At the Logitech firm, they neglected to renew their Apple developer certificate, resulting in the Options+ application ceasing to function on macOS computers, and customized settings for MX Master mice and keyboards becoming inoperative. The utility for these devices simply displayed an endless loading screen and was unresponsive, while some MacBooks simultaneously overheated due to the stalled Options+ procedure, draining the battery in the background.
IT System Malfunction
Logitech failed to extend a developer certificate — and millions of mice on Mac turned into bricks, reports The Verge. The local application for customizing device buttons stopped working due to external factors.
On January 6, 2026, at 22:39 Moscow time, Logitech’s developer certificate for Apple expired. Suddenly, across the globe, the Options+ application stopped working for Mac users — and along with it, all custom configurations for MX Master mice and keyboards vanished.
The primary symptoms experienced by most Mac users involved a continuous and unsuccessful loading of the Logitech application; in some instances, the frozen Options+ remained active in the background, causing laptop overheating and accelerated battery discharge.
Older Logitech mouse models (Logitech M280, Logitech G102, Logitech M100) continue to operate normally, but newer Logitech MX Master 3S and Logitech MX Master 4 mandatorily require Options+, and with its failure, the G HUB gaming utility also became defunct.
Logitech programmers forgot to renew the Apple developer certificate, which resulted in operational failures for millions of mice and keyboards on Macs worldwide.
The Logitech company officially confirmed the issue and stated that a fix is being prepared, expected to be released soon. However, at the time of writing, the disruption persists.
Logitech is a Swiss brand renowned for its computer peripheral hardware. Established in 1981, it has become a leader in producing mice, keyboards, webcams, and audio devices. With a focus on innovation, ergonomics, and environmental consciousness, the brand offers products for work, gaming, and creative pursuits.
Attempts to Rectify Everything
As of January 8, 2026, there is no reliable self-service method to completely resolve the emergent problem. Temporary restoration of the application’s functionality is achievable through two methods, though both carry significant constraints.
Firstly, altering the macOS system date back a few days allows the application to launch correctly but simultaneously disrupts SSL connections and entirely blocks access to iCloud cloud services.
Secondly, installing one of the prior (outdated) versions of the application via the Homebrew package manager temporarily restores functionality, but this is not advised for extended use due to the absence of security updates.
Excessive Application Features
The core cause of the instability, according to McRunner experts’ assessment, lies in the overgrown functionality of the Logi Options+ application, which: demands a consistently active internet link for periodic license validation and settings synchronization with the manufacturer’s servers; implements an extensive set of capabilities, including ChatGPT integration, support for plugins from the built-in marketplace, and intricate customization scenarios.
Meanwhile, without the installed and operational Options+ application, a substantial portion of the features on modern premium Logitech peripherals (specifically, customization of auxiliary buttons, gesture commands, advanced scroll wheel settings, and per-application profiles) becomes inaccessible.
“In 2012, mouse configuration was a straightforward system utility: click a button, select an action, close. In 2026, Options+ is a media hub with action buttons, various macros, ChatGPT integration, and plugins from marketplaces,” one user complained.
Consequently, for users reliant on the advanced capabilities of Logitech devices on macOS, the situation remains a forced compromise until an official update is released. It is advisable to monitor Logitech’s official support channels and updates in the Mac App Store or on the manufacturer’s website.
