In early 2026, Apple computer owners were faced with an unpleasant situation: branded peripherals from Logitech suddenly lost their functionality. Users of premium mice and keyboards, which often cost more than $ 100, found that their devices had turned into ordinary accessories without additional features.
Why a critical error occurred
The incident was caused by a human factor within Logitech. The developers did not renew their Apple Developer Certificate in time, which expired on January 6. Since macOS strictly controls the legitimacy of software, the security system instantly blocked the Logi Options+ and G HUB applications.
- Stopping custom gestures and programmable buttons.
- Unable to launch the setup application (white or purple loading window).
- Cyclic errors in system logs causing CPU load.
Which devices were at risk?
The issue has affected a wide range of products that use modern AI-focused software, with the largest number of complaints coming from owners of the MX series, which is the standard for professional graphics and code work.
- MX Master 3S and MX Master 4 series mice.
- MX Keys series keyboards and MX Mechanical mechanical versions.
- Gaming devices powered by G HUB, including the Pro and Lightspeed series.
How to restore your devices to working order
It is important to understand that automatic updates within the programs will not work, as the update modules themselves are also blocked due to an invalid certificate. The only way to recover is to completely reinstall the software manually.
- Completely uninstall the current version of Logi Options+ or G HUB via Finder or dedicated cleanup utilities.
- Go to the official Logitech download site and download the latest version of the installer released after January 7th.
- If you cannot download the software immediately, a temporary solution is to change the system date to January 5, but this may cause problems with browsers and email.
Future of support and conclusions
The company’s representatives have already called this incident an “unacceptable mistake” and promised to review internal protocols for controlling certificate expiration dates. This situation once again reminds us of how dependent modern devices are on cloud technologies and software. Even the most expensive mouse for $ 150 can lose 90% of its functions due to one missed digital signature renewal deadline. Apple users are advised to always keep simple wired analogues for critical situations.
