NativeLogi is an independent, open-source macOS utility for Logitech mice. It is built for people who want native device control without running the heavy Logi Options+ background stack.
Logi Options+ can intercept Logitech mouse buttons and turn physical side buttons into app-level back/forward actions. That is fine in browsers, but it breaks games and tools that expect real Mouse4 / Mouse5 input.
NativeLogi starts by restoring native side-button behavior for MX Master-style mice, then grows into a lightweight local control panel for DPI, SmartShift, button bindings, and per-app profiles.
- Native Mouse4 / Mouse5 pass-through for Logitech side buttons on macOS.
- DPI controls over HID++.
- SmartShift / wheel controls where supported by the device.
- Local configuration, no account requirement, no telemetry.
- Works with Bluetooth-direct devices and supported Logi Bolt paths.
NativeLogi is an early fork based on OpenLogi. The first public goal is a stable macOS build for Logitech MX Master users who want native side buttons and basic device controls without Logi Options+.
The codebase still uses OpenLogi crate names internally. The public product name, app packaging, icon, and documentation are being migrated gradually so the working HID++ implementation stays stable.
There is no signed public release yet.
For now, build from source:
cargo build -p openlogi-agent -p openlogi-gui --release
The current development binaries are:
target/release/openlogi-gui
target/release/openlogi-agent
The internal crate and binary names still use openlogi while the public app
brand is being migrated to NativeLogi.
NativeLogi needs two macOS permissions:
- Accessibility: required for the mouse event tap and button remapping.
- Input Monitoring: required to open HID devices, especially Bluetooth-direct Logitech mice.
If the app is rebuilt or re-signed locally, macOS may treat it as a new app and require the permissions to be granted again.
- Package a NativeLogi-branded
.app. - Replace the remaining OpenLogi app names and bundle identifiers.
- Add a reproducible release workflow.
- Add a first public DMG / ZIP release.
- Improve game-profile ergonomics for native side-button use.
