Logitech Blames 'Inexcusable Mistake' After Certificate Expiry Breaks macOS Apps

Logitech users on macOS found themselves locked out of their mouse customizations yesterday after the company let a security certificate expire, breaking both its Logi Options+ and G HUB configuration apps.

Logitech MX Master 3S
Logitech devices like its MX Master series mice and MX Keys keyboards stopped working properly as a result of the oversight, with users unable to access their custom scrolling setup, button mappings, and gestures. It wasn't long before the Logitech subreddit was awash with frustrated reports as people discovered their configured peripherals had suddenly reverted to default settings.

The Developer ID certificate is the digital signature macOS uses to verify legitimate software. The certificate that Logitech allowed to lapse was being used to secure inter-process communications, which resulted in the software not being able to start successfully, in some cases leading to an endless boot loop.

Logitech has since released a patch for macOS 26 Tahoe, macOS 15 Sequoia, macOS 14 Sonoma, and macOS 13 Ventura that resolves the issue. However, users need to download and install it themselves, since the certificate expiry also prevented the apps' built-in updaters from working. From Logitech's support page acknowledging the issue:

The problem was caused by an expired certificate required for the apps to run. Because the certificate also affected the in‑app updater, you will need to manually download and install the updated version of the app. Please do not uninstall the app.

Older macOS versions will get a fix "at a later time," the support page adds. On a positive note, it seems user settings survived the blunder, with Logitech promising that profiles and customizations remain intact after manual patching is completed.

"We dropped the ball here. This is an inexcusable mistake," Logitech spokesperson ATXsantucci admitted on Reddit. "We're extremely sorry for the inconvenience caused."

(Thanks, Brad!)

Oh I know how this kind of thing happens...someone who is responsible for this has it on their calendar, they leave the company, new replacement doesn't know anything about it, and it lapses.

I may have seen this play out many times throughout my IT/Software dev career....

This is exactly it. I've stopped allowing people to put this in their personal calendars, its shared team/department calendar only.

I do software consulting, mostly around project rescues for failed/failing projects. This happens all the time. We actually track certificate expirations even after we’re done with our work, and will notify clients years later so that they can be sure to update them before they expire. But, nearly as often as not, they don’t and then we get a frantic call because the thing we built for them suddenly stopped working one day.
