MITEligibility checkedmacOSvrelease_2.7.2 · 5.9k ★ · pushed Aug 11, 2026

All-in-one macOS menu-bar switches

Metadata checked Aug 18, 2026

Why this pick

Best overall replacement: it mirrors One Switch’s multi-toggle concept most closely, has a current July 2026 release, and offers direct Homebrew/DMG installation under an MIT license.

A close functional match that gathers many system actions into a customizable status-bar panel, with keyboard shortcuts, widgets, imported Shortcuts, and user-defined script switches.

Key capabilities
  • 01Native switches for dark mode, desktop icons, hidden files, Night Shift, screen saver, AirPods/Bluetooth, keep-awake, Dock/menu-bar visibility, mute, and display dimming.
  • 02Customizable switch order and availability, plus Apple Shortcuts import and Shell/AppleScript extensions.
  • 03Apple Widgets and keyboard control for quick access outside the main panel.
Caveats
  • Some switches are marked partly finished or require administrator access.
  • Several features are OS-specific; Evolution requires macOS 13 or later and Only Agent requires macOS 26 or later.
  • Versions 2.5.6 and earlier require manual updating or Homebrew according to the README.

GPL-3.0-onlyEligibility checkedmacOSv3.3.1 · 5.5k ★ · pushed Aug 18, 2026

Modular all-in-one macOS menu-bar toolkit

Metadata checked Aug 18, 2026

Why this pick

Strongest power-user alternative: it covers the same quick-action surface while adding a modular toolkit and a rapid August 2026 release cadence; it is the best fit when broader tooling is welcome.

Full review — capabilities, 3 caveats, evidence

A broad local-first toolbox with One Switch-like quick controls plus keep-awake, display, audio, monitoring, window, capture, cleanup, and automation features; unused modules can be removed.

Key capabilities
  • 01Quick toggles for dark mode, microphone mute, hidden files, desktop icons, screen lock, display off, screen saver, Trash, and disk eject.
  • 02Keep-awake timers, lid-closed mode, display controls, and volume/output routing.
  • 03Install only selected modules; no account, telemetry, or subscription, with GPL-licensed source.
Caveats
  • Requires macOS 14 or later on Apple Silicon.
  • Optional permissions are needed for advanced modules such as window previews, audio routing, capture, and deeper cleanup.
  • The source is GPL-3.0-or-later, and the project keeps its name, logo, and visual identity under separate trademark terms.

KeepingYouAwake

MITEligibility checkedmacOSv1.6.8 · 6.8k ★ · pushed Aug 15, 2026

Keep your Mac awake from the menu bar

Metadata checked Aug 18, 2026

Why this pick

Best focused substitute for One Switch’s keep-awake function: a long-running MIT project with 2026 maintenance commits, a substantial release history, and very low setup overhead.

Full review — capabilities, 3 caveats, evidence

A focused native menu-bar utility for one-click or timed sleep prevention, built around Apple’s caffeinate utility and maintained with current macOS compatibility work.

Key capabilities
  • 01One-click indefinite or timed keep-awake sessions.
  • 02Optional low-battery cutoff and support for Retina displays and Dark Mode.
  • 03Homebrew cask or direct GitHub release installation for macOS 10.13 and newer.
Caveats
  • It intentionally covers sleep prevention rather than One Switch’s dark-mode, AirPods, desktop, display, or notification controls.
  • Closed-lid sleep prevention is limited by macOS; the project documents that portable Macs need the lid open.
  • The latest stable release is 1.6.8, so future work may remain compatibility-focused rather than expanding the feature set.
