What is Tethered (Tumerit)?

Tethered is a macOS menu bar app for managing battery charging, power behavior, and automation in one place. Set a charge limit, use Sailing and Top-up, monitor battery health and temperature, and configure power modes, Caffeinate, sleep and wake behavior, and display brightness.

Create schedules and per-app rules so these settings respond to your power source, battery level, and workflow. Saved task profiles can temporarily adjust power and resource behavior during demanding work, including local AI tasks. Tethered also supports keyboard shortcuts, Apple Shortcuts, Siri, Alfred, Raycast, and a local MCP Bridge. Basic settings are free; Pro Access unlocks expanded controls for a one-time $9.99 per-device purchase.
