/ engine.md

A menu bar app on top of the raw USB HID protocol — every command verified against real hardware.

Direct USB HID

Talks to the mouse with the same 90-byte report protocol documented by the OpenRazer project — DPI, lighting, buttons and battery, no vendor software in between.

Sandboxed & quiet

Fully App-Sandboxed with a single USB entitlement. No kernel extensions, no helpers, no background services, no network access — and zero telemetry.

Settings that persist

DPI stages and lighting are restored to the mouse on every reconnect, and button mappings live in the mouse's own onboard memory — they survive without the app running.

/ install.sh

Coming to the Mac App Store — sandboxed, notarized by Apple, one-click install.
