Only Switch
OnlySwitch is a macOS menu bar utility that groups common system toggles and quick actions into one lightweight control panel.
What is Only Switch?
OnlySwitch is a macOS menu bar utility published by Bo Liu that brings many commonly used system switches and convenience tools into a single menu bar app. Its official site describes it as an open source app designed for macOS, and its public project presence is tied to the jacklandrin/OnlySwitch repository, which is consistent with the bundle ID jacklandrin.OnlySwitch. Typical uses include quickly toggling Dark Mode, hiding desktop icons or hidden files, keeping a Mac awake, and accessing other small desktop controls without opening System Settings. The product site also lists extras such as a radio player, desktop widgets, an Xcode data cleaner, and natural-language AI system control. Users will usually encounter it as a utility they intentionally install for workflow convenience, especially if they like menu bar tools or need frequent access to macOS display and desktop options. Because it changes visible system behavior and may request permissions for some actions, it is best understood as a legitimate utility app rather than a background system component.

Safety overview
Status: Mostly safe
OnlySwitch appears to be a legitimate macOS utility with an official product site and a public open source project presence. It is not known as malware, but it can change system behavior and may need accessibility or other macOS permissions for some features, so review granted permissions if you no longer use it or do not recognize the installation.
Recommendation: Keep it if you actively use its menu bar toggles or convenience tools. If you do not use it, removing the app is usually reasonable after checking whether you rely on its widgets, login item, or granted permissions.
