Logitech Bug Locks Out Mac Users: Expired Certificate Blamed

Many Logitech accessory users on Mac encountered problems with their devices recently, as critical software failed to operate correctly. The issues, which affected customized buttons and scrolling functions, were caused by an expired digital certificate required by Apple for app security.

Logitech's certification, essential for its applications like Options+ and G Hub, expired on January 6th. This expiration prevented the software from starting, thereby disabling many Logitech peripherals on Mac devices. The company has acknowledged the oversight, with a spokesperson calling it an "inexcusable mistake."

A fix is now available, but users must manually install it for the last four macOS versions, as the certificate issue also impacted the installer itself. Logitech advises all users, even those unaffected, to apply the update to ensure future accessory functionality.
