Bluesnooze is a menu bar utility that automatically toggles Bluetooth off when a Mac goes to sleep and back on when it wakes. It addresses the scenario where sleeping Macs unexpectedly connect to paired Bluetooth devices such as headphones, speakers, or keyboards. (Free, open-source)
The app monitors macOS sleep and wake events and reacts by toggling the system Bluetooth power state. No manual interaction is required after setup — once configured to launch at login, it operates entirely in the background. The menu bar icon confirms the app is running, and a “Launch at Login” toggle is accessible from the status bar menu.
Installation is available via direct download (the app is Apple-notarized) or through Homebrew with brew install bluesnooze. The project is open source under the MIT license with source code on GitHub.
System requirements: macOS Monterey (12.0) or higher. The app is written in Swift and uses private macOS APIs to control Bluetooth power state. Resource usage is minimal, as actions only occur on sleep and wake events rather than continuous monitoring.
Limitations: Bluesnooze is incompatible with the “Allow your Apple Watch to unlock your Mac” feature due to its use of private APIs — both cannot be active simultaneously. The app does not support selective disconnection; it toggles all Bluetooth rather than managing individual paired devices. No Mac App Store version is available.
Alternatives: Sharptooth (paid, adds per-device hotkeys and battery monitoring), One Switch (broader system toggle panel that includes a Bluetooth switch).
Suitable for users who move between locations with shared Bluetooth devices, or who want to prevent a sleeping Mac from connecting to nearby paired speakers or headphones.
