Mountain Tweaks
Mountain Tweaks is a macOS system utility designed to provide users with access to hidden preferences, settings and customisation options not exposed in the standard System Preferences or System Settings interface. It was intended for advanced users seeking fine-grained control over appearance, performance, networking and other system behaviour. The app has been discontinued by its developer and is no longer maintained.

1 suggestionMountain Tweaks has been discontinued by its developer and is no longer supported or updated. Whilst Roaring Apps indicates a universal binary was available at some point in the past, the app is now end-of-life and the developer has ceased active development. Since the app is abandoned, it will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028), leaving you without access to its functionality. Rather than relying on an unsupported system tweaker, consider using macOS's built-in settings and preferences, which evolve with each release. If you need specific customisations that Mountain Tweaks once provided, check whether modern third-party tools like System Preferences or OmniFocus can meet your needs, or consult the macOS release notes for official ways to adjust the settings you care about. The most reliable path forward is to identify which specific tweaks you depend on and find current, actively maintained alternatives or native system options to replace them.
