TL;DR
Logitech acknowledged that an unrenewed certificate caused Logitech mice connected to macOS to lose configurable features. Users reporting issues on Reddit saw buttons and scrollwheel customization stop working in Logi Options Plus; Logitech has released a fix.
What happened
Mac users running Logitech's configuration software encountered failures that disabled programmable inputs on some mice after a required certificate lapsed. Multiple Reddit posts flagged the problem, noting that customization controls in Logi Options Plus stopped responding; users specifically reported that buttons and the scrollwheel on devices such as the MX Master 4 no longer behaved as configured. The issue stemmed from a certificate that was not renewed, which interfered with the software’s operation on macOS. Logitech has since deployed a remedy intended to restore the affected features. The source material does not provide details about the exact certificate type, how long the problem persisted, or whether any other platforms were affected.
