Logitech users on macOS lost access to their mouse and keyboard customizations after the company let a security certificate expire. The mistake broke Logi Options+ and G HUB, the apps that many people use to control scrolling, buttons, and gestures.
MacRumors first spotted the issue as devices like the MX Master series mice and MX Keys keyboards stopped behaving as configured. As a result, many users saw their settings reset to defaults. Soon after, complaints spread online as people realized they could no longer manage their peripherals.
macOS uses a Developer ID certificate to verify that software is legitimate. When Logitech allowed its certificate to expire, its apps lost that verification. Because of that, macOS blocked them from running. In some cases, users reported repeated startup issues tied to the failed apps.
Fix and what users must do
Logitech has released a manual patch for macOS 26 Tahoe, macOS 15 Sequoia, macOS 14 Sonoma, and macOS 13 Ventura. Users must download and install it themselves. The built-in update tools did not work because the expired certificate also blocked the updater.
Logitech said older macOS versions will receive a fix later.
Despite the disruption, your profiles appear to be safe. Logitech said user settings and customizations remain intact after you apply the patch.
In a public statement posted on Reddit, a Logitech spokesperson acknowledged the failure, calling it “an inexcusable mistake” and adding, “We’re extremely sorry for the inconvenience caused.”
If your mouse or keyboard stopped working as expected, install the manual update. Once you do, your custom settings should return.
