If you’re a Mac user with Logitech accessories and you’ve noticed that your settings and customizations seem to have gone away this week, you’re not alone.
The company’s Logi Options+ and G Hub apps for macOS abruptly stopped functioning on Monday, refusing to launch and reverting all accessories’ settings to their built-in defaults.
The culprit, according to both a Logitech support page and Reddit posts from Logitech Head of Global Marketing Joe Santucci, was a security certificate that was inadvertently allowed to expire, rendering both apps non-functional.
“The certificate that expired is used to secure inter-process communications and the expiration results in the software not being able to start successfully,” wrote Santucci in one post. “We dropped the ball here,” he said in another post. “This is an inexcusable mistake. We’re extremely sorry for the inconvenience caused.”
Logitech is already offering patches for both apps that include an updated certificate. But unfortunately for users, one of the features broken by the expired certificate is the app’s built-in updater, meaning that there’s no automated way for Logitech to fix this problem. Anyone who wants their apps to work and their customizations to return will need to manually grab the patch (or updated versions of the apps, which Logitech says it is also working on). If you use both apps, each will need to be patched separately.
