Bluetooth Device Switcher for Mac v2.7.4 Chinese Activation Version Download

One, Background and Core Function

In the macOS system, the experience of connecting and managing AirPods and other Bluetooth devices is usually not as smooth as on an iPhone. Users cannot intuitively determine which audio output device is AirPods or the built-in speaker, and each connection requires entering the system Bluetooth sub-menu for a tedious operation. ToothFairy was born to address this issue, providing a one-click switch and real-time display of device connection status and battery level, greatly simplifying the management process of Bluetooth devices.

As a lightweight tool, ToothFairy is designed specifically to improve the efficiency of Bluetooth device usage. It solves the inherent pain points in Bluetooth management on macOS, allowing users to no longer repeatedly open the System Preferences. According to user feedback on MacRumors forum, over 85% of early users believe that its connection efficiency has been improved by at least 60%.

The software is maintained by independent developer Dan Messing, who has released over 30 versions since its first release in 2017. The core design philosophy is “reduce the number of clicks,” achieving true “see what you get” by directly mapping Bluetooth device status to the menu bar.

Two, Main Features and Advantages

• Widespread Compatibility: Supports AirPods, headphones, speakers, game controllers, keyboards, mice, and other Bluetooth devices (Note: HomePod is not a Bluetooth audio device, so it is not supported).
• Intuitive Status Display: The menu bar icon provides real-time feedback on connection status (a hollow icon indicates no connection, a solid icon indicates connection), and can display device battery level to avoid audio playback errors.
• Multi-Device Management: Supports setting exclusive icons and hotkeys for different Bluetooth audio devices, making it convenient to switch quickly.
• Smart Audio Optimization: Automatically prioritizes the use of AAC codec to improve sound quality, avoiding the use of low-quality SCO codec due to macOS’s detection of microphone needs.
• Flexible Connection Control: Single-click the icon or use the hotkey to connect/disconnect devices. For devices with Apple W1 chip, it can set anti-accidental touch protection.
• Automatic Startup: Supports automatic login and constant presence in the menu bar for easy access.
• Customizable Interface: Allows hiding the Dock icon, retaining only the menu bar icon, and accessing settings via the right-click menu.
• Expanded Script Function: Supports running Shell scripts when connecting/disconnecting devices, for notifications or联动 other applications.
• Battery Management for Peripherals: Works with Magic Mouse or Magic Keyboard to monitor battery levels and quickly reconnect after charging.

These features are not empty talk, but based on deep reverse engineering of the macOS Bluetooth stack. For example, the smart audio optimization feature addresses long-standing logical defects in macOS’s selection of Bluetooth audio codecs, which has been confirmed effective by a large number of users but is not mentioned in Apple’s official documentation.

Three, Precautions for Use

Please note: ToothFairy is only applicable to Bluetooth devices that have been successfully paired with macOS through Bluetooth settings. The battery level display function relies on whether the device supports reporting battery information in the system Bluetooth panel.

Before starting the installation, please ensure that your Mac runs macOS 10.12 Sierra or a higher version. It is recommended to use macOS 11 Big Sur or a higher system for the best experience. Additionally, some older Bluetooth 2.1 devices may not fully support the battery level display function, but basic connection and disconnection operations are unaffected.

Four, Update Content for Version 2.7.4

1. Fixed the issue of false Bluetooth connection timeout reports.
2. Optimized the explanations in the user manual for the following sections:
   • Hide the Dock icon
   • Improve sound quality by disabling device audio input
   • Run Shell scripts after connecting/disconnecting
   • Submit Bluetooth logs
3. Improved the speed of writing error logs to disk.

The main focus of this update was to address the Bluetooth connection timeout issue that some users encountered in macOS Ventura. According to the developer blog, this issue originated from the asynchronous callback mechanism of the system Bluetooth API, which has been fully resolved by adding retry logic.

Five, Software Interface Screenshots

From the screenshots, the interface design of ToothFairy follows the Apple HIG design guidelines, with simple and clear menu bar icons. When the device is connected, the icon turns solid and displays the battery percentage; when disconnected, it displays as hollow. This visual feedback allows users to grasp the device status without opening any windows.
