Step\-by\-step setup lives in the docs\. ### macOS $brew install \-\-cask openlogi [Download \.dmg](https://openlogi.org/download/macos)Homebrew is recommended — or grab the signed \.dmg for Apple silicon or Intel\. ### Linux [Download \.deb](https://openlogi.org/download/linux)Packages for amd64 and arm64, with \.rpm and Arch \.pkg\.tar\.zst builds also available\. [Download \.msi](https://openlogi.org/download/windows)Signed x86\_64 and arm64 installers, validated on Windows 11 — the newest port\. Quit Logi Options\+ before launching — the two fight over HID\+\+ access, and only one app can own a receiver at a time\. On Linux, the same applies to Solaar\. Is OpenLogi made by Logitech?No\. It's an independent, open\-source project, not affiliated with or endorsed by Logitech\. "Logitech", "MX Master" and "Options\+" are their trademarks\. Do I have to quit Logi Options\+?Yes\. OpenLogi and Options\+ both speak HID\+\+ to the same device, and only one can own a receiver at a time — quit Options\+ \(including its menu\-bar agent\) first\. Which mice are supported?MX Master 4, 3S and 3, MX Anywhere 3, Signature M650 and Ergo M575 — over a Logi Bolt, Unifying or Lightspeed receiver, direct Bluetooth, or USB\. Keyboards get F\-row remapping, Fn\-lock and RGB or backlight control; Litra lights and Logitech webcams are supported too\. Does it run on Linux or Windows?All three are supported\. Linux ships \.deb, \.rpm and Arch packages with udev rules and a systemd user unit\. Windows is the newest port — validated end\-to\-end on Windows 11 hardware, with signed \.msi installers in every release\. Does it need an account or send telemetry?Neither\. The only network calls are device\-image downloads and an opt\-in update check that's off by default — everything else stays on your machine\. Where are my settings stored?In a single plain\-text TOML file\. The GUI writes your bindings, presets and profiles to it directly, the Settings window covers app\-wide preferences, and the file stays hand\-editable\.
