Mainspring

Mainspring reveals the settings macOS keeps hidden and turns them into simple, labelled switches, each with an undo button. No Terminal, no defaults write commands, and nothing you cannot put back.

Flip more than 90 power-ups across the Dock, Finder, keyboard, trackpad, privacy, performance, screenshots, and the menu bar. Group them into one-click Recipes, save whole setups as Scenes you switch between, and revert any change instantly.

Highlights:

• 90+ one-click, fully reversible macOS tweaks, every one with an undo button
• Recipes: apply a whole set of settings at once (Speed Boost, Declutter and Focus, Developer Setup, and more)
• Scenes: save and switch between complete configurations
• Clean Mode: lock the keyboard and trackpad so you can wipe your Mac without typing gibberish
• Private Folders: hide folders from Spotlight and Finder
• Network panel: hotspot mode, DNS presets, low-latency mode, and a built-in speed test
• Caffeinate: keep your Mac awake for a set time, no Terminal needed
• Fast in-app search across every setting

Mainspring is a native Swift app, not Electron. It is signed and notarized by Apple. One-time purchase of 29 dollars with a free trial, no subscription and no account required.
