One Switch
One Switch is a macOS menu bar utility that puts common system and convenience toggles in one place for quick access.
What is One Switch?
One Switch is a native macOS utility from Fireball that collects everyday system and convenience controls in a single menu bar app. It is designed for users who want faster access to common Mac actions without digging through System Settings or Terminal commands. Typical uses include hiding desktop icons, switching Dark Mode, keeping the Mac awake, launching the screen saver manually, and quickly connecting supported audio devices such as AirPods. The app focuses on lightweight, click-to-toggle actions that fit neatly into normal desktop workflows. It is intended for personal productivity and day-to-day Mac customization rather than deep system administration.
Key features
- Toggle Dark Mode from the menu bar
- Hide or show desktop icons with one click
- Keep your Mac awake to prevent sleep or screen saver activation

Safety overview
Status: Mostly safe
One Switch is a legitimate Mac utility for changing everyday system behaviors, so some features may request normal macOS permissions or adjust settings related to appearance, sleep, desktop visibility, or connected devices. Those actions are expected for its purpose, but you should still grant only the permissions you want to use. If you remove it, its menu bar shortcuts and convenience toggles will stop working, while the underlying Mac features remain available through macOS itself.
Recommendation: Keep One Switch if you use its menu bar shortcuts to control common Mac settings more quickly. If you no longer use those toggles, you can remove it without harming macOS and return to managing the same settings through standard system controls.
