TryMainspring Reviews and Details

Questions & Answers

1. What makes TryMainspring unique?

   Mainspring takes the settings macOS hides, the ones people usually dig out of Terminal with defaults write commands, and turns them into plain-English switches. The difference is the undo: before Mainspring changes anything, it saves the exact value that was there, so every power-up and every recipe flips back in one click. Beyond single switches, you can save whole setups as Scenes and let them apply themselves when you unplug, connect a display, open an app or reach a set time. A Mac Health panel also checks for stuck system services, low disk space, memory pressure and long uptime, and offers a one-click fix.

2. Why should a person choose TryMainspring over its competitors?

   • Every change is reversible: each setting is snapshotted before it changes, and recipes revert as a group
   • Plain English instead of cryptic preference names, with curated recipes for speed, privacy, focus, Finder and developer setups
   • Scenes and automation switch your whole Mac by context, not just one setting at a time
   • Power controls like keeping your Mac awake with the lid closed, which need access App Store apps aren't allowed
   • Works locally: no account, nothing uploaded, the only network call is the license check
   • $29 once for up to 3 Macs with free updates, and a full 1-day trial first

3. How would you describe the primary audience of TryMainspring?

   Mac users who know macOS can do more than System Settings shows, but don't want to paste Terminal commands they can't undo. That includes developers who want hidden files and fast key repeat, designers and writers who want a quieter, faster interface, and anyone setting up a new Mac exactly how they like it. It is made for individuals tuning their own Macs.

4. What's the story behind TryMainspring?

   Most of the best macOS tweaks live in forum threads and blog posts as Terminal commands. You copy one, paste it, restart the Dock, and a month later you have no idea what you changed or how to put it back. We wanted the same power with none of that risk.

   Mainspring started as an engine with one rule: never change a setting without first recording how to undo it. Every power-up, recipe and scene is built on that rule. The name comes from the spring that powers a mechanical watch: you wind your Mac up exactly how you like it and can unwind any change just as fast. Mainspring is made by Everyday Mac Tools, a small studio that builds native Mac apps.

5. Which are the primary technologies used for building TryMainspring?

   Swift 6, SwiftUI and AppKit, with a native menu bar item and window. Settings are read and written through Apple's CFPreferences API, with each prior value recorded so it can be restored. Power settings such as lid-closed sleep go through a small privileged helper over XPC that only accepts a fixed list of operations, never arbitrary commands. There are no third-party dependencies. It ships as a universal app for Apple silicon and Intel, Developer ID signed and notarized by Apple, and is also available through Homebrew.
