[Bug]: MX Master 3 keeps disconnecting

[timharek]

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).

Which part of OpenLogi?

GUI (desktop app)

OpenLogi version

0.6.16

Operating system

macOS

OS version & architecture

macOS 26.5.1

Device model

MX Master 3

How is the device connected?

Other / not sure

Affected area(s)

• Device discovery / detection
• Button remapping
• DPI control
• SmartShift
• Per-application profiles
• Battery status
• Settings / configuration (TOML)
• Auto-update
• Menu bar / tray
• Other

What happened?

My mouse keeps disconnecting, so when my machine eventually goes to sleep my scrolling doesn't work as expected anymore.

Also, the openlogi CLI wasn't installed with Homebrew when I installed the cask. I thought it was supposed to install alongside eachother.

I have tried going back multiple versions, but to no avail. I have tried both installing using Homebrew and directly from GitHub releases.

My device is using the Unify receiver.

My first initial connection was excellent, but when I came back to my machine, it didn't connect. And when I "force" it to connect by readding it, it disconnects after a few seconds.

Steps to reproduce

1. Leave machine unattended (wait for sleep)
2. Try to use mouse with config
3. Doesn't work…
4. "Force" reconnecting by readding
5. Disconnects after a few seconds.
