One glyph, three live states

DuoBar adapts the iPhone Duo-style three-in-one status concept for the Mac menu bar. One compact glyph presents the system information normally spread across several indicators:

• Outer arc → a live Battery Ring on MacBooks, or an Adaptive Ring on desktop Macs
• Center → the active network: Wi-Fi, Ethernet, or an offline/fallback state
• Four lower dots → live output volume

Persistent status stays monochrome and native-looking. When AirPods or another supported Bluetooth audio output becomes active, the center briefly transitions from Network → AirPods/headphones → twork. Disconnecting does not trigger an animation. p>

Adaptive Ring and Battery Ring

On MacBooks, the outer Battery Ring shows live battery level, a dynamic charging bolt, and optional battery color coding for charging, Low Power Mode, and low-battery states. On desktop Macs, Adaptive Ring remains Neutral when there is no meaningful performance activity and automatically surfaces sustained CPU, memory, or thermal pressure when appropriate. It remains automatic: there is no manual metric selector.

DuoBar on macOS

The current 1.3.1 release brings the Battery, Network, and Volume foundation together with MacBook Adaptive Ring behavior, refined controls, adjustable icon size, and installation polish.
