Curated bundles of power-ups that work together. Apply as a set, revert as a set — nothing is permanent.
Snappier Dock, instant animations, faster everything.
No shadow, no floating thumbnail, smaller files.
Lock on sleep, kill ad tracking, Siri and lookups.
Hidden desktop, auto-hide Dock, a quieter screen.
No autocorrect, smart quotes, or UI sounds.
Drag from anywhere, double-click zoom, full keys.
Path bar, status bar, list view, smarter search.
Hidden files, all extensions, fast key repeat.
Each power-up is a real macOS setting Mainspring writes for you — labelled in plain English, and snapshotted so it flips back in a single click.
The tweaks power users dig out of Terminal — named in plain English, and one click to flip back.
No commands copied off a forum, nothing permanent. Mainspring writes the setting and remembers how to undo it.
Build a scene from any mix of power-ups, then flip between contexts instantly. Nothing touches your Mac until you switch to it.
Mainspring watches in the background and switches when your context changes — power, displays, time of day, an app opening.

Yes. Every power-up is a standard macOS setting, snapshotted before it changes, so each one flips back in a single click. Recipes revert as a group, and nothing is permanent — that's the whole point.
No. Mainspring changes settings locally and never uploads anything. The only network calls are to verify your license.
One full day, every feature, no account or card. After that you unlock everything forever with a one-time $29 license.
Some power-ups (like keeping your Mac awake with the lid closed) need access the App Store sandbox forbids. Mainspring is Apple-signed and notarized, so Gatekeeper trusts it — it installs with a normal double-click.
One license activates up to three of your Macs. You can move a seat any time.
A calmer, faster, more precise Mac — one click at a time.
