Pre-flight checklist

• I searched existing issues and this is not a duplicate.
• I am on the latest release or a recent master build.
• I quit Logi Options+ before running OpenLogi (the two apps fight over HID++ access and only one can own a receiver at a time).

Operating system

macOS

OS version & architecture

macOS Tahoe 26.5, Apple Silicon

How is the device connected?

Bluetooth (direct, no receiver)

Affected area(s)

• Other
