Logitech macOS Bug Triggers Widespread Mouse Issues

Logitech macOS bug reports surged after Mac users noticed their mouse customizations suddenly stopped working. Many searched for answers about why scroll wheels, gesture controls, and extra buttons failed overnight. The issue was traced to Logi Options Plus, the essential software used to customize Logitech mice on macOS. Users reported the app refusing to launch or getting stuck in endless startup loops. Popular devices like the MX Master series were among the most affected. Confusion grew as the hardware itself appeared fine, pointing to a software-side failure. Logitech has now confirmed the cause and released a fix, but users must install it manually.

Logi Options Plus Failure Frustrated macOS Users

Mac users took to Reddit and forums to share nearly identical experiences with Logitech accessories. Customized scrolling directions reverted to defaults without warning. Programmable buttons stopped responding entirely during normal use. Some users said the Logi Options Plus app became unusable the moment they opened it. Others noted gesture-based controls disappeared despite no system updates. These reports quickly revealed a pattern limited strictly to macOS devices. Windows users, by contrast, experienced no disruption at all. That distinction ultimately helped identify the root of the problem.

Expired Certificate Caused the Logitech macOS Bug

Logitech confirmed the issue stemmed from an expired Developer ID certificate. macOS blocks applications that fail certificate verification as part of its security framework. Once the certificate expired, affected Logitech apps could no longer run correctly. Both Logi Options Plus and Logitech G Hub were impacted by the same underlying issue. Apple’s strict enforcement meant the apps couldn’t bypass the failure. Similar certificate-related outages have affected other developers in the past. This explains why the problem appeared suddenly and only on Mac systems.

Manual Patch Released Due to Update Failure

Logitech has now released a patch to resolve the macOS bug. Users must install it manually because the expired certificate also broke the in-app updater. Logitech says the fix restores full functionality to affected mice. Custom profiles, button mappings, and user settings should remain intact after installation. The patch currently supports macOS 26 Tahoe, macOS 15 Sequoia, macOS 14 Sonoma, and macOS 13 Ventura. Support for older macOS versions is planned for a later release. Logitech has published official instructions on its support page.

Why Windows Users Were Never Affected

The issue never reached Windows users due to differences in platform security enforcement. Windows does not rely on the same Developer ID certificate system as macOS. As a result, Logitech’s Windows software continued running without interruption. This platform divide added to early confusion among users. Many assumed a faulty update or hardware defect at first. The macOS-only nature of the problem later clarified the real cause. It also highlighted how dependent accessory software has become on operating system security rules.

Logitech Admits Mistake as Trust Takes a Hit

Logitech publicly acknowledged the error, stating it “dropped the ball.” While the fix is now available, the incident raised concerns about software reliability. For professionals relying on advanced mouse features, even short outages can disrupt workflows. The situation underscores how a single expired certificate can cripple widely used hardware tools. Logitech’s response was swift once identified, but users still had to troubleshoot manually. The company says it is reviewing processes to prevent similar issues. For now, affected macOS users can finally regain full control of their Logitech mice.
