Logitech has released a patch for its Options+ and G Hub applications on macOS, after a certificate expiration caused problems for users of the company's mice and other peripherals.
Owners of Logitech peripherals like the MX Master series rely on the company's software to customize the configuration of their devices. However, an avoidable certificate issue led to its software becoming unusable on macOS.
A support page explains that an expired certificate was to blame for Logitech's Options+ and G Hub apps suddenly being rendered inoperable on user's Macs. The result was a flood of complaints on social media that various functions on mice and other items that relied on the apps stopped working properly.
The certificate expiry only affected Mac users, due to the way Apple has set up macOS security. If there isn't a valid Developer ID certificate, macOS can prevent the apps from running.
A simple software fix
The expired certificate means it's not a problem that can be automatically fixed. Any built-in updating system in an app won't work if the app itself cannot be run in the first place.
Instead, the fix is one that requires action by users. Download links for updated installers are available from the Logitech support page, which users are encouraged to run.
For Options+, the installer will automatically close and the app will launch as usual. For G Hub, the installer will state the software "already exists," at which point users can exit the installer and launch G Hub as usual.
In both instances, the user's devices, settings, and customizations should be fully restored.
