Logitech just showed how a tiny oversight can cause a huge headache on macOS.
This week, the company’s Logi Options+ and G Hub apps for Mac suddenly stopped working. They refused to launch and quietly dumped users back to the factory defaults on their mice, keyboards, and other accessories.
The culprit: an internal security certificate Logitech let expire.
What went wrong
According to a Logitech support page and posts on Reddit from Joe Santucci, Logitech’s Head of Global Marketing, the root cause was a certificate used inside the apps themselves.
“The certificate that expired is used to secure inter-process communications and the expiration results in the software not being able to start successfully,” Santucci wrote.
With that certificate no longer valid, Logi Options+ and G Hub simply fail to start. No running app means no access to your macros, custom key layouts, DPI tweaks, or app-specific profiles — everything falls back to the devices’ built‑in defaults.
Santucci didn’t sugarcoat the mistake:
“We dropped the ball here,” he said in another post. “This is an inexcusable mistake. We’re extremely sorry for the inconvenience caused.”
Why the apps can’t auto‑update
Logitech has already shipped patches for both apps with a fresh certificate. But there’s an extra twist: the broken certificate doesn’t just stop the main apps from working — it also breaks their built‑in updaters.
So the software can’t fix itself.
There’s no automatic update path here. If you want your Logitech customizations back, you have to:
- Manually download the patch (or the latest full installer) from Logitech for Logi Options+ and/or G Hub.
- Run the patch for each app you use — fixing one does not fix the other.
Once patched, the apps should launch normally and your previous settings should reappear.
A big catch: don’t reinstall
Logitech’s FAQ stresses that the patch is designed to leave your existing settings alone:
“The patch will not affect the settings,” the company says.
But there’s a trap many power users will have already fallen into: uninstalling and reinstalling the app while trying to troubleshoot.
If you wiped and reinstalled Logi Options+ or G Hub before applying the patch, your old settings and profiles are gone. The patch can’t restore what’s already been deleted, and the FAQ notes that some users have already lost their setups this way.
Logitech’s advice now is simple: use the patch installer only. Don’t uninstall first.
macOS versions that are covered
The current patch works on the last four versions of macOS:
- macOS 13 Ventura
- macOS 14 Sonoma
- macOS 15 Sequoia
- macOS 26 Tahoe
Fixes for older macOS versions "will be made available at a later time," Logitech says.
Separately, it’s worth noting that Apple is only shipping security and Safari updates for macOS 14, 15, and 26. If you’re on something older and your Mac supports a newer release, you should consider upgrading rather than waiting for a legacy patch.
Why this matters
On the surface, this is just an expired certificate. But the fallout underscores how fragile modern peripheral ecosystems can be. If your keyboard or mouse depends on complex desktop software, a single missed renewal date can suddenly brick your workflow.
For now, the fix is straightforward but manual: download Logitech’s patches, install them for each app you use, and avoid reinstalling if you value your custom setups.
